It is the 1960s. The stars are coming right.

The United States declares war on poverty and sends half a million troops to Indochina; desegregates voting booths and shoots rockets at the moon. Everyone believes that if we put our mind to it and our backs into it, there’s nothing we can’t do to make the world better, for America and everyone else.

You know that this is a lie. You are an Agent of DELTA GREEN, an authorized but unacknowledged black program of the United States national security establishment, tasked to hunt and destroy the Cthulhu Mythos. You know that plans and ideals, peace and love, matter less than a single atom drifting in the galaxy. All you can do is rage against doom, burn out your mind and body, and damn your nonexistent soul keeping your family, your country, your planet, ignorant and safe for one more day.

Written by ENnie Award-winning designer Kenneth Hite, The Fall of DELTA GREEN corebook adapts DELTA GREEN: THE ROLE-PLAYING GAME from Arc Dream Publishing to the award-winning GUMSHOE system. It opens the files on a lost decade of anti-Mythos operations both foreign and domestic, the last days of DELTA GREEN before the Joint Chiefs shut the program down in 1970.

Players take on the role of DELTA GREEN operatives, assets, and friendlies, in deadly one-shot adventures or a campaign spanning the years from hope to madness. Hunt Deep Ones beneath the Atlantic, shut down dangerous artists in San Francisco, and delve into the heart of Vietnam’s darkness.

The Fall of DELTA GREEN features:

  • Lethal combat and covert action in the 1960s, featuring assault rifles, flamethrowers, mortar shells, spy cameras, truth drugs, and getting rid of the bodies DELTA GREEN operations always seem to leave behind.
  • “Back in the World” vignettes that let you explore the human side of your Agent’s life—and often track their slow destruction by DELTA GREEN.
  • The rich world of the Delta Green Mythos, including a gazetteer of unnatural lands, the desperate truth of Hastur, and period takes on the top-secret MAJESTIC program, the Nazi Karotechia, the alien Greys, and the decadent Cult of Transcendence.
  • Detailed advice for making mysteries, magics, monsters, and DELTA GREEN operations.
  • Interoperability with Night’s Black AgentsTrail of Cthulhu, and The Esoterrorists: Use your favorite GUMSHOE rules to battle the unnatural in the 1960s!

The decade begins in sunny optimism, and ends in nighted disaster in the jungles of Indochina.

After the summer of the 1950s, now comes the fall—The Fall of DELTA GREEN.

The Borellus Connection hasn't been released yet. The PDF will be released one to three months after the print book has been published.

Given the print edition is out of stock, I'd love a PoD option here.

Any very rough ETA for the reprint? I am hunting this game everywhere but there are only 300+ USD eBay offers.

The reprint is currently underway. The books should hopefully be with us within the next couple of months.

This is spectacularly good - I picked up a print copy from The Dragon's Trove and could not put it down. I also preordered the upcoming campaign The Borellus Connection from Pelgrane - includes a draft pdf of the book. It may be the best campaign I have ever read, for any system - Charles Dexter Ward meets The French Connection meets Apocalypse now.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
