It's the World of Dorkness!
The Munchkins are now vampires . . . and werewolves . . . and changelings. Bash through the haunted house and slay the monsters. The OTHER monsters. You can't slay your fellow munchkins, but you can curse them, send foes at them, and take their stuff. Of course . . .
This is a stand-alone game, which (of course) can be combined with other Munchkin games. And it's illustrated by John Kovalic. OF COURSE. See Igor, Gilly, and all the other Dark Tower characters in their munchkin-vampire finery . . .
So bring along your Coffin (+3!) and wield The Sword Of Beheading People Just Like In That Movie. Face foes like the Banshee, the Heck Hounds, and the dreaded Were-Muskrat. Smite them all, and be the first to Level 10 . . .
