GLITCH WARNING!!
****UPDATE!! As of 12/27/2014, the glitch may have been fixed on the server side of this game finally! If you get this achievement despite glitched Assault Ops, please let us know!!****

This achievement can glitch, particularly Assault Ops for A-1 going over the correct count and not completing.

Enemies, Turrets, and Vehicle Descriptions:

I wrote this solution to be used with the Ctrl-F function to easily find whichever Op you are looking for. Simply type into the Ctrl-F search box whichever letter, number, and letter code you're looking for!(i.e. A-1a, D-2c, E3-b, etc)

Enjoy!!

This guide is super useful.

Here's a few extra pointers I've got for E-1, if they'll help:

E-1a: the drones are the flying things (I thought it wanted grunts and got angry and thought I wasn't getting credit, ha). Follow the path, killing everything up to the wraith, clear the area with the wraith and get out of it and head straight south, then a little east. Near the grenades there, at the opening, a group of 6 drones should fly up. Bait them back towards the wraith and waste 'em. Two runs tops, you can even try to avoid killing the first group of drones on the main path before you get to the wraith if you want but it's not necessary.

E-1c: You can bait the stealths and as long as you're not facing them they should follow you all around the level. I would head left from start and let the first one kill my team, then lure him up to the first turret. Make your way up to the 2nd turret, jump in it and waste everything with the turret, then you can lure at least a few more to this turret. Alt you can just re-kill the first stealth and restart. Easy.

Thanks! And I added clarification, I can see how that could be confusing if you just aren't thinking about it smile I really enjoyed writing this up and it helped me when I had to do it all again for my 360 glitched save. lol! The Grizzly is simply ridiculously powerful. Wish it was in the Halo campaigns.............................. headspin

For C-5c "Special Delivery" the drones usually tend to go up where the engenieer is working, so wait until they all gather up and start throw the granades. If you kill that early brute, you get 1 more plus 3 in the left so is not that hard, it just take so many replays.

PD: Awesome guide, I was doing this by myself until I found this in Operation C. Great great work.

It's terrible, possibly the worst one. I enjoyed playing this game so for D-4 I just tried to relax and see how efficiently I could exterminate the Covies in D-4, and then take a run at the Jackals, aiming for a high score every time. That helped make it not so boring. You can get some amazing kill streaks going on D-4. Don't forget to use a damage upgrade though! If you think about the score with Jackals as a bonus, it'll finish before you know it.

For C3, it was kind of a crapshoot as to whether or not the ambush would happen, so on a lot of runs elites would be scarce. To compensate I spend the 800xp on a damage boost to get more mileage out of my magnum, then instead of completing the mission I would let time run out and retry to keep the damage booster going. Once I completed all assault ops I completed the mission to lock it in.

Also worth noting that when going for the elite minors that the needler counts as a pistol, so I would scavenge one so I could save my magnum for the elite majors.

I've updated both Extra Credit solutions to reflect your tips.. the Needler tip especially, and I completely forgot to put the tip about restarting/deliberately failing missions to keep your special mission boosts. Thanks for reminding! About C-5c, you've pretty much described exactly how I said it in the solution. I'm very impressed it only took 6 runs though! That's about 2 drone kills for every plasma, nice! I've edited the number of playthroughs to reflect that.

Great solution! It was very helpful.

I also highly recommend getting the damage boost upgrade when going for these because it makes them much less annoying and you get the XP you spend back when you complete the challenges for that level.

I had 20k XP before I started grinding out the ones I was missing - definitely pay the 800XP for damage boost as it makes life a helluva lot easier.

I have 71 completed - 19 to go...

I might add to the solution the easy way to gets lots of XP... replaying the first mission over and over getting a gold gives you almost 1k each time I think it was, and it's really fast.

I'm now on 89/90 but only registers 87/90 as the first mission has decided to glitch itself despite me not having played it since day one...

It has better unlock once I kill those bastard jackals. I may throw my Box out a window otherwise.

E2-B. There is a stun blast armor ability in the left middle of the map that helped me greatly with this one. They are very hard to hit otherwise without killing your engineer.

Great guide!

Im sitting at 87/90 with all special ops complete. Some in A-1 and A-2 say 38/20 or 138/2. Should I use xbox one fix #2 to try and see if the achievement will pop? Do I need to remember which ones are saying that and redo those three? Thanks for your help!

