The game is a GM-less black comedy lampooning academia, and designed for single-session play at the end of which a winner is determined. It is set among the internal politics of a buttoned-down New England college campus in 1919, with the titular roach being a soul-eating telepathic insect bent on destroying human civilization. Characters under the control of the roach succeed at tasks more easily, but can not win if they are still under the control of the roach at the game's end.
