Call of Cthulhu is a horror-fiction role-playing game of secrets and mysteries based on the worlds of H. P. Lovecraft. Playing the role of investigators, players travel to strange and dangerous places, uncover foul plots, and stand against the terrors of the Cthulhu Mythos… potentially deciding the fate of the world! Encounter sanity-blasting entities, monsters, and insane cultists, and discover revelations that man was not meant to know within strange and forgotten tomes of lore.
