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

Classic Doom (Original Doom Games):

(Includes Ultimate Doom, Doom II, No Rest for the Living, Final Doom, and Lastly Doom 64.)

Note: Doom does not have clear dates for when events take place. It is implied to take place during early 21st century in a couple of early sources (tie-in novels and SNES manual, and possibly a few other sources), and there are only a few references to amount of time between games. Only the SNES manual gives a 'clear dates' for the start of Doom 1. Otherwise there really isn't much of a timeline to actually list.

  • 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.[1]
  • 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.[2]
  • 2022[3]
    • March 15 - Mars receives a message from Phobos base stating that the base under attack and requesting backup.[4]
    • 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
    • No Rest for the Living begins.
    • Plutonia Experiment begins.
  • 2023 (or at least a year after Plutonia Experiment[5])
    • TNT:Evilution begins.
    • The fatigued marine is decommissioned, and the military DOOM Episodes are classified. The UAC's bases are sealed, and quarantined by radioactive bombardment.
  • Years Later[6]
    • Doom 64 begins. Doom Marine is re-commissioned to stop a new threat, from a deepspace installation he once fought the Demons at.

Doom RPG

(Doom RPG, Doom RPG II, Doom II RPG Comic, Wolfenstein RPG, UAC Website[10])

The exact date for when Doom RPG begins is not given, but appears to be set in late 2145 (the UAC website itself is under 'lockdown' from the events from the games Doom RPG/Doom 3).

Other material

Doom 3 novels:

Note: The Doom 3 novels and Doom 3 game have very different dates for when the events of the story take place. The novels place the outbreaks earlier in the year during March 2145, where as it was November in the game. Other details throughout are very different than in the game as well (including number of individuals who landed on Dropship, the number of survivors, as well as characters who do not appear in the game, and the final outcome of the Marine). However it is notable that at least some of the original material from the novels had influence on Doom RPG's extended lore (some of that information can be seen in its own section above).

  • 2-1,000,000 B.C.[34] Ancient Martian civilization is built.
  • 400,000 B.C. - Height of the Martian civilization.[35]

Doom novels timeline

Quake series

  • 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 there from their eras to fight.
  • Ranger is brought in from his own era to fight as well.
  • 21st Century-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.
  • Doom 3 references to Quake: Quake-43, Quakecon Games and Hunter (character).
  • The "Armstrong" was an Orbital Space Station in low orbit around the Earth. During the Strogg invasion of Earth, it was used by the U.A.C. to study and store creatures and weapons developed on Mars. When the Strogg invaded Earth, the station had been turned into an Orbital Defense Platform, but it was ultimately taken down by the Strogg. During this incident, Kane found an old U.A.C. weapon which he used to survive. He turned out to be the only survivor of this attack, but United Nations kept him quiet about this incident, leading to rumors that the weapon wasn't all he had found.
  • Doom imagery appears in Quake III Arena. The image of a Lost Soul on the lower side of Anarki's board. Another typical Doom image (Demonic head in a pentagram) can be seen on the back of Biker's jacket. There are also several images of the Icon of Sin appearing as wall decorations on some of the maps.
  • BFG 10K (the next model after BFG 9K) appears in Quake II and Quake II Arena.

Doom Bible

(Includes all events described or mentioned in the Doom Bible document by Tom Hall) The Doom Bible may of be some interest to individuals looking into the history of Doom's development. While the unused storyline doesn't have any dates to make a specific timeline (other than characters ages) there is at least a detailed list of events.


  • Originally 'Classic Doom' was apparently seen as taking place in the 21st century (as also 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 22nd century (2140s).
  • Sam is a character who appears in Doom Resurrection and Doom II RPG. His final outcome is confirmed in Doom II RPG.
  • Garret from Doom Resurrection is also mentioned in Doom II RPG.
  • On the Doom RPG: "Doom RPG is a first-person turn-based role playing game set in the Doom reprise the role of the Doom Marine made famous in the groundbreaking id Software titles Doom, Doom II, and Doom 3. Say goodbye to humdrum mobile gaming and prepare yourself for the return to Mars in a showdown with the legions of Hell!"
  • On Doom 2016 (at least initially it was not a 'reboot' but it has undergone at least three revisions (the second was very different[53]) so is unclear how much of first revision 'survived'): "It's not a sequel to Doom 3, but it's not a reboot either. Doom 3 was sort of a reboot," Hollenshead told Gamestop. "It's a little bit different than those, and if I told you why, I would get my ass kicked when I got back. So I'll just have to leave it at that."[54]
  • The introduction in the Doom 3 BFG Edition manual implies that the characters from several games are the same individual, and they represent his adventures: "Step into the boots of DOOM Marine and experience his adventures for the first time, or all over again.  Featuring enhanced versions of DOOM 3, DOOM 3: Resurrection of Evil and the all new DOOM 3: The Lost Mission, plus the classics DOOM and DOOM II, DOOM 3 BFG Edition is the consummate DOOM experience. Interestingly this seems to go as far to suggest that the marine in Resurrection of Evil is the same marine as Doom 3 (which if true would have to suggest that Marine combat engineer actually did know the nature of the previous incident despite what the manual suggests). However, it also seems to imply that the Bravo Marine in Lost Mission is the same marine, but this is impossible as its timing overlaps with events of Doom 3 (only 6 hours into the invasion).
  • The Soul Cube appears in Doom (2016) a reference to Doom 3.
