The Delta Green RPG was launched in 2016 by Arc Dream Publishing following a Kickstarter campaign and building on their experience of writing Delta Green material for Call of Cthulhu. Delta Green brings the Cthulhu Mythos, and the men and women who encounter it, squarely into the modern day.

In Delta Green, the cosmic horror of the Cthulhu Mythos meets modern-day technothriller conspiracy. Delta Green postulates a secret group of men and women dedicated to investigating and neutralizing inhuman and supernatural horrors, misappropriating the resources of the U.S. government to wage a war that they must at all costs keep hidden.

Originally a unit of the Office of Strategic Services (the forerunner of the Central Intelligence Agency), Delta Green continued as a project of the National Security Council after the OSS shut down. Delta Green was officially disbanded and its activities made patently illegal after a disastrous operation in 1969. But its members carried on. For three decades they acted without the cover of authority, a criminal conspiracy to confront the horrors that threaten mankind.

During the Global War on Terror, Delta Green was reactivated as an unacknowledged special access program (TOP SECRET/SAR-DELTA GREEN) within the Department of Defense. A handful of control officers are authorized to form task forces of agents with DELTA GREEN clearance, drawn from across the executive branch: FBI agents, special forces operators, CIA officers, civilian contractors, and more.

Only individuals with DELTA GREEN clearance are allowed to know what Delta Green operations do. Of course, some officials who lack that clearance still expect hints — especially when their agents vanish on Delta Green operations and never return. They are allowed by winks and nods to understand that it's a high-level counterterrorism program. It is not. Delta Green agents fight, conceal, and collect intelligence on things that man was not meant to know.

Since the program was reactivated, Delta Green agents have access to more official resources and contacts than ever. But they are subject to greater risks of scrutiny - and therefore the risk (some say the certainty) of their discoveries and operations being put to, let's say, unanticipated use. As the old saying goes, be careful what you wish for.

Recognizing that risk, many agents and operatives from the old days refused to come in from the cold. Those outsiders continue their crusade in secrecy, without oversight and without sanction, willing to break every law and moral code to fight horrors that nobody can comprehend.
