Halo: Reach

I finished this achievement but it didn't pop because, I think, I had to reload the second half of the mission and it automatically put it on normal, I restarted the mission on legendary but I guess all the messing about made it not count for some reason. so just be careful with loading your game. Anyway here are some pointers for getting through Legendary.

Note: Needler rifle or DMR, I chose DMR because when using the Needler rifle the elites roll out of the way more. (I guessed because of the super combine it counts as an explosive.). I kept both with me anyway because plasma rifles are ALL over the place so there is no point taking up a slot in your inventory, just swap and swap back saving ammo.

1. trying to force checkpoints by backtracking. It wont always work but when it does it will save time and stress.

2. Dont forget you can trade weapons with your allies, and most importantly they have unlimited ammo. so give them rocket launchers, Spartan lasers, plasma grenade launchers and they can help a lot, they take off the shields so you save ammo. They wont often finish them off so keep an eye on what there doing.

3. When you clear one area always have a look around for grenades and weapons, most of the time there will be a sniper rifle liying around, use it to clear out the next area before moving on, use up the ammo then get your DMR back (unless your a no-scoping genius, dont take it with you.) this particurlaerly helps at the end of level 7.

4. DO NOT underestimate the plasma pistol, This gun got me out of some bad situations many times. charge and hit/head shot for elites, works great on grunts if you need to save ammo, great for jackals with shields, plus they are all over the place.

5.Level 4, Nightfall. You could try this to get through the level with absolutely no big battles. Or if you don't want to miss all fights maybe just try the door glitch to avoid the hunters.

6. Level 6, at the end you will have to fight 4 elites, each with their own explosive weapon. stick to the bottom level just inside the grunts re-spawn door (don't worry none will spawn after this point) use grenades and your favoured rifle and the bubble shield as this restores health.

7. Level 7, Exodus, About half way through when your waiting for the elevator and the drop ship drops loads of brutes and 2 hammer guys. If you go through the door nearest the elevator on the same side as the drop ship you will find a machine gun this will come in handy. try to get it before the drop ship comes.

8. Level 8, New Alexandria, where you come up against 4 hunters, you can kill two from the back before going down the steps if you have enough ammo, with the 2 that are left if you go down the right (keep as far right as you can) you should be able to just slip by them easily then go back the way you came. you could probably do this without taking any of the hunters out but I didn't try that first so Im unsure.
Edit: Thanks to NoRmAlMaNzz and Violent Jay 24 for confirming you don't need to kill any of the hunters.

9. level 10, The Pillar of Autumn, Right at the start if you take cover behind the tipped up truck most of the enemies will go under the bridge this will give you time to cross the bridge for a DMR and you could just jump on the mongoose without bothering the elites.
After you clear Boneyard (this is the multilayer map name) before you go through the door, make sure you leave with a Spartan laser (with full ammo, found under the middle platform and another on the top of the middle platform.) and a long range rifle. After you go through the corridor you will come to a room with about 3 elites try not to use all you rifle ammo on them you will need at least 10-20 bullets for the next part, also don't try to shoot the 1st elite through the window because for some reason he is impossible to kill this way and you will use all your ammo trying. After this room you need to fight 2 Hunters and some little guys, this is where your Spartan laser will save you a lot of trouble. 2 hits on each Hunter will bring them down and the rifle will save you from going in the room to take out the little guys. in the room after the hunters watch out for an invisible sword wielding elite.
Then it's mostly trial and error till you get on the MAC cannon at the end for this part it is very important to prioritise. Drop ships ABOVE you are most dangerous then banshees then drop ships on level with you. they don't shoot until they get to a certain hight and shooting them unnecessarily will use up to much time, also be charging the gun as you turn don't wait to spot something.

EDIT: Matzaklr has confirmed you can actually get out and take cover behind the MAC cannon then just hop back in when the ship comes in to place, I did this the second time round on co-op and it is easy. But it's personal choice really I quite enjoyed shooting on such a big kick ass gun lol.

EDIT: iceman00behave wrote a comment with ideas to help you through Boneyard, Here is a copy and paste:
"I've got a few tips to make your life easier in the boneyard section of The Pillar of Autumn. First of all, make sure you get the drop shield and a DMR as soon as they become available, and keep the drop shield for the entire mission. When you get to the boneyard make use of the TWO lasers that are present (one on the ground found by walking to the right past the dead marine, and one upstairs to the left) to take out the 2 ghosts and the turrets. My advice would be to use one here and then take one with you for the upcoming hunter area (as youDOORnob stated). Also, there is a sniper rifle on the top level as well so make good use of that before continuing on (I used all the ammo and then picked up my DMR again). Once you clear the area, go toward the base as far left as possible. This will take you up a flight of stairs and put you on the 2nd level. When you get to the top there will be a doorway in front of you and then a doorway to the far left. Inside there is an elite on the catwalk by where you go in, an elite on the catwalk directly across from you, and 2 (i think) elites on the ground floor in the middle area along with some grunts (just to clarify, this is where the core is located on the multiplayer map). The next checkpoint is right past the door on the ground level. The trick here is to run through the door on the far left (past the elite) and then drop down behind the enemies on the ground level. Upon landing, immediately activate your bubble shield to shield you from fire and run into the doorway. Keep running straight ahead - the door will permanently close and you will get a checkpoint. This should save you some time on this particular area."

EDIT: here's a little Easter egg that will help with the long fight before the MAC cannon.


That's pretty much it. If you get stuck message me and ill tell you how I got through it, If I remember.
And remember if a girl can do it so can you =D

A lot of great tips have already been outlined above, but I will go over some main points that I utilized to make it through this game on Legendary, followed by some tips that are mission specific that I found to be effective.

*** Generic Tips ***

1. Long Range Weapons
Keep a long-range weapon in your inventory at ALL times. Whether it be a DMR, a Needle Rifle or a Magnum. This is not too hard, given the amount of ammo boxes and dead Marines for human weapons, and the Skirmishers/Elites that use the Needle Rifles.
--If you ask: "which is better?" I'd suggest the Needle rifle if at all possible. The main reason being is that it's 100% effective with headshots - 1 headshot to an unshielded enemy = kill. (With Brutes you need 1 or 2 extra bullets to remove the helmets on the infantry and Leaders, and the Heroes have energy shields as well.) The bonus feature with the Needle rifle that makes it somewhat superior to the DMR is that 3 needles into an unshielded enemy creates a supercombine explosion - which instantly kills the target regardless of rank, and gives very minor damage to anything that is standing within 2 feet of it. This is handy for when headshots aren't possible. Now, it is harder to find ammo for this gun, so if you want to rely on the supercombine be a bit more conservative when firing.

2. Secondary Weapons
A great secondary weapon to have is the Plasma Pistol. You might think "oh, that gun is super weak!" Well, it's not. Remember the Plasma Pistol from Halo CE? Well, it's like that. Really powerful. Not only can it disable shields and vehicles with an overcharge shot, it can kill a Grunt at any distance with 3 bolts, and is remarkably accurate. If you are patient enough, you can easily take out an Elite solely with the Plasma Pistol as long as you have good aim and a quick trigger finger.
However, when encountering large amounts of tough enemies, I try to get a Shotgun. Every shot fired is either a kill or it will stun an enemy long enough for you to get in a quick melee or another shot. (Or switch to your long-range weapon and go for a headshot).
If you can find a heavy weapon (such as rockets, fuel rod cannon, plasma cannon, laser, etc) - and you KNOW there is a use for it like vehicles to take out or LARGE clusters of enemies, do that but ditch it immediately once the ammo is depleted or it's usefulness has run out.
-- Another tip is if you traded a good weapon for a heavy weapon, and the HW is empty, memorize where you dropped your previous weapon. If you haven't progressed that far in the area, take the extra 30 seconds to run back and get it. This also works for ammo - you can still backtrack a bit to go to ammo crates and restock.

3. Take It Slow!
Legendary difficulty isn't about running into a group of enemies and shooting their faces off Rambo style. You will die in an instant. The best way to approach any group of enemies is to start with the smaller targets. The way I did it was to use a long range gun to take out Grunts first, followed by Jackals/Skirmishers, then the Elites or Brutes. The only exception to this rule was if a Skirmisher flanked me (which they will often do) and I will take it out first. If you do not fire upon the high rank targets, they usually will not advance on your position but rather fire at you from a distance. In actual fact, I found the Grunts and Jackals to be more menacing if they are left in a group rather than a single Elite or Brute.
Now, once you do that and all thats left is 1 or more Elites/Brutes, here is where patience is the key. Elites tend to flee when they get low on shields or health, so being in a position where you can see behind their cover is a plus. What I usually did was pick them off with the DMR or Needle rifle, firing slowly into their head when it was visible. Once an Elite's shield drops he gets stunned, so use that 1 second to fire one last headshot, and the enemy drops.
--Another tip (once the Grunts, etc have been cleared) is to take out the Elite/Brute that is holding the most lethal weapon. Examples: Fuel Rod Cannon, Plasma Launcher, Concussion Rifle. These weapons are HIGHLY effective against you, so the faster you clear them off the battlefield, the better.

[EDIT] an exception to the above is if you have a Sniper Rifle on you. Then, by all means target high rank enemies first.

4a. Allies
Don't always rely on your allies. The Marines tend to die extremely fast, and even if you give them heavy weapons they still tend to do the same. Also they aren't all that bright - they will shoot you with rockets if you're in fist fight with an Elite, or snipe you/through you when too close to an enemy. Also, I've seen them shoot themselves with said heavy weapons. So my advice is: Don't bother. The best way to make use of the Marines (unfortunately) is to use them as bait/a distraction when facing multiple high rank targets or Hunters.
Occasionally you will get another Spartan(s) as an ally. They are slightly more reliable in the fact that they can't die. The trade-off is that you can't exchange guns with them. Now, they act the same as the Marines; meaning that if you are in close-combat with an enemy, they can and will shoot through you to kill them. Just be aware of this.
-- If you are facing a group of tough opponents, a good thing to try (when possible) is to move as close as you can to said enemies, and your Spartan ally with follow you, allowing the enemies to target him/her instead, and the Spartan will retaliate. They do quite a bit of damage against enemies, which will help you get the kill if they don't do it themselves.

