For those of you that are new to the game (mk arcade kollection) i am gonna post some tips and advice on how to defeat all your opponents, because i have read a lot of people saying that they are having trouble because the cpu player is totally cheap and broken, hope it helps: first and most important, NEVER try to uppercut the cpu player because it will just uppercut you back, also never attempt throwing, that does not work, not even with sub zero's freeze move, you can get a free hit doing the following...when the match starts duck, the opponent will walk straight at you, all you have to do is jump back when it's almost next to you, the opponent will jump at you without kick or jump and this right here is the moment you get a free hit, you gotta practice it a lot, usually it won't happen if it's on easy, you gotta have the game at least on medium for this to work, and it works only if you are player 1 and it works with 7 characters, 1)johnny cage 2) reptile 3) subzero 4) shang tsung 5) jax 6) baraka and 7) scorpion, this will not work with liu kang, kung lao, raiden or the ladies...2nd tip is if you play as player 2 there is also a trick for a free hit: when you're playing, jump to your opponent WITHOUT throwing punch or kick, you will notice your opponent walk back away from you, follow him/her without attacking it until both of you are in the corner, the cpu player will keep walking away permanently unless you attack him, just wal away from it, when it stops walking it will wait a few seconds and throw a proyectile, when it stops, just walk at it, and after it throws the proyectile,you get a free hit. hope his information will help players with trouble.
