Munchkin Zombies 3: Hideous Hideouts is a "Dungeon" expansion for Munchkin Zombies. This expansion is similar to Munchkin 6: Demented Dungeons and Munchkin Cthulhu 4: Crazed Caverns.

The package contains:

• 16 regular-sized Portal cards such as "Breach the Perimeter" and "Walking in Circles"
• 20 double-sized Dungeon cards, e.g., "Fort Deadly," "The Creepy Isolated Cabin of the Dead," and "ResurrectiCon," which distort the current rules.