4b. Allies & Vehicles
My number one rule is as follows: DO NOT LET THE FRIENDLY AI DRIVE THE VEHICLE THAT YOU ARE IN! This is insta-death. The friendly AI in this game (on Legendary in particular) have no concept of moderation or patience. If you hop on the turret of a Warthog and a Marine or Spartan hops behind the wheel, GET OUT as soon as possible. The allies will just drive you right into the centre of the biggest group of enemies on the field and you will get obliterated.
If you must, drive the vehicle yourself and have an ally use the gun. This also isn't always effective because the friendly AI tends to only fire when the enemy is very close to you, and then they usually only fire in short bursts.

This brings me to my next point:

5.Vehicles
Sometimes it's better to not use a vehicle, even if it's available. The reason being is that you can either find or are given sufficient power weapons to take them out manually, or you kind find great vantage points that allow you to take out the enemy vehicles at a distance.
If you feel a vehicle is needed, firstly follow my above rule (never let friendlies drive). Secondly, be patient. All enemies do much more damage to you and your vehicle so coming in close and fast to deal damage isn't usually effective.
Stay away from Ghosts if at all possible. Their guns are weak and hard to aim properly, especially when it's damaged (they fire in random directions). Gauss and Rocket Warthogs are good to have if you can get one. The Gauss is a 1 hit kill for most things, and a 2-3 hit kill for tanks.
--Tip: Let a Marine take the gun at first, and drive on the "fringes" of enemy clusters - at enough distance so enemy fire is limited, but close enough so the Marine can shoot. Chances are, the Marine will die. Take this opportunity to park the Warthog (or whatever you have) at a good vantage point and slowly snipe out the enemies with the gun at your leisure. If another ally happens to get behind the wheel, just hop out and kill him. If it's a Spartan you'll have to play a game of "Jump out, Jump In, shoot, Jump out, repeat"

6. Using Checkpoints Intelligently
What I've noticed about this game is once you clear out an area or are close to clearing it out, you can get checkpoints at regular intervals. This is extremely useful!
Example: You are fighting a large number of Brutes. You run out of ammo for your DMR but you remember that there was an ammo crate back at the entrance to the building. You go back, and restock. What you can do here is get to a good hiding spot, and wait. Usually a checkpoint will pop after a couple minutes - this way if you happen to die you don't have to re-kill all the enemies you took out, and have to backtrack again to get more ammo.
I've also noticed the further you backtrack, the more often a checkpoint will occur.
--Sometimes you get a checkpoint in a bad place. Such as you have ran out of ammo for your main weapon, and your backup will be of no use in the situation. You keep running out and dying over and over and you can't seem to figure out a way to get past this without restarting the whole mission and doing it again.
Don't fret! A simple way to fix this is to commit suicide repeatedly. The game's mechanics have a "failsafe" feature that will shunt you back to the previous checkpoint before the bad one. (like if you got a checkpoint when a Fuel Rod Cannon shot is inches from your face). After a certain amount of deaths in quick succession after the checkpoint loads (I think around 10) the failsafe kicks in and you will be pushed back to the previous checkpoint. This gives you a chance to learn from your mistake and get more ammo or position yourself better for next time.

7. Fights Aren't Always Necessary
There are a few rare instances where battles can be avoided by either taking a stealth approach, or sprinting past the group of enemies. I will outline ones that I've found below.

*** Mission Specific Tips ***
Here I will outline some tougher areas of some of the levels and explain tips I used to get past them.

Winter Contingency
I didn't have much trouble with this level, but one part near the end is a bit tough. When you get in the Falcon and fly to the relay outpost, there is a part there where you have to defend Kat while she wires a door to close. You don't actually have to fight here. Instead, clear a path to the door and get inside. All you have to do is sit in the farthest corner away from the door and let the other Spartans do the work. After a few minutes, the door will close. I never was hit by any grenades or Concussion shots that happened to make it through the door.

Nightfall
The main thing here is to find and use the Sniper whenever it's available. One of the civilians you have to save (but can't, because they die so fast) has one, so take that ASAP and pick off the Elites.
After you follow the riverbed to the spire thing, Hunters will appear. Be aware that it is possible for Jun to get knocked off the cliff. He does not spawn back up top. Restart the checkpoint immediately if you got one from BEFORE his cliff-dive. If you are unfortunate enough to have a checkpoint pop after he falls, just activate the failsafe. I've also been told that if you wait an obscenely long time (15 minutes) the door will open by itself without Jun's codes. But I have not proven that myself.
After you get through that gate, you will cross a bridge that's attached to a rock wall. There will be a Sniper Rifle in a hard case next to a rock on the bridge. TAKE THIS. I never noticed it until I backtracked for ammo, It will make it tremendously easy to take out the Spec Ops Elites with Focus Rifles.

Tip of the Spear
Keep the Warthog for as long as possible. Try to boot Kat out of it ASAP so she doesn't drive. Fire the turret at the AA gun where the gun connects to the base, and you can kill the AA gun without having to go inside. This takes a fair bit of shots though, so be aware. One thing I found was that I let Kat take the gun, and I drove slowly towards the Gun, and she took out most of the infantry that was guarding it. After that, I traded seats, and then hopped right out and took the drivers seat and sped off back to where we came from. She stayed up near the front firing at the Ghosts, and I was able to park the 'Hog farther away and take out the AA gun, the Sniper nest, and the Ghosts from across the entire area. After that I let her have the gun until we came across the Wraiths. I stayed back and picked off enemies, and she drove into the centre of the group and the Warthog exploded. She fought the Hunters and Wraiths by herself. I managed to kill an Elite with a Plasma Launcher ant took out both Wraiths with it. I used small arms to slowly take out the Hunters, and we got the Evac checkpoint before all the enemies were killed.

Long Night of Solace
All I really did here was I stayed sort of behind Anchor 9. Very few enemies came back there, and I let my allies fend for themselves. I'd then pop out occasionally and take out a couple Seraphs and Banshees, then retreat back behind the station. It worked well to keep me alive, since I've noticed it's actually hard to avoid enemy fire once they have a lock on you.
Once I was on the Corvette, I waited for the 2 Spec-Ops Elites to jump up into space, and took them out one by one. I had a Shotgun and a DMR at the time. Then I floated down onto the central support nearest the energy shield blocking the ship from space, and headshotted each other Elite one at a time.
I ran out of ammo for the DMR and was forced to use a Plasma Pistol until I picked up a Needle Rifle from a Spec Ops Elite. There is one room where there are Elites with Needle Rifles and Focus Rifles, and Grunts with Fuel Rod Cannons. Take out the Grunts first, and don't worry about the Engineers. The shields they provide are actually very minimal.

Exodus
There will be a point where you have to defend an elevator. You can go outside and utilize the turrets that are set up, but I stayed inside. This keeps you safe from the Phantom's gun as well as the Plasma Turrets on the side. The Brute Heroes with the Gravity Hammers are your priority. A well placed grenade followed by a couple headshots does the job in no time. There is also an ammo crate down the central staircase. (IIRC... If not, its a dead Marine with either a DMR or Assault Rifle)
The hardest part of this level is towards the end where you have to activate anti-air defences. I still had the jetpack from earlier in the level, and I advise you to keep that. I had a DMR and an assortment of secondary weapons until I took a Fuel Rod Gun from a fallen Grunt. I used this and the Jetpack to take out both Wraiths. Getting into the central building to activate the guns was the hardest part of all. There are several Brute Heroes, and one has a Gravity hammer. There are also several Leaders and Infantry. It is nearly impossible to get up there. The Marines that re standing at the central staircase are useless. I don't know if it's a glitch in the game, but they don't shoot and enemies don't target them. Not only that, but Spirit dropships come by every so often and drop Ghosts behind you, so you can't even take out the Brutes slowly.
What I did was I ran to the right of the central stairs towards the high wall, and jetpacked straight up, and landed on the window sill where the button is. I pressed it and immediately ran off down the stairs. Mission complete.
That may take a few tries, as the enemy spawn locations are random, but there is ALWAYS a Brute Hero with a Hammer and one with a Fuel Rod Cannon, and 2 Leaders with Concussion rifles.

New Alexandria
This mission isn't too terribly hard. After you clear the Hospital and have to go to the nightclub, there is an Easter Egg which can be unlocked that replaces the Hunters with dancing Grunts and Brutes. Someone above has already linked that video in their solution so I don't feel the need to relink it. However - 90% of those Grunts will have Fuel Rod Cannons, and there are around 20-25 Grunts in that room, and 5 Brute Infantry. You need to deactivate the jammer to complete the mission. When you do so, the music stops and everyone starts shooting at you. It is impossible to just sprint out of the room and survive. You WILL die.
You can choose to face 4 Hunters and a small handful of Grunts or do it using the Easter Egg. I used the Easter Egg method. What I did was I ran in an killed the Brute DJ (killing any Brutes or Grunts also stops the music) and ran out of the room. I slowly picked off the Grunts as they came up the stairs, and 'naded the ones that didn't. I took that opportunity to acquire a Fuel Rod Cannon with full ammo.
There will be a point where you need to kill Elites and Engineers on a roof. This is very difficult as there are groups of 6 Banshees attacking you at the same time. What I did was I flew to the top of Club Errera, and picked off the Engineers with the DMR. Then I flew down, took out the Banshees and quickly bombed the Elites before more Banshees spawned. I then landed at the club and pushed the Falcon off the edge and called for Evac, which gave me a brand new Falcon.
Once you go to kill the last Jammer, you can actually fly the Falcon into the lobby of the building through the back. I did this and eliminated all the enemies in the lobby very quickly. After the jammer was deactivated I ran AS FAST AS I COULD toward the elevators, killing maybe 2 Drones on the way.

