Demented Dungeons introduces a new twist on Munchkin - Dungeons!
Now you can enter the Dungeon of Elvish Excess, where everyone is an Elf. Or take a Portal to the Dungeon of Manga Wrangling, where tentacles are even more dangerous. Or power up in the Dungeon of Unexpected Epicness although it's hardly "unexpected," given the name. Or all of them at once!
Each of the 20 double-sized Dungeon cards adds a new rule that affects the entire party, and maybe the monsters too!
Use the 16 Portal cards to jump from one Dungeon to the next in your search for gold and glory - and may the best munchkin win (for a certain definition of 'best' which may include most evil, conniving, backstabbing and down right treacherous).
Not a complete game the original Munchkin is needed to enjoy this expansion.
