* Rei [[LightNovel/HaruhiSuzumiya is reading]] a copy of ''Literature/{{Hyperion}}''. The text quoted from the book, too, is almost certainly [[{{Foreshadowing}} meaningful]].
* There have been mentions of an alien race, with interest in alien artifacts, usually referred to as "the unknowable [[MagicalGirlLyricalNanoha Tsab]]", and one of their captured devices is called ''Bah'ri Diß".
* Mythos-related tomes that Gendo has acquired include several Creator/HPLovecraft stories, [[Comicbook/{{Watchmen}} The Tales of the Black Freighter]], and "the full product of that unknowing seer, [[LightNovel/HaruhiSuzumiya Nagura Tanigawa]]", which explains the relationship between Azathoth and Nyarlathotep.
** A series about a "[[LightNovel/HaruhiSuzumiya hyperactive nazzadi girl and her sardonic human male companion]]."
* The leaders from VideoGame/SidMeiersAlphaCentauri are the panellists on Series/QuestionTime. They speak almost entirely in appropriated SMAC quotes.

* A specific type of Aeon War Syndrome is known as [[Literature/HouseOfLeaves Navidson's Syndrome]]. It involves hallucinations of running down dark corridors.
* ''A result of attempts to provide more [[VideoGame/MetalGearSolid subtle technology for launching ICBMs]], the original project had been a failure due to [[VideoGame/MetalGear questionable decisions for a launch vehicle]] and the [[SciFiWritersHaveNoSenseOfScale energy requirements for trans-continental weapons]].''
* The Director of Special Services is called [[Creator/AlastairReynolds Khoury]], just as the head of the Achtzig Group is Dr Calvin Sylveste. That's a thing of such profound technohorror that it's traumatic to think of it.
** Special Services certainly do not employ [[Manga/{{Hellsing}} genetically modified dual-triple-quatro-whatever-wielding bayonet priests]] voiced by Creator/NorioWakamoto, since there is no Special Services to begin with.
* There are also numerous references to this very wiki, including naming tropes like HumongousMecha by name.
** Justified. @/EarthScorpion is OneOfUs, after all.
* "[[{{Exalted}} Christopher Salaam had gone crazy at the end, become convinced that the entire universe was a localised bubble in a vast churning sea of infinite possibilities.]]"
* One Migou [self/body-entity] maintains that the best solution is to [[Film/{{Aliens}} sterilize the place from from orbit, because it's the only way to be sure.]]
** Another Migou would like you to know that [[VideoGame/{{Prototype}} When this [deployment/force] will [hunt/locate], this [deployment/force] will [kill/exterminate]. No thing is [safe/inviolate], no thing is [protected/sacred]. As it stands, this [deployment/force] is the [last/final] line of [defence/containment]. This [deployment/force] will [burn/sterilise] itself to hold the [defence/containment] line.]]
*** In somewhat HilariousInHindsight moment, the above [meeting/assembly] unintentionally resembles DarkerAndEdgier [[GhostInTheShellStandAloneComplex Tachikomas.]]
* Dr [[Series/{{Firefly}} Simon Tam]] works for the Ashcroft Foundation, who just happen to run a [=R1VER=] project.
** The Reavers get a ShoutOut when describing the [[ReligionOfEvil Rapine Storm]]. "Words were not necessary to explain what that meant. The human Disciples, if the term could apply to those degenerates, would rape you to death, eat you and wear your skin as clothing. These actions could even be re-arranged."
* [[VideoGame/{{Portal}} Gladys Chell]] was transferred to Project Achtzig. EarthScorpion jokingly claimed that [[VideoGame/SystemShock Shodan von Braun]] is another employee.
** "The latter sentence, meanwhile, was as demonstrably as false as Cake's hypothesis on the nature of existence." [[StealthPun So]] [[MemeticMutation Cake is a lie?]]
* NEGN/NEGA doctrine is to enter "[[GhostInTheShellStandAloneComplex autistic mode]]" when engaging Migou forces, and the NEGN/NEGA deploy "Chalybion" helicopter drones with tail-mounted guns. These are nicknamed "Jigabaki" by the Loyalist Nazzardi..

* [[VideoGame/HalfLife HEV suits]] are mentioned.