By phrozan on 08 Sep 2014 20:07
Go with Fix #2, however, first!! Go through all your Assault Ops until you find the ones that are glitched: you can easily tell because it'll say how many are completed for each mission. Go through, find all 3 that are glitched, and if no others than the first mission or two, do the Fix. If there are some other random ones, see if you can complete them first. Let me know which ones are glitched for you... dance

Yes. I might remove Fix #1, as I think it does more harm than good. With Fix #2, it should be impossible to lose any information, since it takes advantage of the Xbox One's most recent save abilities.

Spartan Assault: Update needed: Kill 50 Grunt Majors with Grenades
Normal--Very Slow. Another annoying one that requires restarts. The only Grunt Minors on the map are around the Gold Elites at the top right of the map.

Description mentions Majors but your guide points to Minors, Also may help to state what color the majors are. Thanks

Seems like they've patched in a compromise for this. The achievement unlocked for me today at 89/90 ops completed; the counter for the third assault op had glitched, and was currently at 48/3.
I wasn't looking forward to having to try the workaround, as I had got the game via GwG, and couldn't launch it while offline. Thankfully I didn't need to. \o/

Good tips Chucklestyle and peeveen!
I'll try to add appropriately with credit.
Looks like I should add a quick enemies description just to make sure no one's too unclear. smile
Question for Chucklestyle, are you sure those six drones weren't the same as the 6 drones that fly up at the start? I found that I would get drones near the start, and those may be the ones I would shoot at. If there are indeed an additional six you can get to spawn after reaching the wraith, that would help quite a bit.

peeveen: NICE!! Did you notice whether you had an update for H: SA? I'm not sure if they fixed on the server side finally, that would be great news!

To get the enemies on mission C-3 to constantly spawn, you need to destroy 4 of the wraiths and then run to the end of the level, enemies including the Elite Majors will come pouring through the light wall. Hope this helps anyone who see's this.

Here's a guaranteed way to get e4-c done in one go: when you nab the ghost, go up and to the left to kill the lieutenant who's next to a shade, and a cliff. Drones will keep spawning out of that cliff and you can just sit and farm them for about 30 seconds, and voila! Assault OP complete

By Smiththedude on 05 Feb 2016 11:27
Question :-) How long did you wait for those Drones(was it possibly your 2nd playthrough and you didn't have to wait long to get enough kills)? In my experience, the Drones from there only spawned a certain number(maybe 20?), it just looked like they kept coming unless you waited long enough. Can you let me know please, then I can add a note to all 3 solutions. :-)

Not sure why it is, I have some memory problems, but I can picture that area of the mission right off. LOL Halo's just too much fun!

For F-3c (Kill 60 Elites with Frag Grenades), my trick is too shoot at the elite a little so he runs to cover, once they are hidden behind cover, they never ever dodge your grenade, so it is a 3 kill every time you restart :)

First off great guide, this REALLY came in handy getting this achievement. Only suggestion I have is for Operation F-2b, maybe clarify the starting tank is Grizzly and the tank further up is the Scorpion. I just skimmed over the description and didn't realize I was in the Grizzly tank and none of kills were counting.

By I LUNCHTREY I on 17 Jun 2014 21:04
For C-5c, I would start the mission, kill the grunts and grab the plasmas on the left, jump in a shade turret to kill the brute, grab his plasma grenade, then head down by the engineer and hold LT to aim my plasmas at the north opening. I would toss a plasma as soon as the first drone got in its circle, and repeat with the rest of my 4 plasmas. If any drones were still alive I'd gun them, then run left to where the grunts spawn and let them kill me. Retry and repeat. Only took me 5 or 6 runs.

By Chucklestyle on 28 Jul 2014 00:57
Yes, they are very hard to hit--I thought about using the stun blast, however it's recharge time coupled with not having the sprint boost makes it a little slower than just aiming at one spot where the drones aren't yet, and throwing your plasmas. I found that the drones almost always moved just in time to get hit by the plasma if you throw it where you've seen them go.... a little confusing though. smile

A-1 Kil 3 grunt minors with frag grenades shows 81/3
A-1 Kill 20 elite minors shows 38/20
A-2 Destroy 2 shade turrets with plasma grenades shows 190/2

All others are completed as it shows 87/90 this is the only thing i think would work. Should i do fix number 2 and then these missions and report back?

Great guide! Was very Helpful! Just wanted to say that with the Scorched Earth OP on E-2. It makes it a hell of a lot easier when you pick up the stun ability. Stun them, aim your grenade on them and voila. 3 kills every time. It's located next to the plasma repeater locker a little bit down from where you start and on your left.

