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 product contains 25+ maps of the city, its suburbs, and their buildings. Each map has secret information displayed on the GM layer and they can all be repurposed by Keeper's to stand in for other houses in their own Arkham campaigns! Tables for rolling names, Arkham gossip, locations, and even the weather are all included for ease of use in the Arkham Addon. Call of Cthulhu: Arkham also introduces new rules and skills for Arkham investigators.
