History Trivia / Doom

*** ''Back to Saturn X'', a series of ''Doom II'' megawads created by the Back to Saturn X Team that features exclusive textures set, original music, and a new colormap and palette. Its title, episode names, and map names are named after albums and songs from Music/GuidedByVoices along with titles and song lyrics being incorporated into the text screens. The first episode received a Cacowards in 2013 and while its second episode received one in 2014. The official curated version of the megawads had their references to Guided by Voices altered and its title {{officially shortened|Title}} to ''BTSX'' with each episode using [[FunWithAcronyms joke acronyms]] on their respective title screens.

*** ''Earthless: Prelude'', a 12-level mod for ''Doom II'' crated by James Paddock with new skies and sprites by Fuzzball. It is the {{spiritual successor}} to his previous mod, ''Deathless''.

*** ''Revolution!'', a ''Doom II'' megawad created by Thomas van der Velden. In 2016, musicians in Doomworld forums led by James Paddock collaborated on a MIDI Pack for the mod with a new level added by Thomas van der Velden. The curated version features the MIDI Pack built-in with along with a number of changes to the maps and soundtrack. Originally this add-on was supposed to release in 2021 before Arrival and Anomaly Report, as its internal add-on folder and file name is designated as "14", but [[ScheduleSlip it ended up releasing later into 2022]].

* DivorcedInstallment: The game was initially planned to be a licensed title based on ''Film/{{Aliens}}'', but iD Software pulled out of negotiations with 20th Century Fox over concerns about the team's creative freedom. They opted to turn the idea into ''Doom'', mixing influences from ''Film/EvilDead2'' and a ''TabletopGame/DungeonsAndDragons'' campaign they had recently finished.

*** According to Aubrey Hodges, the person who created the sounds and music used for PSX Doom, the Archvile was planned to be in PSX Doom, and he even created new sounds for the Archvile, before the Archvile was removed from the game when it proved too memory-intensive for the Playstation's RAM while the developers were unwilling to compromise the Archvile to include it. All instances of the Archvile in the included Doom 2 maps were replaced with a hanging meat hook texture.

** Several possible player characters were planned, who had their own strengths and weaknesses (one was good with bullet-based weapons and dealt good damage, but did worse with missiles; one was a JackOfAllStats with low speed; one was fast and good with the pistol, but didn't do well with the bayonet and recovered less health from medkits; and one was fast and evasive, and good with the bayonet, but had low health), as were [=NPCs=], particularly "Buddy Dacote", who would have disappeared during the initial nastiness at the beginning of the game, reappearing at the end of the first episode [[SacrificialLion only to be brutally murdered by a demon]] (hence his last name, which was an acronym for "dies at conclusion of this episode"). At best, the release version of the Doomguy bears a resemblance to Dacote, sharing a similar backstory (Buddy was reassigned to Tei Tenga for showing up a superior, Doomguy was reassigned to Phobos for assaulting a superior) and a similar fate (dies at the end of Episode 1, though Doomguy fights his way back out of Hell across the second and third episodes). The game was also planned to have six episodes, the same as ''Wolfenstein 3D'' ended up with, though past the first one little is known about any of them other than their names (with the planned third episode lending its name to the released first episode), and the released game has only ended up, at most, with five (three included in the original release, ''Ultimate Doom'' adding a fourth, and Creator/JohnRomero much later creating ''SIGIL'' for the game's 25th anniversary to act as a fifth episode).
** The game's source code includes DummiedOut lines that would have allowed for the doors in the two ''Wolfenstein 3D'' maps to open to the sides as they did in that game rather than opening upwards like they do normally. It would not be possible to replicate that sort of behavior on the ''Doom'' engine until the version that ''VideoGame/{{Hexen}}'' was built on introduced polyobjects.

*** ''REKKR'', a Norse and Celtic-themed total conversion for ''The Ultimate Doom'' created by Matthew "Revae" Little. It received a Cacoward in 2018. There are some {{bowdleri|se}}zation in the curated version as the valkyrie statues are clad in armor when they were originally nude, however, the author does not mind the change the and preferred the look of the armored statues. The mod would go on to have a standalone UpdatedRerelease in the form of ''REKKR: Sunken Lands'' through Steam on October 11, 2021 and the ZOOM Platform on December 22, 2021, bundled with a modified version of [=GZDoom=] and features a canonical fourth episode in place of the bonus levels from the original mod. A fan of the game created a mod that restores bonus levels back into its re-release, and Revae has [[ApprovalOfGod pinned the download for the mod on the game's Steam forums]].