The Package
After I got the Scorpion, I went very slowly. I took out targets as soon as they were visible, and focused on Banshees, Ghosts, and Turrets when I saw them. Again, you can take out the AA guns at a distance. I was able to keep the tank alive for the "Tank Beats Everything" achievement.
Once I got to the "Defend Halsey's Lab" part, I only activated the closest turret. I grabbed a Jet Pack (located on the far right hand side of the door, on the wall) and stole a Banshee. I focused on taking out the other Banshees first, followed by Wraiths. I then performed bombing runs on the enemies in front of the door when I could. I didn't die at all this way. There will be a point where a Phantom drops a pair of Ghosts. I landed on top of the door to the lab, dropped down and took the Laser that is in a hard case in front of the door. I used this to take out the Ghosts. The reason being the Ghosts are RIDICULOUSLY accurate in their fire and took me out 100% of the time even though I was flying high in the air - not to mention they are driven by Elites which requires more than 1 Banshee Bomb to kill them.

The Pillar of Autumn
Right as the mission started I managed to jump down and land on the Elite next to the overturned truck. That took out his shields while not damaging mine and I head-shotted him with the pistol for the kill. This is also where you can get the "If They Came To Hear Me Beg" achievement.
When you get to the Mongoose(s), there is a house with a rocket launcher and ammo inside. Take it, as it will be useful later. When driving the Mongoose, don't stop for anything. Once you get into the clearing with the Scarabs, it may seem safer by just driving straight through underneath the Scarab. It's not. You will likely fall off and get killed, also the Plasma Turrets on the Scarab can see you and do tremendous amounts of damage. Just follow the road and you will be fine. You will still take damage, but you shouldn't die as long as you don't slow down.
After I got across the bridge I used the Rocket Launcher on the Grunt methane thing which killed most of them instantly, and used the remaining rockets on the sniper tower and a group of Brutes. After all the infantry were dead, I took a plasma pistol and overcharged the Wraith. I head-shotted the gunner, boarded and melee'd the driver. This left the Wraith intact and driveable. I hopped in and used it to take out the Suicide Grunts and the skirmishers coming down the hill from the cave with ease.
Once inside the shipyards you are first confronted with many Elites with heavy weapons. I had a Needle Rifle and a shotgun, which I traded for a Laser that I found next to some dead Marines. I focused on the Elite General with the Fuel Rod using the Laser, followed by quick head shots. I did the same with all the Elites. Once you get to the centre wall, I went up the stairs and took another Laser located against one of the middle upstairs doorways leading out to the enemy (the "Boneyard") I used it to take out the Fuel Rod Turret and the Ghosts. I then used a Sniper Rife (against another doorway not too far away) to take out all of the Elites, and DMR'd the Grunts. (There is a DMR up there as well as on the ground against the huge centre wall at the only doorway through)
I went inside the building along the long catwalk and helped Emile kill the Majors that were inside. I then restocked on DMR ammo which is located in the little hallway leading into the room where the "core" is kept in Invasion. It's a weapon crate/locker.
Once I got to the Mac gun, I just crouched behind it on the staircase until Keys started yelling "SHOOT IT NOW!", and then I ran up, hopped in and fired. Mission complete.

/end

Good luck, and remember - be patient!

The key to this achievement is patience. For most people, this will be pretty hard. Take your time, use cover effectively, and manage your ammo. Also, extensive use of an overcharged plasma pistol to strip their shield and then a quick headshot will prove to be helpful against the mass of elites. You may need to playthrough the game once before to learn the best routes for some of the objectives. Also, at some points, you don't have to fight. Sometimes there is a route around the enemies or you can quickly run past them to the next check point. Stick to it and you will get this achievement.

TheDarKnyht also has some helpful advice:

The needle rifle plus plasma pistol will take you through most enemies in the game. The needle rifle supercombine explodes after three hits (which kills grunts, jackels, brutes, basically anyone without shields), plus the rifle is good for headshots. The plasma pistol is handy to knock out shields before either shooting them in the head/supercombining them. The DMR followed by the Pistol is handy if the Needle Rifle isn't available, but you need to be accurate with these.

[EDITED AND UPDATED]when i first wrote this it was a little cluttered, hopefully this will be a little more organized. i'll break it down into a few sections and hopefully it will be helpful.

The Enemies-
Grunts: these will be taken care of most easily from maximum distance with weapons such as the needle rifle, DMR, or plasma pistol. they shouldn't prove much of a problem, as almost all grunts only require 1 headshot. take your time and make sure to line up the shot, so you don't waste ammo.
Jackals: these guys are a bit more trouble than the grunts, they are slow moving like the grunts, but often carry shields or more effective weapons. when dealing with the shielded variety you have 2 options, you can get rid of the shield with an overcharged plasma blast and go for the headshot with a precision weapon, or aim for their exposed hand, which will reveal their head. this can be a little tricky at times, as their hit box is rather small and the timing will take a little getting used to.
Skirmishers: similar to the jackals, but much faster and more agile, same thing, go for the headshot during the brief periods they stop moving to preserve ammo.
Elites: these guys are very smart, quick and agile. you can waste whole clips and still not get the kill if you aren't approaching them correctly. typically the best way to go is an overcharged plasma blast, followed by a quick headshot with a precision weapon.
Vehicles: same as elites, use the overcharged plasma pistol, but then go for the hijack. after you hit it with the plasma pistol, have another blast ready in case you don't get to the vehicle in time. with wraiths take out the gunner before trying this. also it's not advised to use vehicles too extensively, they usually just make you a bigger target.

Weapons-
As i have somewhat already laid out, it's best to have a precision weapon (Needle Rifle, DMR, or Pistol) and a plasma pistol. I favor the Needle Rifle, because it's shots seem a bit more precise than the other 2 and it's an enemy weapon, which equals more ammo. with power weapons, like rockets, give them to A.I. characters if at all possible, they are very accurate and when they have these weapons, ammo is unlimited. if no A.I. is available you may want to replace your plasma pistol slot with it. when you start new encounters, drop it and remember where it is. once you've killed everything in an encounter go back and grab them (save them for when absolutely necessary).

General Tips-
Try to stay as far from the action as possible, and take your time. Also, once you've killed a couple enemies, backtrack to previous areas to try and force checkpoints (this won't work all the time) to prevent having to clear whole sections multiple times. most of the time you can move into the action and then back away, letting whichever member of noble team you are with do a majority of the heavy lifting, while you pick off the easier targets (when doing this, you will usually have to move forward far enough before they will help). If there is a section that is giving you a particularly tough time, backtrack to previous areas and explore a bit, there is usually a sniper, rockets or precision weapons that you didn't see.

My Final Section: DEALING WITH HUNTERS-
Oni Sword Base: there will be 2 before entering the Sword base, after you activate the comm's array and the AA gun.if you did the comm's array second, you will find that there are rockets in the building that you hit the second switch.these will be very helpful. Save these and all your grenades and you shouldn't have too much trouble. if these don't finish them off, use Kat as bait and try getting a cheap shotgun blast off in their back (shotguns are all over by these guys)
Nightfall: when you get to the part where Jun plants the bomb in the transmission disruptor, or what ever, you will once again be able to find rockets. if you were able to save the militia men in the section before, yo'll get them there. if not, you can find them where rockets spawn on the multiplayer version of the map (if you aren't sure where this is, go to custom games and select powerhouse, you'll find them in the water, next to the actual powerhouse). if you get both, you'll have 4 rockets. this and a sticky for each should do enough damage for Jun to finish them.
Tip of the Spear: at the second AA turret you have to destroy, 2 more are waiting for you. I'm not sure if you actually have to fight these, but there are a couple of plasma launchers in the area that, if not used on the wraiths in the area, can take them out easily.
New Alexandria: there are 4 that are in the first area that you need to go to. However, they can be totally eliminated by activating an easter egg. i will post the link at the bottom. if you don't do that, you can still try running right past all of them and hitting the switch that you need to without a fight at all.
Pillar of Autumn: once again, i've been informed (although i haven't tested it out) that you don't have to fight these if you break out some glass next to the door and jump through.

if there are any hunters i forgot, or i have not mentioned something that you need help on, please comment, also i hope this is a little easier to use now :)
here's where you can find the easter egg to get rid of the hunters in the mission New Alexandria

I would write SPOILERS but since this is an achievement guide I assume you know there will be some gameplay (but no storyline) spoilers.

Most of the essentials have been covered. DMR/Needle rifle are your friends. Force checkpoints. This works on most levels. Run past whatever you can. You wont know you can't until you've tried it a few times.

Tips for the last four levels:

Final part of Exodus (arm and lauch missles):
This can be frustrating because it was one of the areas that does not do the extra checkpoints. The good news is this can actually be done really quickly with some good tactics.
I used the hog to kill a ghost driver, took the ghost behind the nearest missle launcher then jumped up hit the button and jumped back behind it. If you notice there is an active cloak powerup next to the missle launcher. Wait until your friends have the covenant's attention then jump back up and grab it.
Take the ghost to the next missle launcher, activate camo and press the button. You should get a checkpoint. Note that now all the enemies retreat to cover the final activator.
What you need to do is take the ghost back to the beginning of this area and grab some life. Gun the ghost up the stairway on the far right side (where you are) hopefully killing some enemies along the way. When you get to the top of both staircases, jump out and take the stairs UP. Wait a little bit then activate camo, carefully go over the edge to land in the planter box outside the room with the missle launch console, jump up and activate it. Mission accomplished and you barely had to kill a grunt in the last section.
If you are having trouble getting to that last activator. I would suggest thinning them by luring them to the left side of the map by going over there and shooting some.

