Smash Up: The Obligatory Cthulhu Set features crazy Cthulhu cultists, fishy Innsmouth locals, horrifying Elder Things, and good old Miskatonic University members (the Fightin' Cephalopods). To be certain we got it right, this set also includes a new card type fittingly known as "Madness" that each of these groups can use to various effects. Just remember that Madness brings you power but at a price (joking!).