D4, 20 jackal kills is just insane, the suicide grunts at the end kill them, you only have a matter of seconds to kill them and then the mission ends. ON TOP OF THAT!!! you are limited in the amount of room to move since the damn elephant is in the way. 343 was not thinking clearly when they came up with this challenge. Please someone post a guide for that part.

On D4 you want the ability that lets out an electric pulse to stun people. Wait for the suicide grunts to get some separation from the jackals, and then stun everyone. Then just shoot jackals. It still takes forever, but you're more likely to get the kills at least.

Just to add on what GoBlueFiddler13 said, if you buy the Damage Booster (800 XP) it helps alot you can get 4-5 Jackals at a time, when you killed about 4-5 if your fast you can hit the restart mission, doing this will keep all kills and you get to keep the Damage Booster, did this in 10 mins

E2 is pretty bad the elite majors don't go down with just the incendiary grenade and they dodge them all the time if you do get them down, I think the only ones I've got on them were when I let them run past me and my spartans shot at them and I chucked a grenade to kill it.

For anyone struggling with E-2; kill 10 Elite Majors (red elites) with incendiaries, from where you begin the mission, go directly south and you will see 2 Covenant plasma containers (ones that are highly explosive), next to them is a Covenant weapon crate holding Plasma Repeaters, in between both of these is the armour ability that stuns enemies. It will make this a minor task of waiting for the elites to come. You start with 3 incendiaries so use 1 on each whilst they are stunned. Restart mission and repeat.

EDIT: According to Mathguy this is now resolved; It should pop when you launch the game; Let me know if it doesnt!

This isn't so much a solution as it is information.

For anybody who has played Spartan Assault on WP8 or W8 this achievement is currently glitched and unobtainable as confirmed by several members on Halo Waypoint Forums.

This is due to the game synching your information across all platforms and it marking all/some of the challenges as completed which means it's physically impossible to get credit for completing all the missions as required by the achievement.

Rest assured though, it seems 343 are aware of this issue and have passed it along to their support teams so hopefully a fix will be put in place for the achievement to unlock correctly over the next few days/weeks.

I will remove this "solution" once the achievement has a confirmed fix.

EDIT: Comment from 343 on the 3rd Jan:

"There is a known issue with the Extra Credit achievement that is under investigation. We know this has been a frustrating process, but we do have a team working on resolving this issue. "

It is being worked on folks; Just a matter of being patient.

Doctor Arc, have you played 5 co-op missions on X1? Because the X1 version uses the Achievement Progress system, none of the achievements automatically carry over from the other versions. You must redo the requirements of each achievement to increase your progress percentage.

The only semi-exception I know of is 117. You must replay each mission on X1, but you don't have to get Gold again. Just replaying a mission will make the 117 progress go up. Perhaps Dynamic Duo is the same way, but I unlocked that before the 360 version was released.

So my advice is to replay all 5 co-op missions on X1. If you don't unlock Flooded and Dynamic Duo, please let us know your progress percentage on those. Flooded actually has a positive glitch where it will unlock for doing any 5 missions, even with repeats.

The issue with Extra Credit is that there is no way to redo an Assault Op on X1, so you can't make the progress percentage go up if you've already done the Assault Op elsewhere.

Here's another hopeful post by bs angel.
Wanted to provide a quick update: We've identified what we believe will be the fix for this issue and are currently working with the Xbox Live team to schedule a Content Update (the Xbox One term for Title Update). We're hoping to release it this month but nothing is final yet. Will let you know once the date is official. :)

Please remember, you can see the general status of Spartan Assault bugs in this thread:

https://forums.halowaypoint.com/yaf_postst235212_Spartan-Ass...
Going to that link shows
Bug: Extra Credit Achievement
Status: Fix identified, working with Xbox Live to schedule release
Description: For players who have completed or made progress with challenges on another device, no progress is being shown, despite challenges being complete.
So this should fix Glitch 1, as I describe here. But no mention of Glitch 2. I'll follow up.

So since I never played it on WP or Win8 then I should be able to 1k it without them fixing this correct? Because it won't sync any data from any other platforms...

By LifeExpectancy on 24 Dec 2013 17:12
As I understand the situation, it should work for anyone who hasn't played WP8 or Win 8. You could check the Achievements app to make sure. Each Assault Op should show a 1-2% increase in your progress. (Really 1.11%, but the Achievement app only shows integer percents.) You could also check on TA, which gives numbers like 15/90 instead of a percentage.

If I understand this correctly, if someone had 1/90 done on Win 8, then did the rest on X1, their progress would be at 98.89%. So even one Assault Op done on another platform will glitch your achievement.

