Scenarios

Several scenarios have been written specifically with Delta Green in mind. Due to DG's respect for Lovecraft and other Mythos originals, it is usually easy to adapt non-DG modern Mythos materials for use with DG agents, especially since the history of DG stretches back to Innsmouth.

## From the original creators

These are all complete and published specifically for Delta Green.

* In the original Call of Cthulhu sourcebook (1997):
	+ Puppet Shows and Shadow Plays: Hunting a murderous parasite in Arizona. Simple scenario intended for FBI agents prior to DG induction.
	+ Convergence: The mystery of Groversville, Tennessee, a UFO hotspot and source of a young killer in obvious pain.
	+ The New Age: The Greys use the Enolsis Foundation to protect the Accord, leading to a clear sign of the End Times. A brief campaign in two parts.
* In *Delta Green: Countdown* (1999):
	+ A Victim of the Art: Three inexplicable, extremely violent deaths in Glenridge, Long Island, NY. Simple sandbox scenario for one or two sessions.
	+ Night Floors: A Yellow Sign is found scrawled on a piece of paper in the apartment of a missing painter, Manhattan, NY. Remade for Impossible Landscapes.
	+ Dead Letter: A Karotechia mini-campaign with zombies, moving from California to Montana.
* PX Poker Night (2002, free): A few Air Force buddies, a friendly game of poker, a crashed UFO. By Dennis Detwiller. Includes pregenerated characters. Updated from CoC to the Delta Green rules in 2020 as a standalone publication and in Black Sites.
* In Delta Green: *Eyes Only* (2007):
	+ Artifact Zero: A Montana missing persons case with infectious radiation.
	+ A Night on Owlshead Mountain: Surveyors have gone missing in a Vermont forest, leading A Cell to recall a massacre in the area three years before.
	+ Holy War: In the immediate aftermath of 9/11, Great Old Ones and their powerful servants clash as DG follows a trail from Arizona to New York
* Future/Perfect (2016): A four-part campaign by Dennis Detwiller. The Permian returns to bite the present.
* Delta Green: A Night at the Opera (2018, collection of previously published scenarios)
	+ Reverberation (2017): A Nineties rave drug called Reverb is back on the streets, better and stronger than ever. Now, its users and dealers have started vanishing. The Agents must identify and stop the source of the unnatural drug before anyone else falls prey to it.
	+ Viscid (2018): Two days ago, a newspaper delivery driver found retired geneticist Tibalt Grieves dead outside his suburban home. Police found Grieves’ girlfriend dead in the house. A detective discovered a hidden lab, outfitted with bio-hazard scrubbers. A CDC specialist found unidentifiable samples—samples that indicated that *something* had gotten loose. When the sun rose, Grieves’ body began to smolder and disintegrate.
	+ Music from a Darkened Room (2017): Put a haunted house to rest, one way or the other. By Dennis Detwiller. Downloadable.
	+ Extremophilia (2017): A secretive research company has developed a miracle drug, only to learn that every miracle has its price. Delta Green agents may be the ones to pay it.
	+ The Star Chamber (2016): The agents must hear and adjudicate the horrific after-action report from another team—by way of playing out scenes from the earlier mission in between scenes of the present day.
	+ Observer Effect (2016): The agents investigate a cutting-edge physics laboratory that may have looked a little too deeply into the nature of reality. An index helps the Handler build broader connections between horrors in the campaign.
* Delta Green: Control Group (2019, collection of scenarios with pre-generated Agents)
	+ **Blacksat**: A simple satellite repair leads them to truths of mathematics and physics beyond all human wonder and fear.
	+ **Night Visions**: A diplomatic patrol takes them to Gath Valley, a corner of the country that everyone tries to ignore—a place of deep shadows and ancient hungers.
	+ **Sick Again**: Investigating a strange viral outbreak may expose them to threats beyond time itself.
	+ **Wormwood Arena:** The Agents must investigate the cult, perhaps even infiltrate it, and stop a catastrophic incursion before it begins.
* A Victim of the Art (2019): A serial killer is at work in quiet Glenridge, Long Island. Bizarre mutilations mark the victims of the “Glenridge Chiropractor,” as national news and the conspiracy theorists at *Phenomen-X* call the killer. Privately, the medical examiner is more troubled by residue found on the corpses: a pulpy, gray, organic substance that defies analysis.
* Delta Green: Black Sites (collection of previously published scenarios, plus a new one)
	+ PX Poker Night (2020): A few Air Force buddies, a friendly game of poker, a crashed UFO. By Dennis Detwiller. Includes pregenerated characters.
	+ Kali Ghati (2016): DG agents in Afghanistan search for a lost colleague along the border to Pakistan. By Shane Ivey. Distributed as a 2015 DGRPG Kickstarter campaign reward.
	+ The Last Equation (2011): A gifted university student guns down a family of total strangers, leaving behind a string of numbers that fills Delta Green’s researchers with dread. Can your Agents stop the next horrific slaughter?
	+ Lover in the Ice (2016): An apocalyptic ice storm has crippled Lafontaine, Missouri. The Agents must secure a forgotten storage facility packed with artifacts of past Delta Green operations.
	+ Sweetness (2018): Vandalism on a family home makes the police fear a hate crime. Delta Green recognizes the symbol for something worse.
	+ Hourglass (2020): A woman vanishes, screaming, in front of dozens of witnesses in a small Oregon town. Your Agents must find what killed her, stop the threat, and make sure no one else ever learns the truth
	+ Ex Oblivione (2019): Vicious murders stain the Arizona desert. Crazed words scrawled at a crime scene hint at Y’ha-nthlei and the sea. A handful of Agents have a chance to claim vengeance for ancient wrongs—or suffer it.
	+ The Child (2020): A traumatized child looks to the Agents for protection from voices that never cease.
* Impossible Landscapes (2021): A mind-breaking, multi-decade, four-part campaign centered around the King in Yellow. It also contains the most recent version of Night Floors.
* Jack Frost (2021): A rural Alabama valley has always been prone to severe cold snaps. On 22 DEC 1998, the worst “Jack Frost” storm in history hit the farming town of Willis. A lingering, otherworldy freeze and sudden flood killed dozens. The players, Agents of MAJESTIC, are tasked with dealing with it.
* Iconoclasts (2022): A team of Agents is brought to a scene of horrors all too real: Mosul in 2016, held by the self-styled Islamic State in a reign of depraved brutality. From a small base at the Kirkuk airfield, the Agents must research the horrors to come and prepare for a harrowing infiltration. This is a three-part mega Operation.
* From the Dust (2022): A team of Agents must investigate the three most recent disappearances and strange reports from the Gerritsen mansion. The moon darkens. Fears gather. The infants of Red Hook are hardly the only ones at risk.
* Convergence (2023): A remaster of the original scenario from its 1993 Unspeakable Oath debut and the 1997 for the Delta Green: The Conspiracy Kickstarter. Will be printed as part of the Incursions book for the same Kickstarter.