New Alexandria: This is tough, your falcon will take a beating but it is possible. You will have to kill most of the enemies but there are parts where you can run past them (the little flying bug enemies after the first jammer is one). Another is the hunters at the third jammer. If you have the jump jet equipped you can jet to the jammer, quickly hit the button and then jet backwards ASAP. Someone else said it never allowed them to activatge until at least one hunter was dead. I did not have that problem. I'm not entirely certain it actually prompted me to press X but when I ran there, pressed X and escaped it counted it.

The Package:
I am not entirely certain I did this right because it took forever for the scientist person to open the door. But it worked. Let the turrets do the killing. I stayed behind turret C as much as possible. It has the best angle of attack on covenant attacking your teammates and gets destroyed a lot, requiring you to fix it. You will get a checkpoint almost everytime you get near a turret or at least once you activate/reactivate it so exploit that well.
Im not sure this is correct but it seemed that the radio messages that indicated you had made progress came when all four turrets were online at once (not an easy accomplishment). Of course it may also be that there were enough enemies dead and that is what allowed me to actually get four turrets activated so that is just a coincidence.
There is a SPKR and a Spartan Laser for you to use on the Banshees and the lone Wraith that will be raining down hell. The Wraith is outside the playable area and is tough to get an angle on, but if you jump on the rocks behind turret C you can get on the roof of the building behind turret B and get a good angle.

Pillar of Autumn:
It takes a little luck, but until the very last section before the MAC gun you don't have to kill many enemies. Just run/drive past everything. Sometimes you have to thin the herd a bit, but dont try to kill everyone. It takes a little luck to make it through sometimes but I got plenty of checkpoints. One place you cannot do this is when you get the the narrow canyon as there isn't really room to run past the flying bugs so you do have shoot all those little %@$#%. When you get to the final area before the MAC cannone you do have to kill EVERYTHING. Force checkpoint was spotty in that area but worked enough that I got a checkpoint after every Elite Zealot I killed.

For all of these tips realize it does require some luck as well as skill. Once I figured out how I could successfully get around enemies, it usually only took me a few tries before succeeding.

This is just to help with level 6 Long Night of Solace.

At the start when you are dropped off on the beach by the falcon with the rest of noble team, make your way like normal to the ridge over looking the part of the beach that will be filled full of enemies.

Soon as you reach the ridge kill off a few of the grunts down near the water, and using the sprint ability as much as possible run along the water edge between the rocks, if done right the drop pods containing elites will drop behind you and you wont have to worry about them.

As you reach the section where the fight turns up hill keep going along the water front to find a gap between the rock wall and water, that looks like your heading towards a dock and the front of the base.

(KEEP USING SPRINT)

A dropship will turn up carrying a wraith, but if your fast enough with your sprinting you should be on the dock just before the wraith is dropped. Quickly turn right to face a door in the base and turn and run up the little path on the front of the base that leads up hill. Using Sprint you should easily avoid the plasma mortars of the wraith.

You will pass a few rocks and small barricades and reach what looks like a blasted out section of fence. if you go through you will be behind the enemies (who will mostly focus on noble team as they take the normal route to catch up with you) allowing a few easy kills. I suggest that you also pick up the drop shield ability once there to keep you alive in case any of the elites decide to turn their attention on you. That or you can hide behind the wall till noble team turns up and the marines open the door.

Also when flying around in space make sure to use LB lots, when ever you start getting shot at do a quick loop and 95% of the time your attacker will stop, Also flying behind the station will give you a moment to recharge your shields as most of the time you never get attacked behind there.

During the section where you must disable the carrier you can also use the Savanna to hide behind to get your shields and armor back.

Boarding the Corvette.

Straight after you land on the corvette you will be asked to drop into the comms room and kill all the elites. DONT DO IT. you will die almost instantaneously, instead wait a few seconds for a elite to jetpack up through the plasma shield, a few punches should finish him off, now run around the outside of the shield to a marine on the opposite side from you, another elite will jetpack up and will be another easy kill.
After taking these elites out you can drop into the center, try land so that you can assassinate the two elites at the consoles in the center of the room, and be prepared for a quick to use your bubble shield (if you picked it up before you took off from sword base) to stop most of the damage from the elites on the out side of the room. If you managed to kill off the two elites in the center of the room, make your way as quickly as possible to the outside of the room, the marines will drop in at roughly the same time you do and cause a bit of chaos that will hopefully lessen the damage you will take.
Use hit and run tatics and bubble shield deployments to take out the remaining elites, they will normally have duel plasma rifles that cause serious damage if you stay out in the open to long, the best bet is to try and use a DMR to headshot them.

On the upper level of the round room just to the left of the door leading to the hanger is a needle rifle should you wish to pick them up, as they will be a great help in the next couple of rooms.

In the hanger there will be 6 or so elites and alot of grunts, the best idea is to use the corridor from the comms room as an escape route to fall back should you want to heal with the bubble shield. There will be an ENGINEER floating above the grunts right in the middle of the room kill it with 3 needle rifle shots then try to take out the grunts, this will lessen the amount of fire coming your way, one of the grunts always has a plasma cannon, and forcing them to fight you down a narrow corridor is much easier then fighting them out in the open.

One of the elites also has the beam rifle which is the second biggest threat in the room. Straight out the door and to the left in the actual hanger you can walk up a ramp to another collection of needle rifles should you need more ammo.

Once you clear the room youll will have to fight your way to the bridge, there will be a group of marines with you, but they dont really survive to long. As the doors open a few grunts will appear in the door in the middle, and the left hand door. Also in the middle door will be 2 elites with needle rifles, they wont be afraid to spam grenades. Try going through the left door and attacking from the side, try to conserve ammo, and clean head shots will finish them off reasonably fast.

Heading down the sloped corridor you will appear in a room that shows a view of the Savanna being pounded by the covettes guns. There are two elites hiding in the room, one by the window watching outwards and one just behind him.
If you have any marines with you, be quick, as they will attempt to shoot the elite by the window and cause a firefight. Instead run ahead along the overhang, and locate the second elite hiding between the servers (only because thats what they resemble to me lol), assassinate him and quickly run over and assassinate the elite by the windows.

After the winding corridor you will be in the bridge, there are a 3-4 normal elites (1 of which is invisible with a sword) in here with a elite general (concussion rifle) and a few grunts. Try to sneak around and assassinate any elites you think you can pick off, the one looking at the terminal closest to you on the right hand side of the world hologram is normally the sword guy. Use the bubble shield and any walls to try to avoid the general as the concussion rifle is incredibly overpowered against you. Pick off his friends and then go for him, Dont try to kill him with the swords as he will more then likely stomp you into the ground.

After turning on the refueling switch a elite with some grunts and jackals will appear at the door leading back to the hanger. Head shot as many as possible and be careful of the suicide bombers. you may want to switch the DMR with a needler.

Back in the hallway where the savanna was destroyed the door on the far end will open as you enter the room, a well placed plasma nade will take out the grunts and hopefully the jackal leaving the elite to be killed with the needler.

Then back in the hanger, do not leave the corridor, kill off any easy targets with the needle rifle and let Jorge do most of the work. Once the room is clear you can enter, there will be a plasma nade launcher on the ground you can swap the needler for. but you will have to fight 2 elites and grunts that stay on the upper levels on the opposite side to the corridor you just entered from. Try to pick off the grunts before moving to take the elites out with the launcher. They will eventually come down onto the main floor, but most of the time run back up to hide.

Once you have dealt with them, head as fast as possible back to the corridor leading to the bridge, elites will enter the room from each corner, from the corridor you should be able to pick them off slowly, but try not to over expose yourself. The elites will never enter the corridor, but will be more then happy to throw a few nades or shots your way. Jorge will help out now and then, but he is hardly the spartan you are.

Patience and timing with bubble shields and headshots should take the elites out slowly while keeping you alive, use the nade launcher if you have any left and feel you can get a cheap shot or two in the back and you will hopefully not have to much trouble.

Spoilers Ahead!


Just got this one with alot of help from the posts here. Dunno if it was mentioned but on pillar of autumn, there is one of those floating enemies that gives others an extra shield where you need to go to the mac gun, I used the hologram decoy and ran in and shot it down, after that it was overcharge and headshot the elites. But I kept dying on the mac gun. Until I didn't get in it and hid on the stairs just behind it, the drop ships don't fire While you are hid and the corvette still comes in. Wait till keyes says to shoot it and jump in and you should just get the shot off before you die and get the cutscene, then my achievements for legendary and alone popped up. Good luck

in addition-
dont forget the noob combo folks: overcharged plasma pistol to drop shields one dmr shot to the face.
other good headshot weapons include the sniper rifle, needle rifle & magnum.
this should help with low ammo issues and taking down the annoying white elites.
THE PLASMA PISTOL IS YOUR FRIEND. use it. also remember to pick up new ones as overcharged shots chew through its charge.

timesaver: remember to sprint through the first level and remember to glitch skip nightfall
(utube if u dont know how)

for the final mission - when you get to the hunter area kill all the shielded skirmishers then to avoid wasting ammo simply skip past the hunters by breaking the glass to the right of the door [i cant recall if its open or glassed] then simply bunnyhop [jump + crouch in quick succession] through it, pick up the dmr in the dark on the left, kill the cloaked sword elite and carry on... =)

if youre having trouble msg me on xbl - gt is: coreymawf i can usually get it done within a day depending on what time of day i start

Hope this helps
Happy gaming

Long Night of Solace: I was stuck on the 3rd part of this level FOREVER... the part where you land on the Corvette and jump down below the shield. Finally I changed tactics and restarted from the beginning of the level.

Before going up and doing the space battle, make sure you grab the Energy Sword, Sniper Rifle, and Bubble Shield. Then go up to space and do that battle then land on the Corvette (start of the 3-rd phase of the level). Kill the 2 Elites that jump up. Now you have the sword for easy kills when you jump down. I took the path with the little nook in the high walkway. 2 or 3 Elites are right near that point for quick and easy kills. Save the sniper rifle for the 2 rooms later on.

