Munchkin Axe Cop

"Munchkin Axe Cop is a simple, lightweight multiplayer "take that" style card game. Cards represent character abilities, items, monsters to fight, and cards to make monsters harder to defeat (for monsters other players are fighting) or easier to defeat (for you). Every time you defeat a monster, you go up a level. The first player to level 10 wins."
