Delta Green: Handler's Guide
almost 5 years ago – Tue, Oct 31, 2017 at 05:35:19 PM

The Handler's Guide has stolen our brains.
The Handler's Guide has stolen our brains.


This is Shane Ivey from Arc Dream Publishing. As I write, BackerKit is distributing download links for the Handler's Guide. If you requested the "Case Officer's Handbook" option in your rewards, you should find a link in your BackerKit digital downloads. 

That link is a backers-only coupon to download the Handler's Guide from DriveThruRPG at no cost. You're all on the honor system, here! Since it's meant for backers only, the coupon expires in two weeks. Please redeem it now and PLEASE keep it to yourself. 

If the coupon expires before you get around to it...or if you have any trouble redeeming it...or if your rewards included the "Case Officer's Handbook" option and your digital downloads do not include the Handler's Guide, don't worry. Just message or email me with your backer details and I'll sort things out.

Anyone who did NOT request the "Case Officer's Handbook" in BackerKit can buy the Handler's Guide in PDF at DriveThruRPG or at And it can still be preordered in hardback (with the PDF as a free download) at BackerKit.

All of this can be yours.
All of this can be yours.


What's Next

The Handler's Guide goes to the printer soon. That means it will start shipping in hardback in the spring. In the meantime, we encourage diligent readers to keep track of any errors you find in the book. I'll send instructions soon for you to send those to us. That will help us make it as perfect as possible before it goes to press.

We're moving on now to the next Delta Green books: Deep State, Impossible Landscapes, PISCES, Operational History, and Falling Towers. We'll continue putting out new scenarios every month. (You've seen all the scenarios, right?) We'll keep sending previews, early drafts, bonus downloads, and podcasts to the Delta Green Patreon. And there's the long-delayed next issue of The Unspeakable Oath. And Wrestlenomicon. And the annotated King in Yellow. And a few personal projects that have been waiting for this monster to get out of our heads. And...well, you'll see.

In the meantime, please enjoy the Handler's Guide

And please leave a rating or review at DriveThruRPG. Other readers need to know what you think of Delta Green and the Handler's Guide.

The Fall of Delta Green: plain text for backers
almost 5 years ago – Mon, Oct 09, 2017 at 08:22:28 PM

“To a season of political and social upheaval was added a strange and brooding apprehension of hideous physical danger; a danger widespread and all-embracing, such a danger as may be imagined only in the most terrible phantasms of the night." -- H.P. Lovecraft, "Nyarlathoptep"

A quagmire overseas chews up American forces. 

Apocalyptic cults rise in the Middle East, riots paralyze Paris, and Russia moves aggressively into Europe. 

The United States wages secret war around the globe while its social fabric shreds and its cities crackle with gunfire. 

New technologies, new sciences, and new music revolutionize our lives. 

The Earth’s ecology teeters at the brink of toxic ruin. 

The stars are coming right. 

It is 1968.

The Slipcase Option: Notes from Gen Con
almost 5 years ago – Thu, Aug 24, 2017 at 12:25:25 AM

Dennis Detwiller reports on Gen Con 2017:

Gen Con 2017 was special in many ways. It was the 50th anniversary of the show, for one. For another, it was totally sold out for the first time.

They had a huge museum of roleplaying-related artifacts from the before-time, and guess what? You can be proud: Delta Green was in it (along with many other products I had a hand in, like The Unspeakable Oath, Primal Order, and Magic: The Gathering). Neat to be a fossil that's somehow still clawing away at the ecosystem (go, team coelacanth!).

We ran into the usual suspects. Shane Ivey, my stalwart creative partner, was there managing all things with a computer-like precision (that the computer was a first-generation Amiga color, you'll have to excuse). Simeon Cogswell, our layout guru, continued a long tradition of complaining while working too hard for too little money. Booth manager John Marron was happy at all times (despite our best efforts), perhaps because he inflicted the Bob Ross board game on us and managed to get me to play. Finally, Scott Glancy created a new look at the booth called “enturly,” appearing entertained and surly at the same time. Ross Payton and the RPPR guys were there, too (minus Caleb—boo!), and we tortured then endlessly. (Pro tip: Call Ross “Caleb,” he loves it.)

We even got in a bit of a Delta Green game. We played "Operation SUGARTOWN" with Ross, the Arc Dream team, and a few RRPR regulars. Though we didn't get to finish it, much fun was had. Look for the operation in a writeup on the Patreon next month.

At the booth, we had a bunch of Delta Green newly appearing in print (full color!), and they are gorgeous: Kali Ghati, The Star Chamber, and Observer Effect. They sold like hotcakes. I did pen sketches for any Delta Green Patreon backer that stopped by, and let me tell you, I didn't expect 60+ of you to be there—but it was great (though my hand may not agree, currently).

