This subject is written on a topic in the real world and reflects factual information. This subject contains information from the Expanded Cthulhu Mythos, and not based on H.P. Lovecraft's works directly. Delta Green is a stand-alone Cthulhu Mythos roleplaying game published by Arc Dream Publishing.


Updating the original Call of Cthulhu supplement Delta Green from the 1990s into a post-911 environment, Delta Green continues with the theme of a covert United States government agency devoted to combatting supernatural threats. It also advances the story of the fictional group.

Gameplay involves the players taking on the role of Delta Green agents who are assigned to investigate and, if necessary, contain or destroy any threat to humankind by any means necessary. This includes the influences of the Cthulhu Mythos, and also more traditional supernatural forces. The game uses a modified version of Chaosium's Basic Role-Playing (BRP) system, allowing it to be used in conjunction with many Call of Cthulhu supplements with little to no adaptation.
