Cthulhu Deep Green

A roleplaying game about agents of a shadowy government agency tasked with concealing evidence of supernatural threats. Players investigate strange events, protect the public, and decide what their agents sacrifice in the process. The rules support quick setup, improvisational campaign play, and tense, character-focused action for three to six players in two- to four-hour sessions. The book includes guidance for the Handler, inspiration tables, and a complete scenario set in Seattle’s underground dining scene.