* ExecutiveMeddling: The [[PortingDisaster infamous]] Saturn port is a result of this. It originally used the Saturn's 3d hardware, resulting in a better looking and more advanced port than the original PC version. However, Carmack wasn't a fan of the system's 3d rendering style, particularly the fact that it resulted in some texture warping, so he demanded the game was redone with software-based rendering. The result was a rushed port that ran on a low resolution and had a poor framerate because the only option they had the time for was hastily ripping out the Sega 32X's software renderer and running it on hardware it wasn't designed for.

** The reason the [[UsefulNotes/ThreeDOInteractiveMultiplayer 3DO]] port of the game was [[PortingDisaster so lousy]] was because [[https://github.com/Olde-Skuul/doom3do it was programmed by]] ''one woman'', who was forced to rush out at a breakneck pace of ''ten weeks'' by a company head who had no idea what went into porting a game between platforms (she was only given a PC copy of ''Ultimate Doom'' and some JPG assets to start working from). On top of that, the publisher decided to have 250,000 copies of the game printed; it only managed to sell '''10,000''' copies, meaning that the port ended up proving a CreatorKiller as well.
** The UsefulNotes/SegaSaturn port got hit with this as well. Originally, developers Rage Software created a custom engine that made full use of the system's formidable 2D rendering abilities, and would have run at double the frame rate of the [=PlayStation=] version while losing only a couple of graphical features. Unfortunately, John Carmack of all people vetoed the use of this engine, as one of the downsides of using the Saturn in this way was texture distortion, [[ForWantOfANail which was a deal-breaker as far as he was concerned]]. This resulted in the development team having to hastily tear out the rendering engine from the previous [=32X=] version (the Saturn used the same CPU and a very similar graphics chipset to the [=32X=]) and slap it in, resulting in the finished product suffering from poor performance and noticeably inferior visuals to the [=PlayStation=] version.

* BoxOfficeBomb: Budget, $60 million. Box office, $55,987,321.

** The film is also this for Creator/DwayneJohnson. In a 2009 interview, he described the film as an example of "trying and failing" to do a good video game adaptation as well as a cautionary tale of what "not to do," and also [[https://twitter.com/TheRock/status/984852480587513856?s=19 called the movie a stinker on Twitter]] while promoting ''Film/{{Rampage|2018}}'' ([[https://twitter.com/DOOM/status/984879084101566466 to the chagrin]] of the official ''Doom'' Twitter).
** Creator/RosamundPike [[https://www.youtube.com/watch?v=ZfXszavE4Ig&ab_channel=ColliderExtras went on the record in 2021]] stating that she feels some embarrassment and guilt over the film's outcome since she believes she didn't do sufficient background research into the ''Doom'' world and what it meant to fans.

!Comicbook

*** ''Deathless'', a ''Doom'' megawad created by James "Jimmy" Paddock that was originally developed under the name ''Griefless'' as Episode 4 replacement until it expanded into a full game replacement as part of [=NaNoWADMo=] (a play on National Novel Writing Month where WAD authors create a WAD "from stretch" in 30 days). It received an award on the 2017 Cacowards.

** The Chinese title, still used to this day, is ''Huǐmiè Zhànshì'' ("the annihilating soldier").

* AbsurdlyShortProductionTime: The much-maligned UsefulNotes/3DOInteractiveMultiplayer port was infamously put together in just ten weeks. According to Rebecca Heineman, the sole staff member for the port, the CEO of Art Data severely underestimated the amount of time and effort that game development required, even for porting.

* FandomLifeCycle: The classic ''Doom'' games seem to be in stage 6a, with an active community.

** A CaptainErsatz of the comic book version of Doomguy appears as a boss fight in ''VideoGame/KingdomOfLoathing'' 's Zombie Master [[PrestigeClass challenge path.]]

