The Great Old Ones ruled the earth aeons before the rise of humankind. Originally they came from the gulfs of space and were cast down by even greater beings. Remains of their cyclopean cities and forbidden knowledge can still be found on remote islands in the Pacific, buried amid the shifting sands of vast deserts, and in the frigid recesses of the polar extremes. Now they sleep -- some deep within the enveloping earth and others beneath the eternal sea, in the drowned city of R'lyeh, preserved in the waters by the spells of mighty Cthulhu. When the stars are right they will rise, and once again walk this Earth.

Call of Cthulhu is Chaosium’s classic roleplaying game of Lovecraftian horror in which ordinary people are confronted by the terrifying and alien forces of the Cthulhu Mythos. Call of Cthulhu uses Chaosium’s Basic Roleplaying System, easy to learn and quick to play.
