Toribash(Warning: Is awesome)

[supersonic45]

Toribash, is, the best fighting game. And 100% free. In this game, you use your knowledge of the human body and physics to create your own moves. Decapitating is awesome in this game.

There are so many mods, like swords, zipline racing and all, you won't be left bored too long, even while waiting for player's turns.

Sounds like a sequel to Mugen...

Ah, this one's great. Too bad I fail horribly at it. But even if you're too stupid to fight for real, it's fun to mess around with the millions of mods.

This looks unbelivably awesome, I'll give it a download and try it out
