The worshippers of a monstrous entity hold unspeakable ceremonies to invoke their idol and enslave humanity. To foil their plan, Professor Armitage enlists the help of an adventurer to infiltrate the cultists and steal their cursed books.
Call Me Cthulhu is a hidden role team game based on the mechanics of the famous Nosferatu.
This time, the good guys become the bad guys, and vice versa!
Call Me Cthulhu brings the same sensations as Nosferatu, but reveals an additional strategic dimension. The games often lead the cultists to make a fundamental choice, much more marked than in Nosferatu: try to eliminate the infiltrator, at the risk of making a mistake, or count on the possibility of bringing his mental health to zero by summoning the most powerful creatures?