* FanNickname:
** A lot of fans refer to the pair of Barons of Hell that serve as the [=E1M8=] boss fight as the Bruiser Brothers, which was also id's internal name for the pair.
** For a long time, the protagonist of the original series never had an actual name and was referred to as "Doomguy" by the fans. It was not until the release of the novels was he finally given a real name: Flynn Taggart.
** Doom II RPG, however, names him Stan [[VideoGame/Wolfenstein3D Blazkowicz]], thereby making the hero a descendant of VideoGame/CommanderKeen as well. If the Doom RPG series wasn't [[StrictlyFormula yet another standalone continuity]], this could be accepted as an official name.
** On the contrary, though, [[WordOfGod John Romero]] has stated that, despite how the novels as well as the above spin-off attempt to shoehorn a name in for the "Doomguy", this protagonist has no canon name as he is supposed to represent the player themselves.
** Some fans have referred to the sentry droids from ''Doom 3'' as [[VisualNovel/{{Snatcher}} Metal Gear]].
** "Flame boi" for the Arch-Vile, which comes from a humorous GameMod that replaces all sound effects with a [[SyntheticVoiceActor text-to-speech program]] SayingSoundEffectsOutLoud. Said mod translates the Arch-Vile's "spotted player" sound with "here comes flame boi".
** "Agitating Skeleton" for the Revenant, thanks to the [[https://www.youtube.com/watch?v=HJcf0aOwmiA PRO DOOM MONSTER STRATS]].
** Cacodemons are often called "tomatoes", owing to their bright red coloration and roundness. They're also sometimes called "meatballs", but that name is more often used for Pain Elementals for their brown hue.
** ''Silent Doom'' for the Atari Jaguar port, coined by ''WebVideo/TheAngryVideoGameNerd'' because it has no music.
** The fanbase frequently refers to the first four releases in the series (''Doom'', ''Doom II'', ''Master Levels for Doom II'', and ''Final Doom'') by the collective name of "classic Doom" or "Doom Classic", since the graphics and gameplay are so similar amongst them that they could easily be viewed as just one big game, and especially since most [=WADs=] (the backbone of the community) use assets from all of them. ''Doom 64'' is also sometimes included in this set, since it uses the same engine, but not quite so universally, as it does actually have new graphics and altered enemy behaviors, and until 2020 was exclusive to a different platform.

** There was also the BFG. The classic BFG is probably the most complicated and illogical weapon ever put in an FPS, largely due to it holding over all of the mechanics from a scrapped alpha version of itself. This "billion fireballs gun" fired a ragged burst of 40 projectiles and was scrapped because it "looked like Christmas" and slowed the game to a crawl. The ''Doom'' BFG might appear to just fire a big ball that does splash damage, but it actually does this:
### After a delay of just under a second, the BFG fires the green energy ball.
### On impact, the projectile deals a large amount of direct (not splash) damage to whatever it hit.
### The BFG's invisible mechanics come into play now. The weapon fires a spread of 40 hitscan "traces" (or "rays") evenly distributed across a 90-degree arc pointing in the direction the BFG ball was fired in, ''from the player's current position''[[hottip:*:which allowed for some multiplayer shenanigans until it was patched, such as shooting the BFG into an empty room, then peek down a different corridor in time with the projectile colliding, doing a OneHitKill to everyone in said corridor instantly]], with each ray dealing 15d8 damage. Coupled with the average damage of impact being 450 damage, the average damage of the BFG (with very little deviation, due to the ''601'' dice rolls) was 3150 damage. [[CurbstompBattle This is 150 more health than the final boss of Doom has.]]
*** Most people are not aware that you can kill someone with the BFG with your back to them after firing it in a totally different room.
*** More traditionally, the BFG is dummied out from the UsefulNotes/{{Super Nintendo|EntertainmentSystem}} and UsefulNotes/Sega32X ports of the original game, because any maps (or areas in maps) where pickups for it actually appeared were cut.

** For Creator/DwayneJohnson. [[https://twitter.com/TheRock/status/984852480587513856?s=19 He called the movie a stinker on Twitter]] while promoting ''Film/{{Rampage|2018}}''.

* FakeAmerican: Creator/KarlUrban (New Zealand) and Creator/RosamundPike (British) as siblings John and Samantha Grimm.

** As various documents including the Doom Bible have indicated, Doom shifted from originally being conceived as a tie-in to the film Aliens, later an original sci-fi story filled with more detailed plot, and finally the initial stages of its final form as an all original sci-fi FPS. Tom's notes in the Doom Bible also indicate that he carried certain references (such as character names) from Doom's rough draft into his own original game ''VideoGame/RiseOfTheTriad''. However, ''Rise of the Triad'' is more of a spiritual successor to ''Wolfenstein''.