Without the sword, I was getting raped by the Elites. In the far room, there is a weapons cache with 2 new swords. You can use that to fight your way back.

Thought id give my opinion on how best to crack this beauty, Its taken me about 2 days to get through all the levels and that's 2 long days at that so don't expect this to be finished quickly.

For those of you out there who are maybe a little wary of starting this or think you cant do it... think again. As long as you are patient and learn from your mistakes when you die you will get there. Personally i found that playing 4 player co-op in legendary doesn't really match up to single player. They seem to put loads more elites etc on co-op but that may not be the case. don't know if any one can confirm that fact?

I did, however, find it useful to play some levels on co-op first because this helped me to work out which parts could be rushed/ sprinted past. Towards the end of the game ( a level i had not previously played) i tried to sprint around some elites just to find 2 hunters waiting around the corner and...... checkpoint reached. Not good, plus the elites continued to follow me so i would say on the last level at least clear areas out before you move on it will save you hassle in the long run.

As for the best way to actually kill the covenant the previous posts cover all the bases. The DMR will become you best friend along with the needler rifle.

The one thing that helped me out was trying to force checkpoints. So if i went into an area killed a few elites i would track back a little through the level then re-enter the area again. most of the time this resulted in another checkpoint (but not always).

The last thing to mention is really try to use your teammates. they may not be great at actually getting the job done but at least they draw the fire allowing you time to line up head shots with the DMR.

Hope this helps.

The Reach campaign on legendary solo was really not that hard. Sure, it's frustrating and highly annoying at times, but patience is the key virtue here. These tips have already been said, but that goes to show how helpful they are.
1. Killing the enemy is sometimes a bad decision, because you could save a hell of a lot of time and just run through them. The main places I can remember doing this was on Exodus at the end, Nightfall on occasion (not recommended though), and Pillar of Autumn, when you're battling the hunters.
2. try to save ammo on tough missions with little to no ammo around. If you end up wasting too much, just revert to last save.
3. It doesn't hurt to die (...kind of...). What I mean is, if you just got a checkpoint, and you're in a tough position, go berserk, and see what happens. You have nothing to lose.
4. The DMR and plasma pistol are your buddies here. Always keep an eye out for them.
5. Big, powerful vehicles are often not the way to go. They are slow, and leave you open as an easy target. Use ghosts alternatively, as they provide a fast getaway if your health gets low.
6. Use your teammates. Although thay almost never do anything, they distract the enemy, providing you with a chance to flank them.
When I did this campaign, I used the guides on the website below. In tough times, it really helped out.
http://www.gamerzines.com/guides/halo-reach/halo-reach-compl...
As a side note, if you thought Reach is a hard campaign solo, try Halo 2 on for size :D

I don't really have a guide or such but I'll tell you what helped coast me through this than my normal run'n'gun way.
-You MUST be patient! Take your time, there's not time based anything to worry about so pick your shots and make 'em count.
-Precision Weapons = Win. DMR's & Needle Rifles should be your best friends. Any given enemy aside from elites will go down within 4-5 headshots (patience). Elites will be the worst due to their high energy shields. Standard Brutes on the other hand, I've killed withing 3 shots to the head apiece.
-Plasma Pistols without the charge. The charge can help against elites (especially the final run of Zealots in Pillar of Autumn - that part took me 4 hours alone. Not the dropships, just the 4-5 frickin' Zealots dual wielding plasma rifles).
-Take out any engineers if around. They just keep refilling enemies shields if you get pinned down so it's wasted effort unless you kill them first.
-Nightfall - Do NOT rely on Jun for anything. He kept screwing me over and never taking shots he very much could've. Don't even kill, but help me out here bro!!! Any level with Jorge around, let him do most of the cleaning up.

That's my advice. Take your time and just move around a lot for checkpoints. There's ALWAYS ammo somewhere. You have to scrounge.

This guide right here is what helped me get through this tough adventure in 2 days. They help you find shortcuts and places that you can go through to avoid large battles. Although they are on Mythic Difficulty (All skulls on Legendary) I suggest not doing the same and not using any skulls except for IWHBYD and Grunt Birthday party. Just follow the guide at said link and bam one step closer to a completed Reach.

* I do not own any part of the guide*

This game on legendary isnt too bad. If you got through All the other halos on legendary, you should be fine, but you should keep a few things in mind:


First of all its going to take a lot of time. Just take your time with it, and dont try to beat it all in one day.

The way i got stuck 90% of the time was lack of ammo, so keep a close eye on how much you have, where other guns/ammo crates are, and try to get as many headshots as possible. To save ammo, you can swap weapons with a teammate (Excluding noble team) when you have one shot left for another weapon. That trick saved me a couple times.

Dont play through it like your playing online. Sit back before a fight and check out whats going to happen, and where you can go if you get caught in a tough spot. Usually before a big fight you will find at least one health pack along with a DMR. You will also encounter these through tougher areas of the levels.

You can always restart from your checkpoint, so if you die its not the end of the world. Trial and error plays a big part, especially if your trying to play solo legendary first time through the game like i did.

Try to stay away from close combat the best you can. Elites can be tough and will take you down in a matter of seconds, especially if your too close.

Weapons like the needler or plasma pistol can and will save you many times. Dont under estimate them!

If you need anything more specific, let me know ill be glad to help. Good luck!

InvisibleCow1 is right. I've started using it only closer to the end - DRM was enough with clever shooting. But Elites at the later stages are very annoying. So you charge plasma pistol, shoot their shields down, DRM headshot. Master this combo and you can get by almost anything in the game.
Also note, that Invisibility is your best friend for sneak kills - move slowly, otherwise your camo fails!

The hardest part for me were the escape from Covenant Cruiser - the fight in the loading dock was sooooooooooooo long. What I did - hid in the corridor on the left side (with your back to your ship). Somehow enemies don't enter this corridor and lose interest in you when you move inside.

Enjoy, Kane and Lyunch 2 on Extreme is your next stop in "Annoying Chivos - I Haz No Life".

As much as I like flying and turning invisible never pass up a chance for Armor Lock or Drop Shield. Each one will keep you alive that much longer and drop shields will give you that extra health.

Don't rely on your fellow Spartans they are only very useful in specific locations, and in vehicle turrets. Heavy weapon ODSTs are your best bet (unless you're in a vehicle). Marines are good as well. Give them your heavy weapon when it gets down to 1 ammo. They have unlimited ammo. Fuel Rod and Rocket Launchers are the best for Marines.

In some situations you can skip the objective on the more linear maps. If fighting ain't your style see if you can't just run through it.

Try not to use power weapons on anything but Hunters and elites. If you can ever catch one of those squirrels on crack (elites) standing still, it's time to pounce. This is more likely to happen if you backtrack.

Force the checkpoints. Anything you can think of to change the are might help. Backtrack, blow up some vehicles, kill a marine. This isn't surefire but every checkpoint is worth it.

Plasma pistol + head shot weapon = win.

Wraiths are your friends. If you get into the turret of an enemy Wraith, they will abandon ship. Now you have a tank. NEVER pass up this opportunity.

Don't ever assume there isn't a useful weapon hidden somewhere around you. Almost every area has at least a shotgun or sniper hidden somewhere. You may need to fight your way to them though.

As a last resort. If you can't handle that one super awesome mega elite in an area. Your best bet may be to get sprint and run into the area to try and assassinate him (never hold down the melee button, mash it in case you just punch him. That second punch might kill him). I did this on the elites at the end of Winter Contingency, and Pillar of Autumn. Just make sure to find a place for cover after this.

There are multiple factors in your success in the campaign. Weapons, avoidance, strategy, and, most importantly, patience is needed to complete the campaign on your own.

Weapons: Keep a constant eye out for the DMR, Magnum, Sniper Rifle, Plasma Pistol, Needler, Needler Rifle, or Energy Sword, as well as heavy weapons in areas with heavy or aerial enemy vehicles. The Jet Pack, Armor Lock, Drop Shield (for its restorative powers), and Sprint are all useful armor abilities, while Holographic Decoys, Active Camo, and Evade are rather pointless.

Enemies:
Elites- best taken down with either a headshot from the Sniper or an overcharged plasma pistol shot followed by a DMR or Magnum headshot. However, on Zealots, it is best to pepper them with the plasma pistol shot until their shields are down. Stay away from them, however, for their kicks will kill you in one hit on Legendary.

Hunters- Plasma grenades, shotguns, energy swords, and needlers are useful for taking down the Hunters. Stay mobile when they are nearby and be wary when close for their 360 degree range of melee attack. If close, try to knock off the back armor with melee until the softer flesh is revealed. Or three sticks will suffice in killing one.

Brutes are best killed either by knocking off their helmets with a few DMR or Pistol shots, followed by a headshot, or by using a needler supercombine. Shielded brutes are best taken down with peppered plasma shots and then a supercombine.

Skirmishers/Jackals- easily shot down with a single DMR or pistol headshot. Shielded variants may need either a shot in the shield opening or at the legs for a second shot, or a grenade thrown just behind them. Beware of open areas with Jackal snipers.

Drones- best taken down with a needler rifle or a quick and accurate headshot from the DMR or Magnum. Use hit and run techniques to avoid taking too much damage with a large swarm of drones.

Grunts- a quick headshot with a magnum or DMR ends a grunt quickly, and simply one extra for helmeted variants. Beware of grunts with Fuel Rod Cannons (I call them Jesus grunts). They will snipe you in a second on Legendary. Also, keep Grunt Birthday Party on, as it can cause a AOE blast that can damage or kill other grunts.

For any vehicle, it is best to kill a turretman, then stun the vehicle and kill the rider without destroying the vehicle. Vehicles are invaluable, as long as you are careful.

