Mortal Kombat

on level 300 start out like GeorgieVaz said above. pick sub-zero and spam the Y,Y,Y, combo, and freeze. now if your anything like me, you've failed a-lot on this level. you lose a lot of health on goro press start and retry. now this is where i'm going to tell you to STOP!!!

no matter how bad you're losing do not retry in the middle of the match. sounds stupid i know.
after 5 losses you notice after every win, you gain a little health back. almost so little you can miss it.

after about 10 losses, you gain 1/2 your health back after a win, & goro doesn't turn invulnerable before every attack or at all anymore. also by this point they aren't beating you down to the point that you can't move.

after 15 losses, by now i was making it to shaokahn every try. goro is a push over kintaro just jump Y,Y,Y, freeze repeat. for mileena a found dropping the freeze all together & dashing forward Y,Y,Y worked well, the same for shaokahn. (jumping over hammers as needed)

so. i know i suck i writing guides, but i use them enough i thought i should try & give back a little. hope it helps

I had to share my input on this one. I didn't try any of these other methods but I beat challenge 300 in about 20 minutes using Sheeva. The key is to not hit start-retry in the middle, or at the end, of any fight. Just lose for a while and keep retrying after your are dead. The difficulty goes down dramatically as continue to lose. I'd say around after 15 losses or so everything gets much easier and all I did is spam the down, up combo from Sheeva. After you kill each player you get what little life you lost back. Seriously, trust me, keep practicing while your losses rack up and by the 20 minute mark you can do this very easily.

The toughest ones to beat are 269, 275, and 300. For 269, you'll need to troll Stryker's gun while staying as far away as possible from Shao Khan. Timed jumps are required when he throws his hammer. Don't bother ducking from them as you'll get hit anyway. For 275, I primarily used Ermac's teleport/uppercut combo while throwing in a few force lifts after the teleport to gain a better combo. Didn't always work as timing is everything. For 300, I used Sub Zero. Against Goro and Kintaro, just jump in with a front punch and hammer the Y button a few times for his combo. You might be able to troll the combo if you can get them cornered. I managed to get to Mileena without getting touched. Mileena is tricky because blocking will be disabled for much of that match. Just freeze, jump punch, YYY combo. She can be a problem but takes more damage than the first two. When you finally get to Shao Khan, work the same strategy as Goro and Kintaro. Freeze if you can and jump in with the combo. Take advantage of their taunts by acting quickly. This cheevo was satisfying to get.

This is For Challenge 300

To make this really simple

Character i used: Stryker

Reason why at Shao Khan All you have to do is spam the Gun and jump over the hammer attacks when he does them.

Goro:
For the first part Goro I upper cut and used my gun from far watch out for his jump but if you spam u can get him stuck and he will not be able to attack

Kintaro:

He was a tough one this how it went Step back and use your gun but when he jumps dodge his attack and upper cut him and then spamm weapon there is a chance he can get your with the fireball but block incase of fireball.

Mileena:

This one was hardest what i did spamm the gun and block when she teleports i managed to get her stuck and she kept falling back from the bullets. Took me a few tries but i got it

Shao Khan

Remember the challenge with 3 Shao Khans well we going to use it the spamming the gun from far range. Move back and stay back at all times and spam that weapon like no tommrow. Remember jump over the hammer throws ans if you spamm the weapons he wont be able to hit you sometimes he might hit but youll be ok.

Stryker Gun move is: Back, Foward, X
Also put use to the enhanced which all you have to do is hold RT with the following gun move.

Note: Pay attention to your bar can help tell you enchanced bar is up.

After this achievment and youll feel the relief of a Challenge well done.

Pointed out by x InSoMniA o Might want to add that if you die 15 times and hit retry when it gives you the option it makes it a lot easier and you get half of your life back after each enemy. x InSoMniA o
Ty for point that out

Found this footage on youtube of 300 being done with scorpion... looks super easy. I thought one of the more difficult challenges was beating cyrax, sonya, stryker and jax all with kano. I hate kano!!!

I made videos for the 3 hardest challenges 269, 275, 300.

For challenge 269 - Just spam stryker's - Back, Forward, X move and try to stay away from Shao Kahn and when he throws the hammers be sure to jump over them.

For Challenge 275 - In this one just spam Ermac's - Down, Back, B teleport move as soon as Goro is about to attack or taunt.

For Challenge 300 - This one is impossible to do in the first couple of tries. Every time the player loses the challenge gets easier.

For this I used Ermac and just spammed his - Down, Back, B teleport move followed by a punch and an uppercut.

Mileena is probably the hardest fight here. When she does the teleport move hold down and try to do an uppercut you should always catch her with it.

I realize that this maybe a big "duh" to most of you but one floor I was stuck on was 101, where you are playing "back to back" with Mileena and Baraka...I was hitting the wrong buttons for the wrong enemies until I noticed that the enemies were wearing two different colors of shirts, the ones wearing black are the ones you need to hit with the "aerial attack" and the ones wearing beige/tan are one ones you need to hit with the "ground attack"..........hope this helped someone who needed it....

This is for Challenge #269, and #275. In my opinion are much harder than #300.

I finally got this achievement after trying for quite a while.