I don't want to promise but yes I honestly don't see why you would have a problem, the issue comes from not having all the missions to complete, because you're playing fresh you shouldn't have that issue.

Just to add to Revolver Ned's comment: If you play X1 first, then you should only need to play A-5, B-5, etc to get the Finish Mission A, B, etc achievements. That's how it works if you play Win 8 and then WP8, or vice versa.

Parish7, I have heard of this happening before with various achievements in various games. The X1 achievement system currently has a bug where the achievement progress is 100%, yet it doesn't unlock. This is an OS level bug. From your experience and other reports, the achievement usually unlocks later, but I have not heard of any way to trigger the unlock.

Extra Credit is finally fixed! The achievement unlocked as soon as I got to the Main Menu, like it does on 360.

Well, at least for Glitch 1 was fixed. I'm not sure about Glitch 2 (where some Assault Ops can be over-completed, like 100/3 Grunt Grenade kills).

The game was silently updated overnight since I use the Instant-On mode. A friend who does manual updates let me know it had updated. And here's a post announcing the update.

I've disconnected my wireless, deleted my console save, and started it up only to be asked about the license to the game or whatever it asks you when you don't have the disc. It wouldn't let me play without being connected or having a prior save. I deleted it and tried to play while connected, stopped the sync, and it still wouldn't let me do the "fix."

Did you "buy" it via Games with Gold? I think you must be online to check to see if you still have Gold, since the Xbox One GwG's are supposed to deactivate if you let your Gold expire. I purchased the game back in December, so such a check isn't necessary on my console.

So it may be that the workarounds won't work for those who got the game via GwG.

I also wanted to verify that you are experiencing the Counter Glitch. What do your A-1 Assault Op counters say? Someone thought it might have been fixed for new users back in the Spring, but I can see from your Service Record that you didn't start playing until June 13.

Phenom, I suggest you post your experience in this thread so that 343 sees that this is still an issue and that the workarounds won't work for you.

Phenom, this player was able to use one of the workarounds, even though he also got the game via Games with Gold. Perhaps the newest System Update fixed the licensing issue. I encourage you to try again and let us know what happens.

If you own the 360 version, the fix at the bottom of this solution sounds like it fixes the stats. It may allow you to unlock your last One achievement.

I designated my xbox one as my home xbox and it worked. I now have the achievement and it should reflect on this site in the morning. Awesome.

And now it is unlocked - not sure if it was playing the first mission again, completing a weekly challenge or neither.

Not that the game notified me. I found out here!

Just to confirm, doing a weekly challenge also won't work. That was the trick for popping this on WP or Win8 if you had already completed the other. Doing all 3 weekly challenges won't work either.

I've played previous versions and it just glitched on me on XB1...first Ghosts with this kind of glitch now Halo...youd think after all these years developers wouldn't have achievement problems like this.

I would also like to add that I have NOT played Halo: Spartan Assault (Win 8). I only have the Xbox One version. Today, my assault ops became glitched. The game was saying I did not complete the first two ops on A-1. The progress bar said 322/3 Grunt Minors killed with Frag Grenades and 244/20 Elite Minors killed. Even though I had previously completed these ops the game was registering them as incomplete. HOWEVER, I continued to complete all Assault Ops and when I finished the last one on F-5 the achievement popped, even though the game said 88/90. Just posting so if anyone else has this happen to them, fear not, there may be hope!

Yes, the 360 version will unlock immediately if all 90 Assault Ops have been done previously. According to this post by bsangel (343i Community Manager), the H:SA team made sure this would work due to feedback on the X1 issue.

Also, the post says, "Will let you know once there's a window for pushing the fix out to the Xbox One version (requires a Content Update, which is a bit of a lengthy process across our team and Xbox's)." AFAIK, this is the first confirmation that a fix is coming.

I don't understand the delay either. As I argue here, the Counter Glitch should be fixable on the server side. A server side solution would fix One and 360 simultaneously. And there would be no need to coordinate with Xbox Live for a TU since the game itself isn't changing.

^ You should be OK. The Feb 19 update patched the game so that if the counter is 90/90, Extra Credit will unlock immediately at the Main Menu. Apparently they didn't fix the achievement progress tracker though, so those who have played on other platforms will still be off until they reach 100%.

You should check your counters for the A-1 Ops Warm Up That Pitching Arm and Rookie Target Practice. Those are the missions that can over-complete and then cause you to be stuck at 88/90 or 89/90. Someone posted that the counters seem to have swapped, so even if you're careful, it might glitch. I've not heard of issues with A-1 on Win 8 or WP8, so it might be safest to complete the Ops there, then not touch A-1 at all until you get Extra Credit.

