Hammerfight.

“In the physics-based gameplay, the player swings large melee weapons and relies on centripetal force to give the object enough kinetic energy to destroy enemies. The demo release had six main types of weapons - four melee and two ranged.

The different weapon types offer a certain variety. To be a slow, but well-armored powerhouse using hammers or maces to deliver slow, but crushing blows, or a nimble, but poorly protected sword-wielder, delivering quick, but weak attacks, is entirely up to the player. The game also contains a few different play modes, such as a hunt on worms or a Hammerball game.”
