There's a demo and it is certainly... different. Manned helicopter-like flying machines, 2D physics based combat with flails / hammers / maces that you 'spin' your mouse in a circle to whack the crap out of your opponent with them.

on the store page:"The moment you start up the game, you will be kicked in the balls" - Anthony Burch, Destructoid
