The Last Equation
over 3 years 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
over 3 years 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.