## Fan-made for Delta Green

There are a lot of false starts on the Internet, but the following fan-made scenarios are complete:

* The vast majority of our many Shotgun Scenarios.
* The many creation coming out from the Night at the Opera Contests.
* The various scenarios in the many issues of Whispers of the Dead, the free Delta Green fanzine.

### Complete

* Operation Contagion by Matt Cowger.
* The Death of Simon Michaels (PDF attached to this article) by Rik Kershaw-Moore. Takes place in England, but written pre-*Countdown*.
* Gold Top: 1971 by Dosmania (2022): A 200+ page campaign. An isolated part of England is home to massive nuclear power stations, nuclear weapons research facilities, Anglo-Saxon burial sites, ancient capitals now lost to the sea, and iconoclastic communities trying to carve out their own place in the sun. A force is stirring, a network of cultists long dormant have been prodded into action, and something terrible is being called.
* Spurro's New Life Fertility Campaign (2021): A string of scenarios centered around New Life Fertility (featured in Delta Green: The Labyrinth).
	+ Tenebris Capra (2021): A family murder-suicide with a sole survivor catches the attention of Delta Green when they heard the final words of the murderer "The Black Goat Comes." Originally shared on reddit here.
	+ Tainted Waters (2021): Delta Green Agents are called in when a Philadelphia funeral is interrupted by the transformation of the deceased into a foul gray goo. Originally shared on reddit here.
* Sign of the Judgement by Jin Cardassian (2022): Inspired by True Detective Season 1. When the evidence from the Dora Lange killing is digitized, an automated monitoring system flags the words KING IN YELLOW and CARCOSA. Delta Green intervenes under the cover of an FBI probe into a suspected drug cartel connection. Their objective is to determine if these words mean anything and, if so, contain it.
* Dream After Dawn, by Jin Cardassian (2022): One month after Osama Bin Laden's death, Delta Green investigate intelligence suggesting Taliban forces in Pakistan have captured a crashed UFO.
* Synchrony, by Jin Cardassian (2022): After a student disappears from a locked room at the University of Texas at Austin, Delta Green organizes a low-priority black op which may have world-altering consequences. [1]

### Incomplete

* War with Terror: Outline of a campaign set in occupied Iraq/Afghanistan.
* Age of Horus: Outline influenced by Jack Parsons and Aleister Crowley.
* Project CAMPAIGN: A DGML project to write a Delta Green campaign in 2012.

Many other campaigns have been suggested on the mailing list over the years, though the material on them is not yet collected in this wiki:

* New Cult of Cthulhu. The ancient cult reforms as an elite dedicated to sociopathic materialism. This idea prefigures the Cult of Transcendence, and late-2000s financial crisis. Message 18319.
* Black Brotherhood. The Iraq War was a smash and grab on Irem between rival Mythos cults. Message 18496.
* The Shan cross the Atlantic and infiltrate MJ-12 (and Delta Green) after the Accord breaks down. Message 18297 (copied into Delta Green after 9/11).
* War on Dregs. Delta Green attempts to ignite conflict between the Fate and other Mythos/crime groups, in particular the Disciples of the Worm. As things heat up, DG begins to use ghouls as infiltrators. Message 26272 and thread.
* Office #44 takes the role of the Karotechia and is wiped out by a DG operation in North Korea. Message 32308.
* Crossover with the X-COM computer game franchise, particularly *UFO: Enemy Unknown* (1994). The suggested backbone was an attempt at subjugation and religious conversion of the Earth by vengeful insects from Shaggai and their light-tolerant slave races, opposed by PCs as BLUE FLY soldiers in an uneasy alliance of some of the canonical organizations. Message 32362.
