Latest Updates from Our Project:

A look at the slipcase
2 days ago – Wed, Mar 14, 2018 at 10:04:07 PM

We have received a mock-up of the slipcase from the printer, and we are very excited. It features the name of the game on the spine, a green delta on the front, and a familiar pattern embossed into the surface.

With the books, it weighs about 7 lbs, so I expect it to count as Armor 5 in a pinch.

A New Link

Delta Green: The Role-Playing Game is now available on DriveThruRPG as a single download containing both volumes, the Agent's Handbook and the Handler's Guide. We have updated your BackerKit digital downloads accordingly. If your rewards include the "Case Officer's Handbook," which is now the slipcase set, that download link is for the two-volume set. We encourage you to redeem that link to add it to your DriveThruRPG library. And then please add a quick rating to tell others what you think of it.

International Options for A Night at the Opera

When we launched Delta Green: A Night at the Opera as a pre-order on the main Arc Dream web store, its international shipping rates were prohibitively high. That's because that web store is hooked into our main warehouse in the U.S., which delivers international orders via the U.S. Postal Service and charges USPS rates. 

We have implemented an alternative that may be better for those of you outside the U.S. You can now pre-order A Night at the Opera at BackerKit. We have set its non-U.S. shipping rates based on those of the U.K. warehouse which fulfills our international Kickstarter deliveries. That means the shipping rates are more reasonable for most customers outside the U.S.


If you already placed an order at the Arc Dream web store with its higher shipping rates, you can cancel that order and place a new one at BackerKit.

Rewards Status Summary

This Kickstarter project funded so many works that it's easy to lose track of them all. We have launched a new Kickstarter Rewards Report post at to show which rewards have already been delivered and which ones are still in progress. We will update the page from time to time, so check back whenever you get curious about what's still to come. 

Delta Green in Stores

We have a long line of Delta Green products in retail distribution and many more to come. See the March catalog at Tell your friendly local game store to order from their favorite distributor. If the distributor does have it, the store can order straight from our sales agents at Studio 2 Publishing. 

Golden Geeks Reminder

We are up for Golden Geek awards! Voting is restricted to active BoardGameGeek users. If that's you, please vote!

Coming Soon

We and our friends have a lot of new work coming out. Some of it has been in development for a long, long time.

  • The Unspeakable Oath 25 is now in layout. After such a long hiatus, it returns with a deluxe, full-color issue—and a new Patreon program to produce more Cthulhu Mythos RPG materials of the same high quality.
  • This summer, watch for Elder Things, a compilation of Unspeakable Oath issues 22, 23, and 24, with all scenarios and mosters updated to Call of Cthulhu 7th Edition or Delta Green: The Role-Playing Game. 
  • Wrestlenomicon's playtest will wrap up this week and will go to its own Kickstarter project soon. We are editing the videos now.
  • An annotated, deluxe edition of Robert Chambers' The King in Yellow will be available as a pre-order soon. Samuel Araya's spectacularly creepy paintings are all finished, we have preliminary layout treatments, and Kenneth Hite is on hand to write the annotations after his current work on the new edition of Vampire: The Masquerade. This will be a beautiful book.
  • Look for a King in Yellow tarot deck on Kickstarter later this year. Kurt Komoda already finished a full run of card designs in rough black and white, based on the deck imagined by John Tynes and Dan Harms in Delta Green: Countdown. 

Thank you again for backing Delta Green!

The Last Equation
22 days ago – Fri, Feb 23, 2018 at 12:38:25 AM

The Mathematics of Murder
The Mathematics of Murder


We have updated the classic Delta Green scenario The Last Equation for use in Delta Green: The Role-Playing Game. The new edition has been edited and revised, with rules references and stat blocks rewritten for the new Delta Green. It features new, full-color illustrations by the author.

  • If you backed Delta Green: The Role-Playing Game at one of the "All PDFs from this project" tiers, watch for a download link the update #102. 
  • If you already bought The Last Equation at DriveThruRPG or RPGNow, you can download the updated PDF there at no additional charge.
  • And for the first time, The Last Equation is available in paperback. Order the PDF or the paperback here. It will be available in stores this May.

The Last Equation is a poisonous little pill of a scenario. Prepare to have some especially bleak fun with your players.

And the Darkness Spoke, Episode 2

Unfortunately, there is no Episode 2. We played a second session last night, and it was great, but technical glitches ruined the recording. Read a detailed recap here. Watch for the third episode (with no glitches this time, knock on Cthulhu) next week.

Agent Dossiers - And the Darkness Spoke - Slipcases - Proofing
about 1 month ago – Tue, Feb 13, 2018 at 11:42:46 PM

The newest asset for Delta Green games is Agent Dossiers. This PDF package includes pre-written but editable character sheets for every profession described in the Agent's Handbook of Delta Green: The Role-Playing Game. Each sheet includes:

  • Stats as recommended in the rulebook for each profession 
  • Professional skills 
  • A summary of bonus skill options for each profession 
  • A brief description of the profession's core function 
  • All the necessary equipment for characters whose professions require specialized gear, such as special forces operatives and federal agents

Just fill in your Agent's name, the names of your Agent's Bonds, and your Agent's motivations, and you're ready to play. Most importantly, every detail is editable so you can fully customize your Agent.

Agent Dossiers includes two versions: a PDF portfolio, with all the sheets accessible in a single file, that can be used in Adobe Reader and Adobe Acrobat; and a package of distinct, editable PDF files for use on iOs devices. Both versions feature clean designs with no background art, so you can print the sheets with ease, for only $2.99. If you backed Delta Green: The Role-Playing Game at one of the pricey "Everything" tiers, look for a free download link in a separate update.

And the Darkness Spoke

We have launched a new online Delta Green game called “And the Darkness Spoke.” Delta Green co-creator Dennis Detwiller is running it as Handler. Players include Delta Green: The Role-Playing Game co-author Shane Ivey (that’s me), Arc Dream’s Gen Con booth manager John Marron, and John’s wife Amber LeClaire. We are playing the game on, livestreaming it on Twitch, and archiving the episodes on Twitch and YouTube.

You can watch the first episode on Twitch or YouTube. The video quality and audio quality are not great. I’m responsible for that side of things and I’m still learning. They ought to improve in the next episode.

Dennis is posting development notes on Patreon and Drip. The players are staying away from those updates, of course, because they are nothing but spoilers.

The next session is tomorrow night (Wednesday, 13 FEB 2018) at 6:00 P.M. Central time. Tune in or watch when it goes online, and follow along with Dennis’ notes to see a new Delta Green scenario take shape before your eyes.

Ordering Slipcases

A few people have asked about ordering the slipcase for Delta Green: The Role-Playing Game by itself, to go with an Agent’s Handbook and Handler’s Guide that were ordered separately. I am happy to announce that I have arranged with the printer to make that possible. We will set up the slipcase for order on its own later, after we get the books. I don’t want to set that up now, because it would risk confusion having one slipcase product that’s just the case and another that includes the books. Be patient and that will be an option.


We are carefully reviewing physical proofs of the Handler’s Guide and the slipcase. We’ll send a few corrections to the printer this week. After that, the printer will proceed with the main print run.
