Smash Up: The Obligatory Cthulhu Expansion
The Obligatory Cthulhu Set features crazy Cthulhu cultists, fishy Innsmouth locals, horrifying Elder Things, and good-old Miskatonic University members (the Fightin` Cephalopods) thrust into the chaos of Smash Up! This set also introduces a new card type (`Madness`), that each of these groups use to various effects. But, remember... Madness brings you power - for a price!
