You liked the double-sized "Dungeon" cards for classic Munchkin. So here they are for Munchkin Zombies!
In Hideous Hideouts, these cards are places where the zombies can find more yummy braaaaaains! Fort Deadly, the Creepy Isolated Cabin of the Dead, Resurrecticon . . . you get the idea. And cards like Breach the Perimeter and Walking in Circles will keep the band of hungry undead on the move as they hunt for tasty, tasty survivors.
This is an expansion for Munchkin Zombies. It is not a stand-alone game.
