* [[http://exterminatusnow.co.uk/2003-11-14/comic/meet-the-crew/not-this-time/ Early on]] Harry and Eastwood decide they're not going to do "[[Series/MontyPythonsFlyingCircus the Python gag]]" just [[http://exterminatusnow.co.uk/2007-10-27/comic/shades-of-black-and-white/timing-is-everything/ yet]].
* A caption-contest strip in which Virus informs us "[[VideoGame/BadDudes Ninja have kidnapped the President, and we're not bad enough dudes to save him!]]"
* Another guest strip had the cast doing a parody of ''Series/FatherTed''.
* [[https://web.archive.org/web/20221130131820/https://superdickery.com/stairs/ Stairs.]] ([[Website/{{YTMND}} The one enemy]] [[ComicBook/XMen of the great]] [[http://exterminatusnow.co.uk/2009-12-13/comic/the-big-city/the-one-enemy-of-the-great-lothar-hex/ Lothar Hex]].)

* ''Series/MidsomerMurders'' is apparently still running in the far future.
* Lothar at one point mentions his "[[Webcomic/PennyArcade smouldering generic rage]]".
* [[Creator/JhonenVasquez FillerVirus]]!
* Though it's filler, there's a ''Franchise/{{Mas|sEffect}}''--[[http://exterminatusnow.co.uk/2010-04-11/comic/non-storyline/guest-comics/pixellated-you-will-know-pain-eastwood/ ASSUMING DIRECT CONTROL.]]
** In canon, [[http://exterminatusnow.co.uk/2011-10-03/comic/non-storyline/randoms/assuming-indirect-control/ Assuming Indirect Control]], (CABAL is a network of individually non-sentient [=AIs=] that are collectively self-aware, does that sound familiar to you?)
* [[http://exterminatusnow.co.uk/2011-10-31/comic/non-storyline/holiday-comics/kicking-bishop-zuviel-up-the-arse/ And here]] we have Eastwood in [[Franchise/MassEffect N7 armor]] and Rogue as [[Franchise/StarWars Luke Skywalker]].
* A [[ComicBook/{{Hellboy}} Mignola]]-[[Creator/BrianClevinger Clevinger]] [[http://exterminatusnow.co.uk/2010-06-13/comic/voiding-your-warranty/any-questions/ equation is mentioned...]]
** As is the inventor of the apparently-{{Magitek}} [[KillSat orbital]] [[WaveMotionGun weapon]] called the Exterminatus platform: Ludwig von [[Characters/{{WarhammerSkaven}} Skryre]].
* This [[http://exterminatusnow.co.uk/2010-07-03/comic/voiding-your-warranty/monopolytheism/ mission]] has Eastwood packing a [[Film/{{Aliens}} pulse rifle]].
* Not to mention that the team encounter a number of [[VideoGame/HalfLife small, annoying insect-like creatures who like to ambush in confined spaces]].
** And [[http://exterminatusnow.co.uk/2010-05-30/comic/voiding-your-warranty/stay-behind-after-class/ Black Halo's test chamber]] is a dead ringer for the test chamber which kicks off everything that happens in the first Half-Life.
* Several to ''VideoGame/TeamFortress2'':
-->'''Lothar:''' [[http://exterminatusnow.co.uk/2010-08-08/comic/voiding-your-warranty/target-recognition/ Get behind me, doctor!]]
** Eastwood and Virus bribing someone dressed like TheMedic, right down to the hair-do. And who's a [[HerrDoktor German Shepherd]], in case it wasn't obvious enough.
** And a ''VideoGame/TeamFortress2''-style kill message appears when the "Antelope Bastard" gets hit by a train.
** A shady figure [[http://exterminatusnow.co.uk/2012-01-16/comic/the-bookend-of-unimaginable-power/international-man-of-mercenary/ hires]] obvious [[{{Expy}} Expies]] of the BLU team to [[http://exterminatusnow.co.uk/2012-01-23/comic/the-bookend-of-unimaginable-power/a-mans-home-is-his-fortress/ infiltrate]] the Inquistion. [[spoiler:They fail.]]
* From the second strip: Syrus is apparently called "the Virus". [[Film/ConAir Is his surname Grissom?]] (May or may not be accidental.)
