Kill the Living! Eat their Brains! Braaiinns!
It's the sickest, silliest Munchkin yet! The players are zombies, kicking down doors and eating brains. The "monsters" they're attacking are people, some helples and some hazardous, with a few rogue zombies thrown in. The armor is whatever they've blundered across during their lurching search for brains. So bravely the munchkins go forth, with mousetraps on their feet and a bowling trophy protecting their poor rotting heads...to level up, or to die. Again.
