Call of Cthulhu

Classic horror RPG inspired by the writings of HP Lovecraft and others who contributed works to his Cthulhu Mythos Cycle. CoC was original designed for encounters with Mythos entities in the period in which Lovecraft was writing (the 1920s), but has been supplemented with worldbooks for the 'Gaslight Period' (1890s) and for an imaginative fusion of the Mythos with UFO conspiracy horror in a contemporary setting (see Delta Green).

Originally published by Chaosium and now supported by Pagan Publishing, Call of Cthulhu uses Basic Role Playing mechanics.