* [[http://exterminatusnow.co.uk/2011-06-05/comic/the-cesspool/where-everybody-knows-your-name/ This comic]]. Let's see, we have [[Series/{{Firefly}} Jayne, Mal, and Zoe]], [[VideoGame/StarFox Fox, Slippy, Wolf, and Falco]], [[Franchise/{{Metroid}} Samus Aran]], [[VideoGame/FZero Captain Falcon]], ComicBook/{{Deadpool}} beating up [[VideoGame/TeamFortress2 a bear version of The Heavy with The Soldier close by]], [[Franchise/StarWars Han Solo and Greedo]], [[Franchise/StarWars Boba Fett]] fighting [[VideoGame/TeamFortress2 The Demoman]], ComicBook/{{Deathstroke}}, [[VideoGame/MetalGearSolid Snake]], the crew of the [[Anime/CowboyBebop Bebop]], [[Franchise/TheChroniclesOfRiddick Riddick]], ComicBook/{{Lobo}}, and... [[Series/{{Cheers}} Woody]]. Has to be the most ShoutOut-filled comic they've done so far. The creators are aware of this, and refer to it as "Cameo-verload".
* [[VisualNovel/AceAttorney BULL]][[http://exterminatusnow.co.uk/2011-06-18/comic/the-cesspool/healthy-skepticism/ SHIT!]]
* [[http://exterminatusnow.co.uk/2011-08-09/comic/the-cesspool/clobberin-time/ This comic]] has the obvious shout out to ComicBook/{{Deadpool}}, but the girl sitting at the table behind him is clearly [[WesternAnimation/MyLittlePonyFriendshipIsMagic Applejack]] and appears to be sitting across from Twilight Sparkle.
* In order to cover up the events that occurred in the cesspool, Eastwood ends up sending Schaefer on a wild goose chase after the head of eBay, named... Edward Bay. One panel shows Bay attempting to run down Schaefer, whilst driving a truck that looks exactly like [[Film/TransformersFilmSeries Optimus Prime]] minus flame decals. And of course, there's the [[StuffBlowingUp nod]] towards [[Creator/MichaelBay another Bay]], to go with it.
** It's also likely a shout-out to ComicStrip/SpyVsSpy with the idea of 2 individuals almost identical but for color scheme (one black, one white) trying to kill each other in a variety of ways.
* ''VideoGame/BioShock1'' gets a nod [[http://exterminatusnow.co.uk/2011-10-16/comic/non-storyline/randoms/serious-sandwich/ here]].
* The sword in [[http://exterminatusnow.co.uk/2011-12-20/comic/non-storyline/randoms/a-grim-dawn/ this]] comic is near identical in appearance to [[VideoGame/{{Darksiders}} Chaos Eater]], and its name (Soulmourne) is obviously an homage to the Lich King's weapon in {{VideoGame/Warcraft}}.
* [[Franchise/TeenageMutantNinjaTurtles Ninja turtles]] [[http://exterminatusnow.co.uk/2012-01-29/comic/the-bookend-of-unimaginable-power/predator/ attempt]] to [[http://exterminatusnow.co.uk/2012-02-06/comic/the-bookend-of-unimaginable-power/predator-two/ infiltrate]] the [[http://exterminatusnow.co.uk/2012-02-13/comic/the-bookend-of-unimaginable-power/appliances-vs-predator/ Inquisition]].
* The two chickens sacrificed to [[http://exterminatusnow.co.uk/2008-08-02/comic/mort-to-it-than-zombies/blood-bucket-now-only-9-99/ raise the dead]]? [[Franchise/ResidentEvil Jill and Leon]].
* Before that, they also come to a gate with a padlock. Virus's convoluted plan of opening the gate sounds very much like a puzzle from the same series. Meanwhile, Lothar [[CuttingTheKnot breaks the padlock]].
* [[Franchise/{{Predator}} "Get to da spectre!"]]
* In the comments section for [[http://exterminatusnow.co.uk/2012-09-02/comic/the-bookend-of-unimaginable-power/step-four-profit/ this strip]], Virus states that the user names in the Website/YouTube comments are shout outs to posters on the [[http://s8.invisionfree.com/Exterminatus_Now EN forum.]]
* [[http://exterminatusnow.co.uk/2012-09-09/comic/non-storyline/randoms/dark-dungeons/ The strip for September 9, 2012]] has a misguided preacher named [[ComicBook/ChickTracts Jack who happens to be a chicken]].
* [[http://exterminatusnow.co.uk/2012-11-11/comic/drink-the-cool-ade/the-smell-of-soda-in-the-morning/ This page]] contains shouts to Film/ApocalypseNow, and the commercial war between Coke and Pepsi. The page title contains a reference to the [[DrinkingTheKoolAid Jonestown Massacre]].
