Release [Chaosium] Out now for Call of Cthulhu - our long awaited and eagerly anticipated Arkham book

Michael O'Brien




Call of Cthulhu: Arkham is the definitive guide to the signature setting of Call of Cthulhu.

On the streets of Arkham, the threat of the Cthulhu Mythos is ever-present. A quiet town in New England—home to the prestigious Miskatonic University—Arkham’s underbelly hides criminals, speakeasies, and a witch-cursed history.

A Sandbox Setting

With 290 locations detailed across 9 neighborhoods, Call of Cthulhu: Arkham is the perfect supplement for a sandbox-style campaign. The compendium also contains Gossip & Rumors to use as scenario seeds, and over 80 fully-detailed NPCs with their own secrets to discover—investigators will never be without a lead to follow up on!

New Rules & Game Aids

The book contains two Arkham city map posters (one designed for players, and one marked with hidden information for the Keeper!), as well as a poster-sized copy of the front page of the Arkham Advertiser—the perfect prop for any game set in Arkham. Call of Cthulhu: Arkham also introduces new rules and skills for Arkham investigators.
