Console Doom timeline

This article contains the various timelines created by various developers of Doom games. Including iD software, Midway, and Bethesda software and others.

Background
Originally 'Classic Doom' was apparently seen as taking place in the 21st century (as seen in Dafydd novels, and SNES Doom manual). Doom 3  (and Doom 2016) created a new timeline setting the events of that game in the 2140s.

However, according to later Doom RPG website and related UAC website Doom RPG took place in the same timeline and universe as Doom 1-3 (with Doom 3 apparently being a prequel to Doom I-II and Final Doom) each following the same Doom Marine character, according to the game the descendent of B.J. Blazcowicz who shared his ancestors name, and from those games tied into many other ID series including early Wolfenstein 3D up to Return to Castle Wolfenstein and Wolfenstein (2009). This can all be considered the ID Timeline.

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 infact influce 'time dilation' (adding about a century between end of Doom 2 and the final novel), and Doom 2016 definitely brings up time travel, but if set after Doom 64 would likey 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. 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.

It is still unclear if Doom (2016) is complete reboot or tied into this timeline or creates yet another alternate timeline, perhaps streamlined to include and build off of at least the events of Doom 3 as it includes shared dates and certain links to the previous game.

The Quake series may also be tied into this timeline via Quake III Arena but as of yet there is very little work done collecting the dates and timeline from that game and comparing it to Doom series. Doom III Arena's Eternal Arena built "millennia ago" tied together Doom, Quake 1, and Quake 2 via several characters including Doom, Phobos, Crash, 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.

Lastly its not clear if the Doom Movie is or was intended to take part in the Doom 3 or related timelines or not. It gives additional dates that might be of issue, and is set in 2026-2046 period.

Classic Doom Timeline
This is a timeline based on the dates given in DOOMNL Instruction Booklet from Doom SNES version. This was superseded by the ID timeline below (but may fit into the Dafydd timeline further below).
 * 2018 - The military, UAC's biggest supplier, has used the remote facilities on Phobos and Deimos to conduct various secret projects, including research on inter-dimensional space travel.
 * 2019- The Marine assaults a superior officer, and is transferred to Mars, home of the Union Aerospace Corporation.
 * 2021 - July 1 - DOOMNL 01-D19305-1C is published.
 * 2022
 * March 15 - Mars receives a message from Phobos base stating that the base under attack and requesting backup.
 * A few hours later, the marines land and try to stop the invasion. The Marine is ordered to stay behind and protect the perimeter. The marine forces are wiped out or turned into monsters. Planetary authorities send the final Marine the new DOOMNL 01-D19505-1D replacing earlier manual (now including briefing for the Marine, and 'images from the invasion captured by remote video cameras. The video data was computer analyzed by the UAC and the results are provided "here and only here"). The Marine leaves the escape pod vowing to destroy the invasion force.
 * Doom Begins
 * Doom II Begins
 * Plutonia Experiment begins.
 * 2023 (or at least a year after Plutonia Experiment)
 * TNT:Evolution begins.
 * The fatigued marine is decommissioned, and the military DOOM Episodes are are classified. The UAC's bases are sealed, and quarantined by radioactive bombardment.
 * Years Later
 * Doom 64 begins. Doom Marine is re-commissioned to stop a new threat, from a deepspace installation he once fought the Demons at.

 * Master Levels (Teeth) - The U.A.C. Marine is accidentally lost on Titan, the moon of Saturn.
 * No Rest For the Living - The Doom Marine stops another invasion by traveling to a Hell pocket universe to destroy another Cyberdemon from amassing an army.
 * 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).
 * 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 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).
 * 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) (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.


 * 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.

Doom 2016
Note: it is unclear if Doom 2016 is intended to tie into earlier Dooms or is simply a reboot of the series. Either case it may have an alternate timeline (streamlined from the ID timeline with different set of events) that may continue or expand off of the events of at least Doom 3, though some references seem to link to the events of Doom 64 (there are also some nods to classic Doom and Doom II imagery, including the scriptures showing him to be wearing the classic Marine Armor that the Marine wore in previous games). If the latter is the case it appear to diverge from when original Doom trilogy: Doom, Doom II and Final Doom take place in regards to Doom 3 & Doom RPG's (as Doom 2016 information seems to overlap the 2148 period), short of time travel.

On the other hand Doom 2016 takes place in 2149 (roughly around the time of or before TNT:Evilution, which takes place at least one year after Doom II/No Rest For the Living and Plutonia Experiment), and Doom Marine is described as having travelled through "Worlds and Time" (a reference to time travel) which might explain him 'disappearing' at the end of Doom 64, having his body discovered in 2145 only be resuscitated in 2149 without anyone realizing his identity for whatever reason, and just assuming him to be some kind of ancient warrior. Note, due to the placement of Doom 64 being years after original series (Doom to Final Doom) this would lead to Doom Marine more or less existing in two places at the same time both as retired Doom Marine (decommissioned after events of the original "Doom Military Episodes"), as well as the recovered Doom Marine from the Sarcophagus.