Winter Contingency- A very easy level. Simply run straight from the start and ignore any cutscene or conversation. Run until you get to the first skirmisher and end it with a headshot from your magnum. Sprint through the basement and exit out of the far side with a small tunnel, popping a few grunts with headshots on the way. Stick to the far left and sprint as much as you can, avoiding combat. When you reach the little shack, run out of the exit and around to the left along the rocks and jump over the ledge. Hop in a vehicle and drive straight to the part where the marines are being attacked by two Spirit dropships, preferably passing quickly through the building occupied by skirmishers, grunts, and elites and the fort surrounded by water. Kill all enemies here, and then when you reach the new location, simply wait in the building until Kat’s done. After the cutscene, try to kill the elite with the DMR and do not approach, or he will flee and you’ll have to contend with him later. Fight through the hallways until you reach the final room. After killing the grunts, run down to trigger the sword elite, then retreat. Head up the stairs and wait until he attacks Jorge, then assassinate him.

Oni Sword Base- Not much strategy other than to keep a gunner on your vehicles at all times. Take this one slow, and it’s not too hard. Keep an eye out for the Sniper in the small outpost.

Nightfall- Stay silent at the beginning of the level and don’t kill the grunts followed by the elite with assassinations on the very first ledge. Run to the building on the right and move around and right through the doors. Sprint around the right side of the next area, dispatching grunts and avoiding elites if possible. Head into the building on the far end on the right, moving upstairs and out the door to the turret-mounted grunt. Kill him, then sprint through next area, picking off jackals and grunts. Run around the right and through the cave, avoiding all enemies. Ignore the rebels and sprint down the hill to the left side, using the tiny hump to hop up on the area. Simply turn left and continue the path, ignoring the waves of enemies behind you. At the area with the Covenant generator, pick off enemies on the bridge and disable the turrets and grab a forklift. Drive it to the gate on the left and park parallel against it, then hop out. If done correctly, you will phase through the wall and have a free escape.
Tip of the Spear- For the most part, this mission is rather straightforward. In the beginning, run up the left side of the area along the cliff to avoid enemy fire, then slowly backtrack and take down each Shade for a Rocket Hog. Drive forwards and until the AA Cannon is visible, then fire the rocket hog’s launcher continuously at the cannon until it explodes. At the building, kill off everything from a distance with the rockets. After besting the skirmishers outside of the building, hop up on the bar next to the staircase just behind them and then jump onto the platform on the right. Walk along this until you navigate out of the area, then head up the stairs. Grab a Revenant. When you reach two wraiths and another cannon, use a sticky launcher to kill the turret men in both and then get up close to finish them. Use a Revenant to blast at the cannon until it explodes, then blast off the Warthog on the bridge behind the cannon and use the turret to pepper the hunters from a safe distance. At the spear, hijack a Banshee in the safe zone with rocks between you and the spire. Fly to the top and patiently lure out each Elite and splatter them.

Long Night of Solace- No real tricks. Just be patient, especially in the room with multiple concussion rifle and sword-wielding elites, as well as the returning hallway after that encounter. KEEP A PLASMA PISTOL AND SOME HEADSHOT-CAPABLE WEAPON AT ALL TIMES.

Exodus- Before you reach the area with brutes, I recommend you stock up on needler ammo and pistol ammo. Kill the brutes with needler supercombines and the skirmishers with pistol headshots. Clear out the building in a similar fashion. Before activating the elevator, restock on needler ammo and then grab both DMRs in the area, one in the first room on the lower floor on the left and the second at the start of the upper floor. Activate the elevator, then run back to the entrance to the building. Kill the skirmishers that appear with the DMR and then take out the brutes with the needlers. The chieftan with the hammer will take two supercombines. Be wary of another chieftan charging at you from the building. Now, simply work your way back to the elevator much like the initial affront.

New Alexandria- Only one small tip here. When the notification for Club Errera comes up, activate both switches that activate the easter egg within the club. (simply google club errara easter egg for locations) One is on the roof of Club Errera, and the other is on one of the buildings surrounding the hospital. If you do this, only three brutes will attack you rather than two hunters and grunts.

The Package- Take this level slow and stick with the tank. Use it to destroy the AA guns from a distance, and carefully advance on the area with the Shade turrets, taking them out one by one. At Sword Base, carefully pick off the elites blocking your path and stay out of sight of the fuel rod elite. At the last area, choose one turret to stay near to activate whenever it goes down, but don’t worry too much about the others. When the Banshees arrive, use the Jetpacks to hijack them, and then use those to take down everything else.

Pillar of Autumn- At the beginning, leap off the cliff and sprint through on the right side to a trailer. Don't worry about the Scarabs in the next area, simply follow the path and watch for plasma pistols. When you reach the trailer park, take down the jackal snipers and the turretman in the wraith with the DMR, then dash down the right side of the area to the wraith to destroy it. Then, run up the hill, taking down skirmishers and grunts with headshots (grab as much needler rifle ammo here as you can), then carefully navigate the next tunnel. Drones will spawn here, so it is best to walk forward to trigger them, then run back to safety and take them out with the needler rifle. Be wary of the skirmishers towards the end of the tunnel. Grab a drop shield here. Now, run down the right side of the firefight area and drop a shield at the beginning of the last segment of the wall. Carefully grenade jump and crouch jump up onto the ledge, then dash into the building. Grab a Spartan Laser and take down both shade turrets and ghosts. Move to the lefternmost part of this area and traverse up a sort of bridge structure spanning the gap in the area. Exit left onto the roof and drop down into a hallway area. Move to the end and then go through the doorway, drop to the floor and go through the far door as quickly as possible. Kill the grunts and jackals in the next area, and then move down the right side of the area. Jump from a rail onto a barrel-looking object and then leap onto a ledge on the far wall. Deploy a drop shield and then crouch jump up onto the ledge in the right-hand corner. Move along the catwalk and then drop down behind the elites and run right around the stairs. If done correctly, there will be no hunters or skirmishers here. Now, instead of moving through the door here, break open the window beside the door and crouch jump in. At the top of this area, there will be a shut door. Carefully push two crates in front of the door so the door is fully blocked, then push a barrel upright on either side of the crates. Now, run back and touch the door to trigger the enemies, then carefully take down the grunts and jackals. If you move past the wall, an invisible sword elite will run out. Run back and wait for it to attack Emile, who will drain its shields, then shoot it in the face. Move up to the top floor and you should see an elite behind the blockaded door. Use a plasma pistol for his shields and kill him with a headshot, with minimal reaction. Eventually, you'll reach the area where waves of enemies attack you while Emile mans the AA Gun. Stock up on DMR and plasma pistol ammo in the building, then retreat to the wall on the stairs where you first entered the area. Hold out here, and be wary of shielded chieftans with gravity hammers and sticky cannons. Finally, fight your way through the final area with the elites, grunts, and engineer (no way around this, just be careful and take out the engineer first). Run upstairs to trigger the waves of phantoms, then run back down and simply wait around the stairs until you hear "Fire now, Spartan!" then run back up, hop in the Mass Driver, and immediately charge for a shot into the belly of that carrier.

And then you're done. Enjoy the final half-hearted survival level and the following cutscenes. Congrats.

The best weapons to use against the enemy on Legendary (always look at weapon details) and always take cover, VERY IMPORTANT

Grunts, Jackals and Skimishers: DMR/Magnum/Needle Rifle.
-Always aim for the head and in one shot, GONE. Though 2 for the Ultra Grunts (1st headshot knocks its helmet off, 2nd kills them) and Jackals with shields (If head-on, Target the exposed hand and when they are lean back from the first shoot, go for the head)

Elites: Plasma Pistol, or any Plasma weapon and DMR/Magnum/Needle Rifle
-Use the Plasma weapons to drop their shields with ease, Plasma Pistol will come in handy there as one hit overcharge will drop shields to 0. after losing shield, they tend to stay open for a second or two, quickly swap for the Headshot weapons and let them have it (really important, when an Elite charges at with an Energy Sword)

Brutes: Needler or Needle Rifle, Plasma Pistol/Weapons for Chieftains first. Plasma Grenade for Armour Lockers
- Don't waste time with the DMR or Pistol on them, they are thick-skinned and take 3-5 headshots to kill (Have to knock off the helmet first), they can use Armour Lock and ones with the Gravity Hammers strafe left and right when they charge. But their thick-skin doesn't save them from the Needle explosions, offload 8 Needlers Rounds or 3 Needle Rifle rounds and kaboom! The Brute is dead
-Use Plasma weaponary on the Chieftains first to drop their shields, than offload the pinky goodness into them
-Note that some may go into Armour Lock when attacked with Needles or any explosive, but don't fear, this can work to your advantage, if you have Plasma Grenades in your possession, throw one on him when he breaks out of armour lock and step away from him

Engineers: Any weapon
- Though rare and sore to you (If you played ODST and grew a liking to them). Engineers do pose as a threat because them giving temporaily Overshields to the enemy, Being slow moving and unable to attack, they are a quick to dispose off

Hunters: Any Explosives, Assualt Rifle or Shotgun
- Hunters are a bitch to kill and they are lethal as all in Legendary, best to take them on is by throw as many grenades as you can carry or If you have a rocket lanucher, Plasma Launcher or Fuel Rod Cannon pound them with it. And if they aren't dead but exposed, aim and attack their weak point, the back, by distance, controlled bursts or can go close (though not really recommended) But if you want go CQC on them, DON'T STAND STILL! stay mobile and keep the pressure on them, you stand still, and that spot will be your grave

Drones: DMR/Needle Rifle and big pair of balls.. or Assualt Rifle, Or just run!
These things are twice is worse because of their speed, if your a good marksman or they aren't swarming on you, pick them off with headshots. but if they swarm, Assualt rifle them. Though if you can't take the heat, RUN! and take cover for shield recharge if needed

Ghost and/or Revenant: Rocket Launcher, Plasma Launcher or Fuel Rod Cannon (DMR for Grunt controlled)
-Don't bother Hijack them, unless you got good skill and big pair, thats just completely suicidal. and the Vehicles are usually Elite controlled, try to use the Rocket Launcher, Plasma Launcher or Fuel Rod Cannon to deal with them and movement out in the open so you don't blasted or splattered. High ground always plays a good role for that

Shades: Rocket Launcher, Plasma Launcher or Fuel Rod Cannon (DMR if no explosive weapons) (Sniper Rifle comes in handy on Nightfall)
-Watch out for these, because the fire rate on these bad boys are extremely lethal. For general disposal, explosives fix everything. but no explosives, thats ok, Because they mostly manned by Grunts so headshot fix them up and as you progress to it, quickly use a grenade to rid off it before it gets manned again. On Nightfall, A full Clip from the Sniper Rifle can destory it, Shade, gunner and all.

