Call of Cthulhu: Delta Green
“Welcome to America at the end of the Millennium. Do you know who is pulling the strings? Delta Green does. This outlaw conspiracy operates within the U.S. government, fighting a clandestine, unauthorized, and highly dangerous rear-guard action against the forces of darkness. This exhaustive sourcebook describes the decades-long history of Delta Green as well as its allies and adversaries. It includes extensive source material on a wide range of topics, including factual profiles of more than thirty U.S. military/intelligence agencies with investigator occupation templates for each. Also included are two scenarios and a mini-campaign, plus guidelines on setting up a long-term Delta Green campaign. This is the longest CoC supplement ever published, and it’s jam-packed with information.”