* [[http://exterminatusnow.co.uk/2012-12-03/comic/drink-the-cool-ade/cereology/ #436]] has Virus find [[ComicStrip/CalvinAndHobbes Chocolate-Frosted Sugar Bombs]] in the cereal isle.
** The last panel also portrays cereal {{mascot}}s Tony the Tiger (Frosted Flakes), Buzz (Honey Nut Cheerios), Toucan Sam (Froot Loops), Cornelius (Kellogg's Corn Flakes), and Coco (Cocoa Krispies) as executive board members of "Big Cereal".
* [[http://exterminatusnow.co.uk/2012-12-10/comic/drink-the-cool-ade/box-quote/ Lothar with a box of cereal]] is surprisingly similar to a certain [[VideoGame/SilentHill2 infamous monster]].
* "It... it's ''people''! '''[[Film/SoylentGreen THE LIME COOL-AID IS PEOPLE!]]'''"
* [[http://exterminatusnow.co.uk/2013-03-23/comic/non-storyline/randoms/building-a-better-rat-trap/ Eastwood builds a life-size version]] of the board game ''Mousetrap''.
** Including a scene from ''Film/IronMan2''.
* [[http://exterminatusnow.co.uk/2013-04-26/comic/non-storyline/randoms/the-big-one/ Here]], Rogue's laser sword goes [[Literature/{{Jabberwocky}} snicker-snak]].
* [[http://exterminatusnow.co.uk/2013-03-31/comic/non-storyline/randoms/the-porcelain-firing-range/ Lothar uses the sniper rifle]] from ''Franchise/{{Halo}}''.
* Virus and Rogue visit [[http://exterminatusnow.co.uk/2013-07-16/comic/the-phone-book-of-the-dead/tldr/ a shop]] apparently run by [[Franchise/CthulhuMythos Nyarlatothep]].
* The [[http://exterminatusnow.co.uk/2013-08-03/comic/the-phone-book-of-the-dead/he-sells-sea-gods-neath-the-sea-shore/ network of demon gates]] under a city full of old bookstores is just [[UsefulNotes/TheLondonUnderground a tad familiar.]]
* [[TabletopGame/{{Warhammer40000}} Tzeentch]] apparently [[http://exterminatusnow.co.uk/2013-10-26/comic/non-storyline/randoms/ch-ch-ch-changes/ sued the Patterner]] for copyright infringement.
** [[http://exterminatusnow.co.uk/2014-01-18/comic/non-storyline/randoms/everchosen/ Though evidently it went back further than that.]]
** The Everchosen in that strip mirrors the ascension of Archaon in ''TabletopGame/{{Warhammer}}'' (minus the whole [[spoiler:squashed under a dropship part]]).
* Creator/MCEscher: After a ScoobyDoobyDoors scene, [[http://exterminatusnow.co.uk/2014-07-13/comic/tangled-web/time-and-relative-dimensions/ this page]] features a textbook example of Escher's {{Bizarrchitecture}} multi-directional stairwell room.
* [[http://exterminatusnow.co.uk/2015-08-05/comic/tangled-web/ritual-twenty-three-nineteen This strip]] has the PKE Meter from {{Franchise/Ghostbusters}}.
* The opening lines of the main page are referenced in [[http://exterminatusnow.co.uk/2012-04-22/comic/non-storyline/randoms/convention-flyer-one/ the header of this strip]].
* Inquisitor Kortez is an expy of [[Series/AncientAliens Giorgio A. Tsoukalos]], what with his [[http://exterminatusnow.co.uk/2014-01-02/comic/non-storyline/randoms/lunatic-fringe-fest/ lecture]] on spider-motifed artifacts possibly being linked to aliens.
** Eastwood likewise quoted the "Listen, I'm not saying it was aliens. But it was aliens." meme almost word-for-word a year earlier [[http://exterminatusnow.co.uk/2013-01-06/comic/drink-the-cool-ade/strange-brew/ here]].
* When Morth sent out some of the Patterner's GiantSpider demons [[http://exterminatusnow.co.uk/2007-09-21/comic/shades-of-black-and-white/famous-last-words/ here]], one of his cultists was riding one cowboy-style and yelled, [[Film/DieHard "YIPPEE-KAY-AY MOTHERFUCKERS!"]]
