From the itch.io page: Building upon the groundwork set out in Cthulhu Dark by Graham Walmsley, Cthulhu Deep Green contains a modified rules set for playing as Agents of The Conspiracy: a shadowy government agency tasked with concealing evidence of the supernatural. This 52 page PDF contains all the basic rules you’ll need to play, Handler’s advice for running your own scenarios, and tables to help inspire play. Playable with three to six players with sessions lasting two to four hours. Also included: Food of the Gods, a fully realized scenario set in the Seattle underground dining scene. With a focus on quick setup and improvisational campaign play, the rules of Cthulhu Deep Green are designed to focus the human element while keeping the action tense and dramatic. What will your agent give up to protect the public from terrors beyond sense or reason? Pick up your phone and report in.
