I tried Kung Fu Chaos and it was very interesting. Ive never played a game so crazy like this. You can do all sorts of crazy stuff in this game. Like smash a chair over an enemy, take Ninja swords and chop up a guy, throw a guy into the water and make him drown, take a person from the crowd and throw him at your enemy and more... Anyways, The gameplay is pretty good, it takes about 30 Minutes to get used to it because Xbox has a lot of buttons. The graphic are good but Xbox quality. The sound is good because you can hear your enemy say "Ow" and hear the chair breaking over a guys head. The Length of the game is not so good because you can only have 8 characters and like 14 levels (I think).
In Conclusion, This game is excellent. If your still not sure of buying this game, Rent it and you wont regret it... Trust Me ;-)
