View source for ID multiverse timeline (Doom 3 as prequel)

==Background==
This is similar to the [[ID multiverse timeline (Doom 3 as sequel)]] except that the dates for Doom, Doom II, Final Doom, and Doom 64 are set in the 22nd century, as implied by the events of Doom RPG and its website (and the Doom 3 BFG Edition) (rather than in the 21st century as per Doom for SNES, and implied by the [[Doom novels timeline]].)

It is based on the idea that Doom 3 is an interpretation of the backstory given in the Classic Doom's manual, about the soldier (see [[Marine (Doom 3)]]) who was court martialed and sent to Mars Base, with elements of the backstory given in Doom II manual.

At least one theory goes;
:The timeline of the DOOM series can be a bit convoluted, but basically everything up until DOOM 2016 featured Doomguy as the protagonist. DOOM 3, 1, and 2, in that order, chronicle his battle with the forces of hell. After those, DOOM 64 sees the Earth quarantine all of the UAC research installations, but a plot by the demons lures Doomguy back into hell once again. Serving as a cap on the story, at the time, DOOM 64 had Doomguy kill the Mother Demon and remain in hell to destroy demons until his last day.<ref>https://screenrant.com/doom-eternal-connects-1990s-games/</ref>

Depending on perspectives of Doom RPG and later manuals Doom's protagonist is the same character in practically every game in the series (Doom, Doom 2, Final Doom, Doom 64, Doom 3, and possibly even in Doom (2016). However this timeline allows for idea that [[B.J. Blazkowicz (Doom)]], could be a different character than [[Marine (Doom II)]], or even [[Marine Commander]] from Final Doom (it's not specific). Doom RPG website claims its the same marine in at least Doom, Doom 2 and Doom 3. While BFG Edition even claims that its the same guy in Doom, Doom 2, Doom 3, and Resurrection of Evil (despite clear explanation that its a different character in ROE in the original manual, and based on ID/backstory of the character in the game itself).

Quake Champions ties all the characters from Doom 1, Doom II, Doom 64, Doom 3,  Doom (2016)/Doom Eternal, and Quake Arena, as the same character. The Lost Missions ties Doom 64 into Doom 2016/Doom Eternal.  Quake Champions implies that the marine's very first adventure was in Doom 3 (making it a prequel to the rest of the series);

:Recently transferred to Mars, this soldier got more than he asked for when Dr. Betruger betrayed the UAC.

:PDA: Given to you on your first day on Mars. Allows you to read other people's email and hear their personal recordings.

Doom 64 apparently takes place after "Doom II" (and thus may make the events of Final Doom take place with different character, or characters "[[Marine Commander]]").

According to Doom 64 (2020):
:"Welcome, to DOOM 64! The cult classic returns, 22 years after its 64-bit debut. In this follow up to DOOM II, you'll fight through demonic hordes, hunt down the Mother of Demons, and stop Hell's invasion as you battle more than 30 action-packed levels!"

Important UAC personnel such the company's lawyer and counselor Elliot Swann and his bodyguard Jack Campbell, who arrived hours before the outbreak to make an assessment of the whole Mars operation and enact damage control if necessary, were found dead. Master Sergeant Thomas Kelly and other Delta Labs scientists were also found dead. The marine team had no information regarding the fate of Dr. Malcolm Betruger, the chief scientist of Delta Labs who - unknown to them - had become the demon Maledict.
**The [[Marine]] (apparently known as [[B.J. Blazkowicz (Doom RPG)]] who survived the attacks in November returns to Mars to investigate strange reports going on there.<ref>http://web.archive.org/web/20060104031037/http://www.doomrpg.com/n.x/Doom%20RPG/Home</ref> Research continues at another base, the [[Mars Outpost]].

**Doom II
***A Doom Marine (who had helped defend Mars Base from invasion) heads to Earth from UAC Mars Base in a drop pod and sees that the Demons have begun conquering Earth (Doom II manual).
***Doom Marine fights across earth, defeating demons, and working his way back into Hell again.
***Master Levels (Teeth) - The U.A.C. Marine is accidentally lost on Titan, the moon of Saturn.