Challenge #269-Spam the living hell out of Stryker's pistol from as far away as possible. This is the best way to beat him. Sometimes he will still get an arrow throw away though so be careful. When he throws his hammer you can try to roll under it and grab and throw, but for me it was too damn hard so I just jumped over it. (The timing is tricky) After he throws his hammer try to get in close and do an uppercut or roundhouse kick, and get back out quickly. If you get frustrated just keep with the pistol fire and eventually you should beat him. Also I would suggest try saving your X-Ray as long as possible for when you really need it. I cannot stress enough about the pistol fire. (Back, forward, X) It will take you a while with many defeats, and you thumb will be worn out but it is the best solution.

Challenge #275-Goro is a real pain in the ass. You have to use Ermac so get familiar with his Force Lift, and Force Push. If you time it correctly you can do them one right after another. Be careful because he blocks all the time. When he jumps, it will affect you even if you are not close to him. I suggest running in for a uppercut, or roundhouse kick, then Force Lift followed by Force Push, and then back away quickly. Stand there for a second or two and let him make the next move. It seems that most of the time he will be confused as to what to do because you are so far away from him. Once you recognize his pattern of moves you can really dominate him. Keep jumping and work your way towards him and give him a good uppercut, and more of the Force and you should beat him. (Sometimes he blocks everything, and becomes almost unbeatable. If that happens you just have to chalk it up to a loss and try again)

Good luck and I hope this guide can be helpful to you.

To beat floor 300, I chose Ermac, and used the same technique I used on floor 275. That's the one where you have to fight 3 Goros in a row on a single life bar. The technique is to jump away from the opponent and, while still in the air, do a Force Port (down, back, B). Just repeat that over and over again.

On floor 300, I used that method to beat Goro, Kintaro, and Shao Kahn. For Mileena, I mostly just did uppercuts and jump kicks.

This is another solution for Mission 300. I didn't look at any of the others when attempting this because I'm kind of arrogant and believe in my fighting-game capabilities, but anyway here's my advice for anyone stuck on this:

The character that I chose to beat everyone with was Liu Kang, not only because it's fitting to have an end battle w/ him and Shao Kahn but because he has a few moves that are essential for this mission.

The first one being his X,X,X combo which you can follow up w/ a kick: B and an uppercut. If you use this combo and uppercut attack, you can get a flawless victory on Goro pretty easily. Whenever he's about to get back up jump in his direction before he gets fully vertical and kick him so that he doesn't block all of your atacks and your combo doesn't get broken.

So again, for Goro:
Combo 1: X,X,X and follow w/ an uppercut. Do not waste your X-Ray attack. You'll need it for Mileena.

Now onto Kintaro:
He's similar to Goro but a bit harder. For him, I found it easiest to jump behind him and land combo 1 and if he blocks it or hits you w/ a fireball, counter w/ a leg sweep. (Down + Back and B) also learn how to spam the bicycle kick or fireball. The bicycle kick has a pro because he can land a few hits even after Kintaro blocks. The con is that if he's not staggered, he can land a powerful combo or X-Ray attack on you since you're exposed. Timing is critical here. But keep trying and eventually he's easy enough.


Now onto Mileena:
She's not very hard to defeat, just jump and block a lot hoping that she burns off her X-Ray meter w/o causing any to little damage. I found that using a combination of both combo 1 and the tactics used on Kintaro help out a lot. Just try to finish the fight w/o getting seriously hurt, I finished w/o losing any health but I also did this w/ a quarter of health and almost won but didn't because of....

Shao Kahn:
To me this guy has always been the master of trolling, a character that is so OP that it just infuriates me because of how cheap of a boss this guy. If you've made it this far w/ a decent amount of health, get ready to finish this guy off.

He has two styles of attack, the first is full contact brawler. Unless you're really good at fighting him , I recommend trying to avoid his physical attack and create as much space as possible. With that space, rhythmically launch the lower fireballs but don't fire too many at once. Shao Kahn has his own counter for this, by throwing a hammer that not only deals massive damage but stuns you as well. So simply avoid getting hit by jumping away from him and if he chases you, dodge his charges and follow w/ combo 1. It's a semi-difficult fight that you can beat if you play cheaply, which is is warranted because of how messed up this mission is.

Final Tip: If you lose the match, you can gain more health by restarting through the Mission Failure menu rather than the pause screen. So there you go and hopefully this helps anyone down the line.

The other guides here do a good job of addressing the major pain points, but there is one that really had me pulling my hair out - Challenge 256 Deadly Alliance. In this challenge you must play as Raiden against Shang Tsung and Quan Chi on hardest difficulty with just one life bar.

The Internet would have you just spam Raiden's lightning projectile. This is effective at range against Shang Tsung, but opening that range can cost you half your life bar. Also, I found this to be ineffective against Quan Chi.

The most effective strategy I found was to use the AI's extreme aggressiveness against it. Wait until it commits to an attack pattern, then teleport (Down, Up) behind and punish with an uppercut or similar high damage move. The block button is going to get a workout in this fight-Quan Chi in particular will require you to be blocking most of the time. Punishing his Sky Drop teleports after blocking are key to winning this fight.

I also found you should not use X-Ray to finish the first opponent to fall. It leaves you wide open for a massive amount of punishment you can't afford. It also is very difficult to land an X-Ray against the AI on this difficulty.

TL;DR:
DO: Spam lightning against Shang Tsung
DO: Block
DO: Use teleport

DON'T: Spam lightning against Quan Chi
DON'T: X-Ray to finish the first opponent

Finally, this guide is not meant to be an all-encompassing Tower map, just challenge 256. Hopefully this helps some intrepid cheevo hunter on this old game! Good luck.
