Face the Unknowable. Track the Unthinkable.

Face the unknowable. Build investigators, track their slow spiral into madness, and document every sanity-shattering encounter. In the mythos, knowledge comes at a price.

What is Call of Cthulhu 7th Edition?

Call of Cthulhu 7th Edition is a horror investigation roleplaying game based on H.P. Lovecraft's Cthulhu Mythos. Players take on the roles of Investigators—ordinary people who uncover cosmic horrors beyond human comprehension. As you investigate mysteries, your character's Sanity slowly erodes, skills improve through use, and the line between reality and madness blurs.
