Delta Green: The Role-Playing Game

Delta Green: The Role-Playing Game


ENnie Award Winner for 2018: Best Game (silver), Best Production Values (gold), Best Rules (gold), and Product of the Year (silver)!

Born of the U.S. government’s 1928 raid on the degenerate coastal town of Innsmouth, Massachusetts, the covert agency known as Delta Green opposes the forces of darkness with honor but without glory. Delta Green agents fight to save humanity from unnatural horrors—often at a shattering personal cost.

In Delta Green: The Role-Playing Game, the players are those agents. They fight to save human lives and sanity from threats beyond space and time. Delta Green’s percentile-based rules are compatible with 20 years’ worth of Delta Green scenarios and sourcebooks.

Delta Green includes two full-color rulebooks:

The Ennie Award-winning AGENT'S HANDBOOK features rules for creating agents and playing the game.  It includes:

  • Rules for creating agents, with dozens of professions from throughout the U.S. government and the civilian world. 
  • Rules for tense, fluid investigations; players who use their agents' skills in clever ways have the best chance to succeed—and survive. 
  • Nerve-wracking rules for combat, where random disasters can undo the most careful planning and the human psyche is as vulnerable as the body. 
  • Mind-melting Sanity rules, which see agents gradually and inevitably deteriorate from too much exposure to trauma—and sometimes snap in an instant from overwhelming terror. 
  • Rules for “home” scenes where players can see what their agents are fighting for. 
  • Intuitive rules for equipment and assets, which let you determine on the fly whether something is available without having to plan it out ahead of time. 
  • Dossiers of the federal agencies most likely to be featured in Delta Green games, focusing on the details players want to know when they play their agents. 

The HANDLER'S GUIDE is written for the game moderator who presents the mysteries and horrors of the Cthulhu Mythos. It includes:

  • A history of the world of Delta Green from prehuman history to the present day, with campaign tips and scenario seeds on every page. 
  • Horrifying rituals, unnatural entities, and reality-shattering Great Old Ones. 
  • Rules for creating new threats to shock and terrify your agents. 
  • The secretive Delta Green organization in deep and disturbing detail—and the other ruthless conspiracy that claims it is the real Delta Green. 
  • Guidelines for creating original scenarios and campaigns using the resources in this book. 
  • “Operation FULMINATE: The Sentinels of Twilight,” a sample scenario, ready to play.

Delta Green: The Role-Playing Game is supported by 20 years of scenarios and sourcebooks, with more to come.

A universe of cosmic terror lurks, just out of sight. Can your agents stand against it?

Will the price for the physical book go down? It'd cost 300NZD for me to play this here.

Why are there two versions of the Agents Handbook for download:


Which one is newer?
Please delete the old one to avoid confusion.

Thx in advance.

It's cheaper to buy these books separately...

Does the game need the core book of CoC ?
Customer avatar

No it does not. Arc Dream's Delta Green is a standalone game.

No, this is a self-contained game

It appears that the Agent's Handbook in this set (dated 2016-04-27) is missing the PDF bookmarks; the stand-alone Agent's Handbook (dated 2016-04-26) is not.

So how does this fare when compared with world of darkness? Like based on description alone it sounds a lot like a task force Valkyrie game of hunter the vigil

Actually I would compare this more to Conspiracy X.

Will the boxed set ship to game stores at the same time the Handler's Guide ships in June?

What's the difference between this product and these ones : & ?

That appears to be the previous edition. This is the newest released edition, that is the 2016 set that is also based on a previous edition of the BRP rules I believe.

There isn't a "previous edition". It's a complete set of both the Handler's and Agent's books - which was originally mooted to be a single book, incorporating the previously released Agent's (aka Player's) Handbook, but eventually got reverted to two books due to the overall page count being huge. There is no real difference with those previous PDFs, although this will end up being the final physical product (in a slipcase), I presume with any errata fixed, etc.

There is no slipcase it is a pdf. The separate pdfs come to a total of £31.29 so what is the point of this?
Customer avatar

I guess they have revised pricing as at the current prices it the same price as purchasing the two pdf's

I think this release is mainly for the benefit of getting it out to the kickstarter backers - who are discounted anyway.
Customer avatar

Having both books in a single product is mainly for convenience. If you already have the PDFs of the individual books, you're set.

Original electronic
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.