**After Hell's catastrophic invasion of Earth, the United States took steps to try to prevent another invasion from occurring. The old UAC corporation was re-founded, though it survived most its top level management had destroyed. It was turned over to strict government supervision, under completely new management (Final Doom).
**The new government supervised UAC set up a new base on one of the moons of Jupiter ([[Io]]), as it continued its research into matter apportation and transportation under increased safety measures. They had hoped increased distance would enhance Earth's safety if something went wrong, and marines were stationed at the base, ready for anything (Final Doom: TNT: Evilution).
*'''2149'''
**The Invasion of the Jupiter moon base began not long after the opening of the first [[Gate]]. The United States Space Marine Corps were prepared and won the battle. Research continued but less cautiously...
**Several months later, believing that yearly supply ship was on its way, were caught in surprise as Demons attacked and invaded from space via flesh and metal mother ship. They were unprepared to fight an attack from above.
**The Marine, now the ''[[marine commander]]'' was the only survivor left, as he was miles away from the base taking a stroll on the moon's surface at the time. He heard the sound reminding him of the nightmares he still had (from his previous battles with the demons). He returned to the base to discover his men dead, and vowed to take revenge (TNT:Evilution).
**It began to research tools and technologies to prevent future invasions from happening again (The Plutonia Experiment). With Earth invasion stopped, the remaining demons were gradually exterminated by mopping-up squads. The new UAC began working on quantum Accelerator devices, intended to close interdimensional gates at a distance and prevent future incursions. Scientists began to work with Gate technology again in order to learn how to close the Gates. This drew attention from beings from [[Outside]]. A new Terror began as a Gate was opene dup in the research complex. But the scientists were ready and closed the gate with their [[Quantum Accelerator Device]], closing it instantly and permanently. The next day another invasion struck using seven Gates, while six of the gates were closed, the marines were not able to hold out, and everyone was killed.
**The Marine who had been put on leave on a beach near by the complex was called in by the government to fight back and recover the Quantem Accelator and destroy the Gatekeeper guarding the last [[Gate of Hell]]. Being the only Marine left with no backup for an hour or two, he had to stop the Demon's plans or it would be too late. He took on the horde, to stop the Gatekeeper, and prevent another demonic invasion of the world.
**The Marine's (B.J. Blazkowicz) fatigue was enormous, his price for encountering pure evil (no mortal was meant to experience hell). The military doctors submitted him tests and treatments, which were of little help. The night mares continued. In the end by planetary policy, all was classified and sealed. The installations were sealed, and abandoned, and absolute quarantine guaranteed by apocalyptic levels of radiation (Doom 64).
**October (Doom 2016) (parallel universe?, see below).
*'''Years Later'''
**Doom 64 - A relay satellite activates after years of bombarding by neutrons and sends a final message to Earth showing energy signatures unlike anything sampled before coming from the abandoned installations. The classified archives were opened it was discovered that a single entity with vast rejuvenation powers, masked by the extreme radiation levels, escaped detection. It systematically borught he decaying dead back to corrupted living tissue (into something stronge and more vicious than before).
**As the only experienced survivor, the tough Marine (B.J. Blazkowicz III)'s commission was reactivated and given the order for Mercilous Extermination. He returned to a space installation he once saved from demons, forced to kill the beasts again when they are resurrected, he travels back to their world (Hell) where he kills the [[Mother Demon]]. He decided to remain in hell to continue to battle the forces of hell to ensure that no demon arises again.
**Doom 64 Lost Levels begins. A new chapter in the Doomguy's saga, taking place shortly after [Doom 64's] original campaign concludes. The Mother Demon the marine defeated, had a sister, and Doomguy has been messing up Hell non-stop, she tried to get rid of him by sending him away.
**Doom 64 Lost Levels ends.

