Welcome to America at the end of the millennium. Do you know who is pulling the strings?

Delta Green knows. Things from beyond space and time that lurk and titter in the shadows, the slow rot at the core of humanity, the dark stars that whirl madly above - these are the true masters of the world. Delta Green has been fighting since the 1928 Raid on Innsmouth, and the fight still rages on.

This book is your weapon and your guide.

The largest Call of Cthulhu sourcebook ever.

Inside you'll find a secret history of the 20th century and the movers and shakers who are players in the game: Delta Green, the outlaw conspiracy working inside the U.S. government to fight the darkness; Majestic-12, the clandestine agency that cuts deals with aliens and reports to no one; SaucerWatch, a UFO study group closer to the truth than they know; the Harotechnia, immortal Nazis who serve a risen Hitler; and the Fate, an occult syndicate that knows where the bodies are buried.

• new skills
• new spells
• new weapons
• new Mythos tomes
• profiles of thirty-six real-world intelligence and law-enforcement agencies, with character templates for each
• a look at Mi-Go biology, philosophy, and operations
• analysis of the Cthulhu Mythos in the modern day
• a factual history of the U.S. intelligence and law-enforcement community
• dozens of useful NPCs, campaign-construction guidelines
• two scenarios
• a short campaign
• and more

The book that started it all! Five years in the making, DELTA GREEN won the Origins Award for Best Roleplaying Game Supplement of 1997 and has received unanimous critical praise.

Delta Green tells the story of the Cthulhu Mythos in the modern age. Conspiracies abound, and this is one of the deadliest: Delta Green is a handful of men and women who use the resources of the government to fight a secret, illegal--some would say treasonous--war against monstrosities which threaten their world.

This is a massive 1990s sourcebook dealing with government conspiracies, alien activity, undead Nazis, and much more.

Note: Delta Green has been out-of-print for some time and this is a scanned image product.

Is there any way I could get the 2007 version? it was dual-statted for the D20 system. I can't find a pdf of that version anywhere.

Which version of Call of Cthulhu does this mesh with?

It was designed for the 5th edition, although there is a version that includes d20 statistics; this would appear to be the former.

It's also usable with 7e with a tiny bit of work, not much. It's completely usable with modern DG as well.

Coming back to this: If you play to use it with 7e, make sure you read the full auto rules for 6e or 5e as they are very different from 7e.

How's the quality of the printed book? I ask because I would love to get this but it has a warning about it being from a scan and I know how rough those can be. Anyone gotten one yet?

I just got mine in the mail yesterday and I am pretty pleased with it. It is not perfectly crisp (most noticeably in areas where the text originally had highlighting) but still very readable. Certainly better than paying twice as much for the original printed book online.

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.