Wraith: DMR and either: Granade plant, Melee or Hijack
Not most of a problem than the small vehicle counterparts but still a threat. First off is to kill the turret gunner so he can't get a beat on you (and he is lethal on Legendary) after he is gone, proceed to the Wraith. Strafe if he charges so you don't splatered (or use Armour Lock if you have it, to protect yourself from impact and Breaking EMP's it) and boarded it and use the following
- Plant a grenade (Both ends)
- Melee the ass end of it
- Melee kill the driver and Hijack the machine (Highly recommended for the final part of Exodus, but use caution)

When in doubt, use the environment around you to your advantage, Useless vehicles like forklifts, Fusion coils, Plasma Batteries, Fuel Tanks. These can take a good number of enemies when they explode, See an opportunity, USE THEM.

Also the use of Equipment is really important, The Bubble Shield is a lifesaver when injuried and no health packs anywhere, also good use of the Hologram is important as it can take the attention away from you so can either finish the covies or move to a different spot. Armour Lock has little use but can save you from sticks and Wriath mortars and charging

--Stage based guides--
Long Night of Solace: In this stage, the Covie polits are really talented at flying. But use the normal tactics to take down the fighters, But always execute barrels rolls and U-turns for combat advantage and so they can't get a decent hit if your getting tailed. NEVER go head on, unless you really have a death wish, hit them from the side or behind and when the Phantoms arrive, target them straight away, and pound them with missiles and go from different angles (Except front and below) and the minute the last Phantom is gone, the fighters will flee and that bit of the mission is finished

*Also Feedback is important, please give some to help this guide*

In my first Playthrough for this game I got this achievement, here are a couple tactics that seemes to work better.

For Grunts:
1) Any one headshot kill (DMR and Pistol) works wonders on them try getting each with a headshot.
2) If you have any plasma granades try throwing it at groups of this guys.
3) For masked Grunts line 2 headshots, one for the mask and the second for the kill, allow bloom to give you perfect aim.
4) this guys are not that hard, just keep enough distance to evade plasma shots and plasma grenades.
Remember killing grunts will provide you with one of the best tools, the plasma gun.

Jackals
1) same as grunts, line headshots, if they are shielded shoot their arms and then go for the headshot.
2) avoid rushing at a group of this guys they can kill you in no time.
3) Skirmishers are fast, but they avoid getting close to you, so try take them down with the DRM or neddler rifle.
4) before engaging a jackal with a focus rifle, try and check their general position.

Brutes:
1) Brutes are fast and strong so avoid close combat as much as possible.
2) they don't have shields which makes needler class weapons and one headshot kill weapons a must have for a confrontation.
3) they are hard to assassinate so don't bet your strategy on it.
4) Brute Heros are tough (tehy have heavy weapons and shields, try to put some distance with them, so you are able to evade their weapons, and always be ready to get a little close because they will try and regenarate shields as much as possible.

Drones:
1) keep in cover because they will drain your health fast.
2) pop and shut automatic weapons as they are to mobile to try and get headshots all the time.
3) they don't have much resistance but they are always found in big groups.

Hunters:
1)Hunters are slow, but can endure a lot of punishment.
2) is better to save you heavy weapons for this guys, they don't have shields and are big targets which makes it easier to get heavy impacts on.
3) always be cautious on their plasma shots, it is a one hit kill.

Elites:
1) The ones who will kill you the most, try always to isolate one of them.
2) extremely mobile and shielded, so try and lock on with the plasma pistol, and then go for a headshot kill
3) If you deploy their shields they will run to recover them, so keep at medium range.
4) power weapons work ok, but they might be wasted (they can take more than one sniper headshot)
5) with sword wielding elites, try and have places to jump or get behing to, that will save you a lot from being stabbed.

Vehicle combat:
1) keep your distance, you can take 1-2 hits on any enemy before they counter attack.
2) scout areas before moving to them, that way you can learn enemy positions
3) splatter works fine with most enemies, just don't get sorrounded or your vehicle will not make it.
4) AI drivers are awful, so you should want to drive the AI and line it for some shots.

Instead of a walkthrough, I offer a handful of skills and strategies I recommend you take with you into the breach. Legendary Alone is very hard, so you will want to bring all of your defiance to the Covenant.

The Odds Against You
Legendary Alone is a challenge. Very little sustained damage will drop your shields and grind your health down. A headshot from most heavy weapons will kill you instantly, as will most melee attacks by Brutes, Elites, and Hunters. A kamikaze Grunt that you just can't land a headshot on before running out of ammo can also easily kill you if they decide to run out from around a corner with two live grenades in their hands. To survive you need to be as deadly, punishing, and ruthlessly unfair as they are. Here’s how...


SKILLS:
Leading Shots
Perhaps the most basic shooting skill is the ability to tell where the enemy is moving, how fast they're moving, how fast your weapon's projectile can reach them, and then judging how far ahead of the moving enemy to shoot so that they are hit when they get there, preferably with a headshot. The Sabre and a select number of covenant weapons provide a displaced reticle indicating where around a particular enemy you should be shooting to hit them. If you have not been employing this skill, then it might explain why your multiplayer matches have been going so poorly, and it pretty much damns your chances at completing Legendary Alone.

Pacing Shots
Remember that the faster you fire your gun, the less accuracy your shots will have and the more likely you’ll miss your enemy altogether wasting precious ammo. When picking off enemies at a distance, try waiting for the weapon's reticule to shrink and prioritize greater threats, ideally when they're not moving. Also remember though that shielded enemies like Elites must take continuous fire to drop their shields just so you can damage them. If you have to reload, or they take the opportunity to hide behind cover, their shields will recharge and you’ll be forced to waste ammunition to drop them again.

Using Cover
While Master Chief may have blazed through the Covenant with a gun in each hand, you're going to have to exercise a lot more finesse here, particularly when it comes to evading enemies. Cover not only serves to protect you from incoming shots, but it also severs your enemies line of sight with you, allowing you to maneuver against them more easily. A squad of Covenant focused on one target can be completely exposed to fire from either side. Also; when the chips are down, your ammo's run out, you're on your last bar of life, and you're just beginning to succumb to insanity, sneaking up on and ambushing an enemy with a hijack or assassination can be very satisfying. Get creative.

Mastering The Skirmish
Perhaps the most valuable skill to learn in both the campaign and multiplayer, is what to do when you inevitably come face to face on foot with an enemy. As is traditional in Halo, skirmishes are much more complex than they appear to be. What kind of enemy it is, their animation patterns, if they’re armored, unarmored, or shielded, if their armor can be broken, if they can be staggered, if they can Evade, how close they are, if they can melee attack you, if their weapon requires charging, if your weapon's reload can be canceled, if they can kite you, if they can be stuck, if your armor ability is on cooldown, and even if they can be Assassinated are all important factors to be aware of and prepared for. A skirmish could be anything from tearing the armor off a Brute carrying an Plasma Launcher with the Assault Rifle, then surviving being stuck by Armor Locking before landing a headshot with the Magnum to Sprinting into the middle of an unaware Covenant party, Assassinating the Elite leader from behind, and then escaping into cover to headshot the Grunts and Jackals from safety. Knowing how to handle every situation safely, precisely, and quickly is the hardest skill to master in Halo. You can’t survive them all, but here are the tools that will help you survive as long as possible:


WEAPON SELECTION:
Here’s the deal. Excluding grenades and vehicles, you can only take two weapons and one armor ability with you. With such a wide selection, what do you take? Well, here are some suggestions depending on what you expect to face:

Grunts/Jackals/Drones/Brutes (unarmored)
Magnum, DMR, or Needle Rifle*. Having a staple precision weapon with plenty of ammo will be your most reliable tool against the Covenant. You will frequently encounter droves of Grunts, Jackals, their Skirmisher variant, and occasionally Drones (or “Buggers”), and they all have one vital weakness: They are almost always killable in a single headshot. Due to their frequency, it’s extremely advantageous to have a small precision weapon to deal out headshots when they roll out, the scope on these weapons also makes it possible to deal death from a safe distance. Needle Rifles are ideal because they have the largest clip of the three, their being Covenant weapons make them more common to find (particularly amongst Jackals), and their supercombine effect makes three shots in close succession a kill even against armored Grunts and unarmored Brutes.

Brutes (armored)/Hunters
Shotgun*, Sniper Rifle, Energy Sword. When it comes to armored enemies like Brutes, that’s when it’s time to break out the power weapons. You’ve got to put them down hard because unlike Grunts and Jackals, they don’t back down. This usually means picking them off with Sniper Rifle headshots, or getting down and dirty with a Shotgun for some close-quarters action as you’ll most commonly encounter them. The quick shoot & melee ambush is a favorite tactic, as most Brutes will succumb to two blows if not three after they’ve staggered. Hunters are a different story, as they are nearly invulnerable from the front, they can’t be Beat Down or Assassinated, and on Legendary, their ranged and melee attacks are instant death. Here it is preferable to try and sidestep their deadly melee attacks for chances to shoot them in the back, or more safely, sneak up on them while they are pre-occupied with another member of Noble Team and get in some Shotgun action. Alternatively, Energy Swords will do more damage, however they are much less common than Shotgun ammo.

