If smacking someone in the face with a machinegun of some sort doesn't do it for you in games, then this is the game for you! It's not a game where you click and the game plays a hit animation for whatever you clicked. In this game, your character basically becomes a physics object and the force will actually transfer to your opponent ( e.g. if you roundhouse someone, they will go FLYING in the opposite direction (unless they blocked, in which case, awww too bad)).
Oh, there's also parkour.
And a forum.
and a community-created mod browser.
Ok go buy it now.
P.S. It isn't a furry game, nor is Lugaru. Apparently, David thought it would be too brutal on humans and with rabbits, the jumps and what not are more realistic. And the combat is pretty brutal.
Oh, and there's instakilling wolves. And weapons.
Ok seriously now go buy this game.
