"Munchkin Cthulhu is a standalone game in the Munchkin universe, this time lampooning Lovecraft's Mythos
and the horror gaming that surrounds it. This base game features four
new Classes, including the Cultist, and a lot of classic monsters from
outside reality – and they all have Stuff you can take from their
twitching bodies. You can play Munchkin Cthulhu by itself, or combine it with any number of other Munchkin titles for mind-bending silliness."