Elites
Plasma Pistol*
They’re fast, they’re deadly at close range and long range, and worst of all: they have shields. When it comes to Elites, their name says it all. In terms of combat, their versatility and the consistently different environments leads you to encountering them in wildly different situations. Some have jet packs and very little shields, and can succumb to your DMR easily enough, some are invisible and carry Energy Swords (surprise!), while others may have a small army in tow and be toting a death-dealing Fuel Rod Gun without hesitation, and with a wide vantage point on the map. They have a wicked accuracy, reaction time, and rate of fire, and will gladly kick you in the face back to your last checkpoint. Frankly, there is no one right way to kill an Elite, your goal should not be to kill them in any particular way, but to kill them while expending as little ammo as possible, as their shields means you can find yourself wasting rockets or DMR ammo very easily and effectively damning yourself for future encounters. Keep an eye on their weapons, be ready to kite the occasional Elite with an Energy Sword, and kill them from a distance if you can, just dropping their shields can be sufficient enough for another Noble member to take them down. Perhaps the most effective, if infrequent choice of weapon to use against them is the Plasma Pistol. Overcharging a shot can drop their shields, making them easy prey, however higher ranked Elites will need more than that to be taken down.

Vehicles
Plasma Pistol*, Grenade Launcher, Rocket Launcher, Plasma Launcher, Spartan Laser
Enemy vehicles are even bigger damage sponges than what you usually face, so what you bring to the table should be equally as devastating. The Rocket and Plasma Launcher’s ability to guide their projectiles makes them great for reliably deal incredible amounts of damage to enemy artillery. However if you haven’t got a power weapon on hand, a Plasma Pistol or Grenade Launcher’s EMP could just land you free Banshee. Literally.

Miscellaneous Situations
Needler/Machine Gun/Plasma Cannon/Focus Rifle
Though not especially effective against any particular enemy, some weapons are just all around useful. Needlers are extremely effective against isolated targets with nowhere to take cover, and likewise, the Focus Rifle is valuable at long range so long as you can survive the period of exposure required to unleash the constant damage it deals. The Machine Gun and Plasma Cannon are detachable turrets you can take with you. While they may at first seem like painting a bullseye considering the decreased movement speed and required exposure to deal damage, they are a nightmare to the Covenant if you’re waiting for them at the end of halls, or the side of doorways as they trickle into sight.


ARMOR ABILITY SELECTION:
What armor ability you have HEAVILY impacts how you should approach most situations. You shouldn’t Jetpack into the vision range of snipers any more than you should go for that beat down if you can’t Sprint away from the consequences. Here’s a short list of how each ability will best serve you.

Sprint
The default ability, and probably the one that will save your life the most. You may find yourself quickly rushing up behind an Elite to assassinate him before your valuable opportunity for an instant kill expires, however you’ll most often find yourself fleeing into cover. Never underestimate the value of running away, “live to fight another day as they say”. Fleeing out of sight and then outmaneuvering your attacker is an extremely valuable tactic even in multiplayer. It really hurts when that enemy you almost killed but let get away appears behind you to put a knife in your back.

Armor Lock
Spartans will find very limited use for Armor Lock in the Campaign where the variables in skirmishes aren’t set in stone. Unlike other spartans, Covenant can often take more than 2 or 3 melee attacks to put down, and telegraphed attacks widely range in delay. The Covenant are intelligent too, and they will stop shooting and back away from Armor Locking spartans. If you have Armor Lock, it is best employed to survive grenades, kamikaze Grunts, explosive shots, and splatter attempts made by enemy vehicles. Alternatively, if you are in the company of an invincible Noble member, Armor Locking can potentially give them adequate opportunity to kill or distract the enemy. For most situations though, Armor Lock is not recommended.

Jetpack
Spartans will also find very limited use for the Jetpack, however moreso for it’s infrequent appearance in gameplay than lack of utility. The Jetpack is most useful for reaching otherwise unreachable vantage points on the map, as such it favors Snipers and keen users of the DMR or Needle Rifle. Jetpacks can be used defensively as well as a means to escape up into the air away from grenades, explosive shots, and vehicles attempting to splatter you. However open air is also the worst form of cover, and it should be taken care not to Jetpack into the vision range of enemies that can fire upon you. The Jetpack is particularly valuable against lone Wraiths, if the Jetpacker can eliminate the Wraith’s gunner, they can soar directly over the Wraith, safely out of range of their plasma cannon and then board it on their way back down. Due to the selective, albeit quite valuable nature of the Jetpack, it is only recommended for the most judicious spartans.

Active Camouflage
Despite popular perspective, Camo is still a very valuable tool against the Covenant. While true, the higher difficulties greatly raise the awareness of the oft-alert Covenant, being able to to stop moving and turn invisible as a particularly dangerous enemy walks past can mean the difference between life and death. Most enemies will not notice an unmoving spartan in camo, however they may face in that direction. The key is to never risk getting too close to someone in camo that they notice, moving patiently from cover to cover to minimize your presence, and to ALMOST ALWAYS CROUCH. Crouching while moving in camo ensures you’re moving the fastest you possibly can without disrupting your camouflage while also silencing your footsteps. A spartan in camo may be harder to see by an Elite, but not harder to hear, and consequently; moving at full speed may vary well catch the attention of a would-be victim. Camo is recommended in close-quarters on-foot segments of the campaign where spartans can get behind enemies most easily.

Drop Shield
The Drop Shield is an indispensable armor ability for two simple reasons. The first is that it can absorb a set amount of damage, allowing spartans brief Armor Lock-like protection. A quick Drop Shield can protect it’s user from a single Wraith shot, for example. The second is that it actually replenishes the health of any spartans in it, giving them that little bit of endurance they need to make it to the next Health Pack. This is useful throughout most of the campaign, and is recommended for spartans who are having an exceptionally tough time surviving it in large open areas. However it is NOT recommended for close-quarters where it can become a deathtrap against deadly on-foot troops that should be kited like kamikaze Grunts, Brutes with Gravity Hammers, and Elites with Energy Swords. It also will not protect against splatter attempts made by Covenant vehicles or Kat.

Hologram
Perhaps the most oddball and unreliable of the armor abilities is Hologram. Some enemies will pause and perform a double take when confronted with the Hologram, while others will ignore it. It can potentially reduce the amount of fire you sustain by providing the Covenant with a second target as you move to close the distance between them, however due to it’s unreliability and the extremely small amount of damage you CAN take, it is strongly recommended to take Sprint or Camo instead.

Honestly, I only managed to effectively use Hologram ONCE, but to be fair it was against the “last” enemy of the game. In The Pillar of Autumn, on your rush up to man the Mass Driver Cannon, you’re faced with multiple Elites lead by an Elite Field Marshal wielding an Energy Sword and a Fuel Rod Gun. At this point, ammunition is extremely low, and Assault Rifle and Needler ammo is largely wasted on their strafing behind cover. So it’s assassination time! After carefully dispensing with this underlings (running out of cover, knifing one, and then running back), all that remained was the Field Marshal who has a powerful vantage point from the second floor of the room, and only one way up to him. After some tense deliberation, I decided to grab Hologram, and when his back was turned, rush up the stairs around the corner into crouching cover. The Elite unsheathed his Energy Sword and rushed my position just as my Hologram ran out to the top of the steps. He fell for it, turned his back to me, slashed at my Hologram, and I congratulated him with a knife through the skull. VERY satisfying.

Earning this Achievement will also earn you these 12 achievements:













Additionally, you can earn any of these 22 optional achievements on your Legendary playthrough:

Tip for the MAW CANNON at the end, shoot as much as u can then just when your about to die, hold X and jump out and go behind the cannon so u dont get shot, then wait for a radio call saying 'shoot it in the center/bottom pink bit' then jump back in and shoot the big ship before u die. can be done even with the lowest possible health.

is how i did it...

on the package mission if you have a lot of time on your hands you can glitch your spartan behind an ammo cache during the firefight part of the mission, you should take off the automatic shutdown for you xbox if you do this or just use bands on your controller, the ammo cache is on the furthest right against a wall when facing where all the hordes of enemies come out

Just watch this video. It is a speed run of Legendary solo with no deaths in around 2 hours and 30 minutes. Very helpful and very fast.

I second the advice on using the plasma pistol. Unlike Halo 3, this is a very useful weapon on Legendary. In the latter stages when you're surrounded by enemies with shields, it's absolutely invaluable - better for taking out elites than rockets or a fuel-rod cannon.

Here are some quick helpful hints. Don't be a lone ranger (let the A.I. help you, they will actually kill people in this game unlike some other games such as homefront), go for head shots, avoid enemies if possible (ex. when your driving the mongoose to the pillar of autumn), conserve you grenades for large groups of enemies, and save the plasma grenades for large enemies. Always more for cover because the enemies will destroy you with ease on this difficulty.

If there is one thing that I've learned from torturing myself for two days in a row trying to get this achievement, it is don't rush the enemies, because then you'll either not be able to complete the mission because an elite is shoving his plasma rife up your ass multiple times; or you'll get that with a checkpoint right in front of him. So, the moral of the story is, just pick off as many of the strong enemies as you can with your weapon you can aim with, and then rush the weak little grunts.

If there are the dynamic duo's (Hunters) around, take out the weaker enemies, then run around in circles around them, because they don't turn that fast; or they'll focus on your partner, and since they cannot die unless it's scripted, you don't need to feel guilty about them getting a ball of plasma bigger than them launched into their face. Now after The Hunters are focused on your partner and or are facing the other direction, then shoot them in the back as much as you can, until they become aware that you are in fact shooting them and turn around. Then you repeat the same sequence until their hearts stop beating.
