* GainaxEnding: In ''Impossible Landscapes'' if the players are unable to escape the masquerade [[spoiler:the King In Yellow will be unmasked revealing the truth of the universe. The party's attendants will then rush the Agents, strip them naked and dress them in stage clothing and make-up; they will be taken to a stage. As the curtain opens it will reveal every PC and NPC encountered during the campaign and they will clap; the Agents will then realise they are wearing the same clothes they had in 1995 when they first met investigating the disappearance of Abigail Wright, and the back curtain will open to reveal the set: Abigail's room in the MacCalister building, where the Agents were 20 years ago. Moseby will mouth the lines, the same which the agents said long ago. The Agents are now forever part of the play they created. The Handler finishes by reciting a poem, and then the curtain closes.]]

** The Vagnoptus Manor, the headquarters of the Cult of Transcendence. From outside it looks like an abandoned mansion, you can find it on a map located just outside Stockholm, and also its property or tax records too. However, the architecture of the manor is formed with AlienGeometries, and walking through the halls of the Manor in the right way will eventually result in ending in the "Nightmare mansion", an alternate version of the mansion ([[MindScrew or it's still is the same mansion, maybe]]) that is ''in orbit of the [[PrimordialChaos court of Azathoth.]]''

** Controversy over the Tcho-Tcho being racist YellowPeril caricatures have led to later games to leave the door open as to if they're just another Southeast Asian ethnicity, a completely monstrous and inhuman race that are only vaguely human, the complicit cultists they are normally portrayed with, or even some form of the two, where the Tcho-Tcho who are Eldritch villains are simply ethnic Tcho-Tcho turned cultists.

* Area51: One of Majestic-12's facilities is in Area 51, although it is not Area 51 itself.

* SpellMyNameWithAnS: ''Delta Green'' uses slightly different spellings for some familiar Great Old Ones: Itla-shua (Ithaqua), Qu-Tugkwa (Cthugha), Tleche-Naka (Atlach-Nacha), Giliszta (Glaaki) and A-Abhi (Abhoth).

* PretentiousLatinMotto: Delta Green's in-universe unofficial motto that shows in their logo is ''Scientia mors est'', [[TheseAreThingsManWasNotMeantToKnow "Knowledge is death"]].

--> [[spoiler:[[WhamLine Only one of us has ever left the party.]]]]

* TomatoInTheMirror: In ''Impossible Landscapes'', in the Dorchester House players meet a mental patient named "Sunshine" aged around 80 with androgenous characteristics and strange similarity to the agents, they are completely mute but becomes excited and desperately attempts to communicate when they see the agents. But all Sunshine says and writes is gibberish. [[spoiler:At the end of the Masquerade, the King in Yellow can envelop an Agent in its cape and they will find themselves in front of an audience in 1930's New York. The Agent will soon discover anything they say or write is gibberish, soon they are taken to a mental asylum where the nurses nickname them "Sunshine".]]

** Majestic's Steering Committee had always a few internal divisions over whether the accord with the Greys was beneficial or not. These divisions became extremely prevalent during the Delta Green-[=MJ12=] secret war. It took one rogue element ([[spoiler: counterintelligence director Gavin Ross]]) and a bit of luck (with the 9/11 attacks) to take Majestic down.

** Karotechia itself is formed by three men, however, they managed to covertly achieve control of ODESSA (A secret organization of escaped nazis) and to employ neo-Nazis, white supremacists, anti-zionist terrorists, mercenary, and criminal groups, collectively referred as the ''Bauern'' ([[{{Mooks}} Pawns]]), to work for them. They also have ''Die Untoten'' ("The Living Dead"), old deceased Nazis and war criminals back to life to join their ranks.

* TheOmniscientCouncilOfVagueness: The setting is filled with these

* MotiveDecay: What leads to Majestic-12's demise; some elements inside it started to see that MJ-12 degenerated into a quasi-CargoCult that worshipped Grey technology for its own sake. Eventually those who thought like that worked to take down Majestic from the inside (Such as Gavin Ross) with the help of Delta Green and turned into The Program.

* MysteriousStranger: The Handler is recommended to make Stephan Alzis be this, sometimes appearing in StealthHiBye and giving the [=PCs=] some advice or support while keeping the reasons for it mysterious.

* InterfaceScrew: The ''Impossible Landscapes'' campaign book starts as any other, but as you progress things start getting...strange. In the first few chapters you start to see strange annotations, words circled to form an anagrams and ominous notes for the reader. As you go through the chapters, you start to see more derranged art, certain words have their font changed, anything related to the King in Yellow features a completely surrealist layout compared to mundane scenes with the standard layout, and by later chapter the book gets positively colorful and harder to read.

