Mortal Kombat Arcade Kollection

This achievement was so easy to do once I found a little trick. It doesn't work every time. I have tried it 6 times and it worked for 5 of them.

Start up MK2 on very easy with the character Baraka. Now be holding DOWN so that when the match starts you are crouching. Your opponent should walk up to you and all you need to do now is tap A to punch them when the get close enough. Do this for 2 rounds and you should get 2 flawless victories.

The only time this didn't work for me was when my opponent jumped towards me and kicked as their first attack. That happened once out of 6 attempts.

This is a really easy achievement. First of all set the difficulty to Very Easy. Now start up MK1 and pick any character you want.
Go all the way to the corner and keep jumping, when the opponent approaches, press B. Here's a video I recorded.

These are both very informative and i would like to add, you do not have to get them in a row. I won my first round flawless. Lost the second round and finished the third round flawless and still got the achievement.
Hope that helps a little.

I did this in MK1 with Raiden. My first fight was against Sonya and i spammed Raidens Torpedo move (Away, Away, Towards) after the move Raiden jumps backwards whether the move is blocked or not while in the air you can push the Away, Away part of the move so you can hit towards as you land and head straight towards the opponent again. If you find yourself in a corner jump over the opponent, jump backwards a second time avoiding their attacks and repeat the process. It took me a couple of tries but i got it on the third go.

I did this on MK1. First thing you should do is turn the difficulty to very easy. Then select MK1 and pick any character to start. Lose the first match really quick and continue. Doing this will make the CPU weaker in the next fight. Choose Raiden and spam his torpedo(Back,Back,Forward). The CPU will let u hit them the first two times usually and then block the rest of the match. Remember to keep tapping back while you fly at your opponent and bounce back and as soon as you land all you have to do is tap forward to torpedo at him again. Keep repeating this. Even though they block it still takes a little bit of life from them. The reason why u lose the 1st match is because the CPU weakens and will not counter attack with a projectile after they block your torpedo. Eventually you will get cornered because your opponent will keep walking toward you after blocking the torpedo. When this happens simply jump over your opponent and jump a 2nd time in the same direction to get distance from your opponent, then repeat the process. I did this on an Endurance Match so it should be no problem to do it against one opponent at the beginning of the ladder. If you get hit then just lose the match and continue again. Each time you continue the CPU will gradually get easier as well

I did this in umk 3. beat the arcade or do the 8 player tournament with subzero. you will be given a choice of something to pick. pick the 4th option which is a 3. as sub zero just spam his low punch as you will be fighting noob saibot. he will be stuck in a glitch and you can easily get your flawless victories. if he happens to hit you just let him win that round then try again the next round.

This is likely easiest on the first Mortal Kombat, as enemies are easier to trick. You can set the difficulty to Very Easy to make this a little easier on yourself. Try for the achievement on your first few opponents, as they are the easiest.
I found the simplest way to do this is to spam the sweep, which is done by pressing away from the opponent and B at the same time. It doesn't matter which character you use, as everyone has the same basic moves.

Boot MK1 on very easy so the first opponent is not too aggressive and then, there's a little trick that works really fine in this episode : jump back at the start of the round until you're at jump distance and then, jump forth and kick. Jump back again while your opponent gets up and jump forth and kick when you're about to touch the ground.

The CPU rarely blocks that kind of attack if its your first fight on the ladder and you just need 6 kicks to defeat him.

Eventually, if he happens to fight back and hits you, you can still lose the round and win the next as you will get a double flawless victory even if you lose a round.
