Enter the awsome universe of the Cthulhu Mythos, those dread tales in which magic, science, arcane lore, and dark destinies irrevocably sear the lives of those for whom the bizarre and the curious have unseemly attraction.

Specially designed to portray the situations and denizens or the Mythos, CALL OF CTHULHU uses a variant of the Basic Role-Playing system, adding characteristics for Sanity and Education.

The first book included is Call of Cthulhu, which explains the characteristics, skills, occupations and resources available to the Investigators, the many beings specific to the Mythos (deep ones, flying polyps, dimensional shamblers, shantaks, chthonians, Cthulhu, Yog-Sothoth, Nyarlathotep, etc.) full rules for magic and the use of the famous books (the Necronomicon, De Vermiis Mysteriis, Unausprechlichen Kulten, etc.) which have fascinated readers for decades. This book translates the Mythos fiction into role-playing termas. Scenarios are drawn in the style of Lovecraft, not directly from specific books.

A second book is a A Sourcebook For The 1920's, consisting of non-Mythos data - price lists, plans, maps, distances, thumbnail biographies, as a garden-variety monsters upon which budding Investigators can sharpen their skills. This box also contains character and monster silhouettes for play, Investigator sheets and a world map of ‘dig’ sites.
