"Cthulhu Abides: A Roleplaying Game of Investigation & Madness" is a tabletop roleplaying game (RPG) set in the imaginative worlds of H P Lovecraft's gothic horror. The rules use a 'poker dice' mechanic and focus on a guided character generation system for Edwardian characters in a British setting, a novel approach to Dynamic Madness and a freeform magic system. A Clue Point mechanic systematises investigative roleplay. The rules include full specifications for period weapons, Lovecraftian Grimoires, monsters and a new interpretation of the Dreamlands setting. This latest edition includes interior art.
