I’ve been very fortunate to have a small role in the great success that is the Delta Green RPG. Having been a fan of the setting-turned-stand-alone game since soon after the publication of the first edition of Delta Green in 1997, I always enjoyed when new bits and pieces for the setting appeared in between the mammoth official books like Delta Green: Countdown and Delta Green: Eyes Only. Now that the older material is scheduled to be updated to the stand-alone Delta Green game itself (see the Kickstarter here), I thought I might make a list of the various places DG has appeared over the years outside of the core books (Delta Green, Delta Green: Countdown, Delta Green: Eyes Only, and Delta Green: Targets of Opportunity) since, as far as I know, only some of this material as part of the update (though I am hoping some of the later stretch goals prove me wrong.) This list builds off of one prepared by Shane Ivey on Arc Dream’s own site, but as he only covered up to issue 23, I thought I might expand upon his notes, focusing only on the items that include some overt Delta Green content.
As a side note, all of the issues from 16/17 on are available for general sale (though I’m not sure how many hard copies of 16/17 are left) and issues 18+ are available in print and PDF on DriveThruRPG.
In a future post I will look at the Delta Green content other products and (likely even later) items that, while not explicitly written to be part of that setting contain some elements that would make them very suitable for such use. NOTE: Adam Scott Glancy’s running column about Delta Green, “Directives from A-Cell”, which ran in both Worlds of Cthulhu and issues 20-25 of the Unspeakable Oath, will be summarized in a future installment.
Unspeakable Oath 7 (Fall 1992)
“Convergence” by John Scott Tynes
This scenario is the first time that Delta Green is mentioned in print and predates the setting book by five years. It later appeared in the core Delta Green book in a highly revised version – the Yog-Sothoth wiki page for the scenario offers a very clear breakdown of the changes between the two. This original version of the scenario was intended to be part one of a two part set of pair scenarios, with the other scenario, “Transference”, which appeared in the Cyberpunk RPG magazine Interface.
Issue 7 of the Unspeakable Oath is only available on the secondary market. Sorry.
Unspeakable Oath 14/15 (1997)
“Fuel of the Gods” (by Michael Cisco)
The first Delta Green related content to appear in the Oath after the publication of the setting book, this involves some experimental petroleum and the rather dire effects produced therein. The Delta Green element was more of an option and not the core of the scenario. Here is the summary page on the Yog-Sothoth wiki. This one, again, is only available on eBay or the like.
(The scenario “Call of Duty”, by Dennis Detwiller, in that same issue is not written for Delta Green but some of the plot of the scenario connects it to his creation “The Fate”.)
Unspeakable Oath 16/17 (2001)
“See No Evil” (by Adam Gauntlett)
This scenario (which I hope somehow is updated as part of the current Kickstarter) features an a Delta Green team surveilling the attendees of a conference of Holocaust deniers and some of their new “friends”. This scenario is definitely set up as a Delta Green operation and discusses how the agents can be integrated into the investigation and the complications their covert status causes as well as some options for covering up any… incidents that happen along the way.
The “Tale of Terror” about the disappearance of Col. Fowcett (by Daniel Harms) includes a Delta Green option among its trio of possible mysteries.
“See No Evil” remains a favorite scenario of mine. Amazingly you can still get copies of issue 16/17 in print from Arkham Bazaar!
Unspeakable Oath 18 (December 2010)
Slight Return (by Pat Harrigan)
Another Tale of Terror written for the Delta Green setting. It involves a resurrected (in a way) agent.
Unspeakable Oath 19 (March 2011)
Bernice Cartfield: a Delta Green Antagonist (by Greg Stolze)
Something of a rarity, this is a new NPC suitable for Delta Green. Cartfield can serve as a shady friendly, a rival, or even an enemy of the conspiracy.
Unspeakable Oath 20 (June 2011)
“Let’s Learn Aklo” (by James Haughton)
This scenario was the 2010 winner of the Shotgun Scenario contest on the Delta Green Mailing List.
The Arm in the Green Box (by Bret Kramer)
Something left behind in a Green Box proves dangerous to the agents who visit it later. Ooops.
“Directives from A-Cell” – see this list of entries at the bottom of this article for more information.
Unspeakable Oath 23 (August 2013)
“Cold Dead Hand” (by Adam Scott Glancy)
This scenario, set in 1991 and featuring members of Spetsnaz combating the Mythos during the failed Russian coup of that year, takes up a whopping 53 pages (out of 82) in this issue and is the first scenario (outside of Paranoia) where I can recall the players having access to nuclear weapons.
Unspeakable Oath 24 (July 2014)
This issue has a bumper-crop of Delta Green content, starting with a trio of Shotgun scenarios….
“Agent Purple’s Green Box Blues” (by James Haughton)
“Holding Cell” (by Bret Kramer)
“Secret Shopper” (by Ed Possing)
These were the Shotgun scenario contest winners from 2011, 2012, and 2013 respectively.
The Cult of A (by Bret Kramer)
This was my take on a Hastur cult, by way of the online pro-Anorexia/Bulimia movement. It probably has a bit too much of the Derlethian take on Hastur to work in a post Impossible Landscapes Delta Green world, but I like it (and think it would have worked even better if I had the chance to include some impact of the cult on Home scenes… but those didn’t exist yet…)
Unspeakable Oath 25 (July 2018)
This issue has four(!) Shotgun Scenario contest winners:
“Die Nachtbruder” (by Chris Huth)
“Operation STOP REPO” (by Kevin Hams)
“Polybius” (by Viktor Eikman)
“The Third-Man Factor” (by Will Schar)
These were the 2015, 2017, 2014, and 2016 winners respectively.
In addition to these short scenarios there was a long Delta Green scenario as well as two articles:
“Secondary Infections” (by Pat Harrigan)
This oft-overlooked scenario bring Delta Green to New York City to investigate a possible sighting of a long-dead hostile party. SPOILERS – As this scenario includes the Tcho-Tcho, it might be useful in conjunction with the DG scenario Reverberations.
Spawn of Tleche-Naka (by Dennis Detwiller)
For legal reasons this article’s dreadful spider monsters are unrelated to Atlach-Nacha. That does not make them any less terrifying, especially for those with insect phobias.
Armed at the Opera (by Hans-Christian Vortisch)
A summary of usual weapons and equipment tactics for the typical Delta Green agent.