We had a magnificently packed Delta Green meetup (audio coming soon), where we spoke at length about the state of Delta Green, answered questions, and made some announcements.

The biggest announcement has to do with the form of Delta Green: The Role-Playing Game. We’ve been planning it as a single book, but it’s huge, and the cost of shipping it to ports far and wide called for careful consideration.

The options were:

  • Print a single book with 500+ pages. That would have made the book so heavy that delivery to backers outside the U.S. and U.K. would have cost up to $50 on top of what’s already been paid. 
  • Or make Delta Green: The Role-Playing Game a slipcase of two books. That contains a 192-page Agent's Handbook and a 320-page Handler's Guide. The Handler's Guide is the giant manuscript we circulated a few weeks ago, minus the rules portions that appeared in the Agent's Handbook. So, one book has rules, sanity and character creation: the Agent's Handbook. The other has monsters, magic, creating your own Delta Green, and the timeline: the Handler's Guide.

We chose option 2 for a lot of reasons. Most importantly, it reduces the international delivery costs dramatically. Our international-fulfillment partners in the U.K. can ship two separate packages—one with with the Handler’s Guide; the other with the Agent’s Handbook and the slipcase itself—for far less than shipping a single package the weight of a single, huge book. It’s a weird vagary of the way the Royal Mail handles parcels.

In option 2, no one pays any additional shipping. OK, truth be told, there are additional shipping costs, but they’re modest enough that we at Arc Dream can cover them. Backers don’t have to pay anything extra.

The fans at the Delta Green panel were happy with the announcement, and so were we. It's the best of all worlds.

So, long story short, if you ordered the “Case Officer's Handbook” option, you'll get Delta Green: The Role-Playing Game: the Agent's Handbook and the Handler's Guide in a beautiful slipcase, delivered in two packages, at no further shipping cost to you.


Thanks for all who came out.

Madness and miracles

Croaker Jr : So when is the next big release coming out, eh? ;)

SGlancy12 : Well, next year Chaosium has authorized three CoC books for Pagan.

SGlancy12 : The next DG book will incorporate the Cult of Transcendence, and a whole bunch of scenarios,

SGlancy12 : including the one you're playing in today.

SGlancy12 : It may be at the printer by February (rough guess).

SGlancy12 : Who here played in "The Army is Coming" last time?

KJPotter : I did. Had a blast!

Croaker Jr : Sounds good... I missed "Army" due to work.

SGlancy12 : The Shans and their PISCES pawns may also make an appearance in the next book.

SGlancy12 : Okay gents, let's get going here. I've got to go around 7:00pm.

SGlancy12 : We won't get this done in one session, but that's no reason to waste time.

SGlancy12 : Everyone got their briefing?

—Adam Scott Glancy (SGlancy12) hosted a playtest of the scenario “Dead Letter” in an America Online chatroom in August and September 1997. The players were Shane Ivey (CroakerJr—that was me), Keith Potter (KJPotter), and Patrick Grindle (PGrindle). “Dead Letter” would be published in Delta Green: Countdown in 1999. The Cult of Transcendence appeared in Delta Green: Targets of Opportunity in 2010. Digital archaeologists unearthed the full series of transcripts in an ancient hard drive.

Join Us at Gen Con

Will you make the pilgrimage to Gen Con this week? Find us at Booth 431. We have a lot going on.

Get in the ring for WRESTLENOMICON. That’s our upcoming card game of world-stomping tentacle fights, Old One-style. Wrestlenomicon was designed by Dennis Detwiller, Rob Heinsoo, and Shane Ivey and illustrated with gruesome glee by Kurt Komoda. Playtesting begins right after Gen Con, so sign up now. And come to Booth 431 to try it for yourself. Call Hastur out — I hear you have to say his name three times — and see if you can stand up to the Elbow of a Living God!

Ask questions and trade war stories at the 90-minute Delta Green seminar, Saturday at 7:00 p.m., with Dennis Detwiller, Adam Scott Glancy, Kenneth Hite, Shane Ivey, and Greg Stolze. That’s in the Crowne Plaza, Grand Central Ballroom D.

Know anyone at Gen Con who could use a pile of Delta Green PDFs in a bad-ass collectible package? Tell them go to Booth 431 and ask for the Charnel Dreams CD. The booth staff will know what to do.

Join Aaron Vanek’s epic Delta Green LARP Thursday, Friday, or Saturday night. One ticket is officially available Friday. But show up anyway and bring generic tickets. If someone doesn’t come, you’re in! 

On Saturday, join your fellow Agents (or are they only enemies in disguise?) in a hunt for clues across downtown Indianapolis. A Delta Green agent needs your help opening a Green Box -- a crate full of operational supplies, including one that might save her life. Watch the Delta Green Twitter feed Saturday morning for the first clue.
