muahaha, 9MB of free game to download, and multiplayer available, design your moves, can move all parts of the body to make an attack, and attack your opponent, check who has the best moves!

This is a video of some guys who plays this game, some great "kills" muaha.

I've tried it...
I like it but its a bit hard to remember moves and stuff like that...
Anyway i suggest you to try it
