Cultists of Cthulhu is a game that explores a much darker side to Miskatonic University.  Thomas Elliot provides a very engaging look at Lovecraft’s Mythos allowing players to take the role of different Academics of the university.  Together they must put a stop to an evil presence that is randomized in every game with scenarios and variant rules.  If hordes of horrifying creatures weren’t enough problems one of your group is a cultist that would like nothing more but to see his dark masters tear you limb from limb.
