This cooperative board game blends the mechanics of Pandemic with the cosmic horror themes of H.P. Lovecraft. Players take on the roles of investigators working together to seal interdimensional gates and prevent the rise of Cthulhu. The game includes custom plastic miniatures representing investigators, cultists, and shoggoths. Players must manage their sanity while gathering clues and facing supernatural threats. Twelve distinct Old Ones appear in the game, each with unique abilities that require strategic adaptation. The core gameplay retains Pandemic's cooperative structure while introducing new horror-themed challenges and mechanics.