* IAteWhat: The antagonist of CONTROLCOPY will actively attempt to trick the PCs into eating human flesh, potentially leading to this reaction.

** [[spoiler:Hastur. Unlike vanilla ''Call of Cthulhu'', Hastur is not a God or Old One, but an infectious and pervasive force of decay. Knowing about Hastur or its related mythos trappings allows such decay to happen on a person's psyche, and "infected" people will become a vector in spreading Hastur's influence. Even worse is that it can infect ''places'' too, which also become [[AlienGeometries "insane" in their own way]]. Both places and people can infect eachother and vice-versa, until they are affected enough and get pulled to Carcosa. In ''Impossible Landscapes'' it's reflected by the Corruption mechanic.]]

** MAJESTIC's NotSoOmniscientCouncilOfBickering is divided between two factions: One which seeks to maintain the Accord with the Greys, and another which seeks to expose the Grey's true intention's and end The Accord. The pro-Accord faction starts with a huge political power -- due the Grey's providing a report of every single weapon of pro-soviet forces, which basically won the Cold War for America, and also richer due March Tech selling advanced Grey technology to the Military-Intelligence industry. When Delta Green strikes a series of successful operations against the mi-go and Majestic's operations, the Greys cease contact with [=MJ-12=], NRO Delta commander Adolph Lepus, along with the pro-Accord faction attempts a coup against Director Justin Kroft [[spoiler:(who is killed by Lepus)]], while a counter-coup is launched by the anti-Grey side led by Forrest James [[spoiler:(AKA Agent DARREN)]] with support of Operation BLUE FLY and Delta Green, successfully taking over MAJESTIC-12 and using UsefulNotes/TheWarOnTerror and UsefulNotes/{{NSA}}'s influence to reestablish DELTA GREEN.

** ''Delta Green'' to ''TabletopGame/CallOfCthulhu''. ''Call'' focuses on the the supernatural aspects of the mythos and its unnameable monsters, in fighting horrific [[EldritchAbomination Eldritch Abominations]] and their derranged cultist followers. ''Delta Green'''s writing on the other hand tends to be more tragic, nihilistic and hopeless. It leans a lot on the human side of it, with the sanity system mixed with the bond system emphasizing the spiral of self-destruction leading to some PersonalHorror. Likewise with the frequent "human" antagonists, with the powers of the Mythos merely enabling the already corrupt humans to do atrocities, and the conflict between the Agents and their employing organization: [[ToBeLawfulOrGood following orders or following their consciences]]?

* TheDanza: Each book that [=CptnSnshn=] introduces to potential Lonely is unique and always features a main character with the same first name as the Lonely. When a Lonely writes the manuscript of a second book, they join the Grim.[[invoked]]

* ConspiracyTheorist: Entire groups of them that keep appearing in Delta Green operations as they are closer to the truth then they imagine: Saucerwatch, Phenomen-X, the Dream Syndicate and the Human-Extraterrestrial Liberation Project (Or [[FunWithAcronyms H.E.L.P]] for short). [[spoiler:The latter is a Cult of Transcendence cover under the See of Hate; its purpose is to use UFO conspiracy theories to promote paranoia (fear of "Grey" invaders) and racism (worship of "Nordic aliens" as saviors)]].

*** The new edition compared to the old one. The original sourcebooks offered a slightly pulpy and fun, albeit still dark and edgy on their own right, takes on pop culture conspiracies, such as Roswell aliens, the Men-in-Black, Nazi occultism, the Illuminati and so on. The new edition however, has opponents be more real threats based on our modern worries and anxieties; ''The Labyrinth'' for example, has enemies based on right-wing radicalization caused by industrial decline and urban decay (The Sowers), the growing gap between the population and ultra-rich (New Life Fertility), radicalization of socially isolated people through the internet (The Lonely) and cults recruting desperate people by offering miraculous healings (The Prana Sodality).

** A real-life example in ''Iconoclasts'' is the Mosul Battalions against ISIS. The players can choose to use them as an asset but circumstances can led them to become hostile as well.

** "Dr." Olaf Bittereich of the Karotechia. He is not even a real doctor, but a con man pretending to be "medium" who was recruited into the Karotechia to help with research. He accidentally stumbled into a spell to contact "those beyond", on the activation he was contacted by the spirits of great German heroes and finally the Führer himself, now ascended as one of the Enlightened Masters. He commanded Bittereich to use the remnants of the Karotechia to start the FourthReich and elevate the aryans into an "ascended" race.

* LaResistance: The Army of The Third Eye, against the Shan.

* SealedEvilInACan: Several examples. Most notable is the [[NamesToRunAwayFromReallyFast Father of Knives]], a sentient storm of razor-sharp obsidian shards sealed in an urn... and inadvertently freed by ISIS militants looking for artifacts to loot or destroy.
