The game plays somewhat like a fighter. First, you will notice that players have a life bar. To win the fight you must KO your opponent 3 times, or finish them off quickly with a FaceBreaker Move. Each character has his or her unique fighting style and set of moves. That is not to say you will have to spend your time learning how to execute each move, because the controls are the same for each fighter.
You will however, have to learn when to use individual character moves, since each has their own way of using their abilities. You get the Spanish pretty boy, the tough chick who could have doubled for Linda Hamilton in Terminator 2, the clumsy but lovable kung-fu junkie who is one part Chris Farley one part Jack Black, the stereotypical Russian tough-guy/madman and bunch more.
