Kill the Living! Eat their Brains! Braaiiinns!
It's the sickest; silliest Munchkin yet! You are zombies; kicking down doors and eating brains. The monsters you're attacking are people; some helpless and some hazardous; with a few rogue zombies thrown in. The armor is whatever you've blundered across during your lurching search for brains. So bravely you'll go forth; with mousetraps on your feet and a bowling trophy protecting your poor rotting head . . . to level up; or to die.

Again.
