Call of Cthulhu

The question is not whether you’ll go mad, but how!

Call of Cthulhu was first released in 1981 and has been going strong since. Investigators search for hidden knowledge, and when they find it, they encounter far more than they imagined possible. The powerful secrets they uncover will slowly drive them mad, if not kill them first. This is a game where caution and wits get you further than large-caliber weapons.


Here’s how publisher Chaosium describes Call of Cthulhu:

Playing the role of steadfast investigators, you travel to strange and dangerous places, uncover foul plots, and stand against the terrors of the Cthulhu Mythos. You encounter sanity-blasting entities, monsters, and insane cultists. Within strange and forgotten tomes of lore you discover revelations that man was not meant to know. You and your companions may very well decide the fate of the world.

Core Rules Reviews

  • “Combat is still incredibly dangerous, sessions can be played with a minimum of dice rolling, and intelligent play still works better than going in guns blazing. I’d have to say it’s still my favorite RPG.”Daniel Stack, 19th Level
  • “If you enjoy tension and suspense, in beating the odds rather than just dialling in a victory, or you just enjoy cerebral games where you’re going to be relying on your wits to pull you through more often than a dice roll, then Call of Cthulhu might just be for you.”Jay Draper, The Mad Adventurers Society