Still asked me for my license. Maybe my system isn't updated. Though it says no updates available.

Phenom, are you playing on your Home Xbox One? I've learned that Games with Gold will not work with disconnected Internet on a non-Home console. Here are instructions for setting a console as your Home console. Hopefully this lets you use the workaround.

Just a tip.

If you want to make this achievement for Xbox One, Xbox 360, Windows 8 or Windows Phone (In this case you need to choose Windows 8 or Windows Phone to do the challenges, in case you do all the challenges in Windows 8 and start the game in Windows Phone, the achievement will remain unobtainable, or contrariwise), you need to do all the first challenges in WP or Win8. You're going to ask me why? I'll tell you why, this achievement for WP or Win8, it is only necessary to do 75 challenges to the achievement. Already the version of Xbox One or Xbox 360, needs to do 90 challenges.

In case you do all the challenges on Xbox One or Xbox 360 and start the game on Windows 8 or Windows Phone. This achievement will become Unobtainable. Because there are no more week challenges, which made the achievement possible.

But if you do all the challenges on Windows 8 or Windows Phone. Yes, you can still do that on Xbox One or Xbox 360, because when you connect your account, you still need to do the rest of the challenges, which would be the 25 remaining.

I made a video, and as I show in it, the achievement of doing all the challenges, appears with a percentage to be made.


Second tip.

I can confirm, if you have only 1 remaining challenge, you can win the achievement for both the Xbox One and Xbox 360. Basically you need to join on the missing map for your last challenge. You need to do this on both platforms, after you have join the match, I recommend doing it first on the Xbox 360 and then on the Xbox One. You can watch my video for no error.

Halo Spartan Assault - Crédito Extra (Solución)

El logro consiste en realizar 3 desafíos en cada misión del juego, por un total de 90 desafíos. El problema es que para la mayoría de los jugadores dicho logro se queda bloqueado, incluso al completar los 90 desafíos. Esto jamás fue solucionado pero yo encontré un solución que me funcionó:

- Borrar tu partida guardada.
- Desconectar tu consola de internet.
- Jugar la primera misión y realizar los 3 desafíos (o el que tiene bug).
- Cerrar el Juego.
- Conectarte a internet.
- Iniciar el juego.
- Cancelar la sincronización.
- Te saldrá la opción de elegir entre "Datos guardados localmente" y "En la Nube".
- Elegir datos locales.
- Ir al apartado del juego "Logros".

Si hiciste todo bien se habrá arreglado el error con las partidas guardadas y saltará el logro.

2021 it pop
If ANYONE has this problem

Example: 89/90
Example: A-1 Kill 3 Grunts with Frag Grenades. I got 99/3.

Step 1: Go to >Settings >Network settings >Go offine.
Step 2: Oven the Game >Press cn_start >Manage game and add-ons >Saved Date >Delete All >Delete All.

Step 3: Load the game up and go and see >Assault Ops. You Completed 0/90.

Step 4: Play that mission that is buggy for you for Example: A-1 Kill 3 Grunts with Frag Grenades.

Step 5: When you're Finished complaining that CHALLENGE Kill 3 Grunts with Frag Grenades. Go see your Assault Ops it would say you complete 1/90.

Step 6: Go to cn_guide >Settings >Network settings >Go online.
Then go back to the game that should pop! or Play that mission again.

I hope you would get it.

Each of the thirty missions in the Single Player Campaign has three specific Assault Ops, or challenges, that must be completed for this achievement. That would mean there are a grand total of ninety challenges to be done, so as I’m sure you guessed, this is where most of your time on the game will be spent.

These challenges are very grindy, and most of them aren’t even difficulty. They are simply tedious and annoying. They range from, “Kill x amount of Drones with a Plasma Pistol” to “Destroy x amount of Wraiths with a Grizzly Tank.” Overall, you’ll need to grind all of them out and take note, that if you complete an Assault Op mid-mission, you can quit out of the mission and your progress will still be saved.

You can view your progress for each Assault Op in the Main Menu, and for a simple checklist of all ninety, consult THIS LINK.

For this you'll need to focus on finishing the 75 mission-specific challenges, 3 for each mission in the game. The requirements can be found by looking in the challenges section in the main menus. In general, they range rather drastically in difficulty and the amount of time you'll need to spend doing them, so you'll want to look at them early on and try to take them out while you go through your playthroughs and try to get gold on all missions.