;Outside of Time and Space
*The [[Arena Eternal]] is an extradimensional structure created by the Vadrigar and populated with the greatest warriors in all of time and space. The Doom Marine, and other survivors of Phobos invasion: Crash, and Phobos were brought their from their eras to fight.
*According to Quake Champions; Ranger the character based on the player in Quake 1 has a photo from 1978, that is 30 years old. Placing Quake in 2008. The first Slipgate may or may not have sent him one hundred years into hte future, to 2108. He is also a Vietnam veteran.
*The Global Defense Force, or GDF, is a supranational paramilitary organization, formed in the mid-21st Century from a large pool of national military organizations and relief agencies, to combat increasingly severe weather events, other natural disasters and terrorist campaigns, as well as to keep the peace in historically unstable regions such as the Middle East. It was created shortly before the Strogg invasion of Earth.
The GDF is a fencible military, as opposed to the Space Marine Corps which is expeditionary.
*The Strogg invaded Earth in the mid-21st Century in search of biological components. The Strogg invaded the Earth in the middle of its 21st Century period, taking its inhabitants completely by surprise. Their large invasion fleet arrived in orbit over the world seemingly out of nowhere, and its ground forces quickly proved themselves a dire threat to the existence of Mankind. By the mid-21st century humanity is fighting for its survival against the hostile alien threat seeking to end the Strogg once and for all by invading their homeworld.
*How Quake fits into the shared universe is not clear, and there is little work done collecting the dates and timeline from that game and comparing it to Doom series (other than Quake 2/4 appears to take place during the mid 21st century, and majority of Doom takes place in the 22nd century), but could also take place in parallel universes that connect to each other. Doom III Arena's mentions that the Eternal Arena was built "millennia ago" and ties together Doom, Quake 1, and Quake 2 via several characters including Doom, Phobos, Crash, Ranger, Bitterman, Major Wayland, Tankjr, and Wrack.
*In addition there are smaller side and alternate timelines from the novels. Note: Bethesda's latest Wolfenstein reboot series The Old Blood and the The New Order which follows Nazis winning WW2 is set in its own timeline as well, but likely doesn't connect to any Doom iteration universe (at least as of yet there is no evidence of space Nazi influenced UAC in the newest game.
*Note: It appears that Doom Classic has to take place "after" Doom 3 in the "iD timeline" due to the fact that Doom 3 marine has the same backstory as classic Marine. Whereas placing it as a prequel set in the early 21st century would seemingly cause a number of issues (assuming time travel/time dilation/etc is not involved). Noting that Dafydd novels did in fact introduce extreme 'time dilation' (adding 500 years between Doom 2 and the final novel), and Doom 2016 definitely brings up time travel, but if set after Doom 64 would likely cause issues (if Doom 64 is set before Doom 3), unless Doom 64 took place after Doom 3. For it to be the same Marine would make that marine over a hundred years old (or least had to have jumped forward in time via time dilation during his travels). It would also have to assume he either assaulted an officer again, or that the new command decided to return him to Mars for officer he assaulted over a century before. Also Deimos still exists at the time of Doom RPG and there are other nods alluding to Doom Classic will occur later. Lastly, 2018-2022 classic timeline dates, predates the joint UAC/Military 2025 [[Mars Expeditions]] mentioned in Doom RPG website. Unless there was an even earlier expedition, and the 2025 date was a second expedition.
*[[Sam]] a droid that appears in Doom Resurrection, also appears in Doom RPG. His final outcome is confirmed in Doom RPG.
*B.J. Blazkowicz from the Germans won 'alternate universe' appears as a character in Quake Champions. The game looks to be a reimagining or sequel/remake of Quake III Arena and Quake Live, but no story details if any have been leaked. But is said to have its own lore<ref>http://www.penguinrandomhouse.com/books/564078/quake-champions-players-journal-by-prima-games/9780744018462</ref>, and is set across 'dimensions'.
