The Doom Timeline is the structured events of the original series of Doom games from the original 1993 release to the 1997 Doom 64. For a more complete listing of the timeline from iD multiverse perspective see ID multiverse timeline.[1]

Background

DoomMNLIndex

Noteably, Doom (and the early sequels) does not have clear dates for when events take place. It is implied to take place during early 21st century in a neo-1990s retrofuturistic setting, and there are only a few references to amount of time between games. Only the SNES manual gives any 'clear dates' for the events leading upto the events of the original Doom. Otherwise there really isn't much of a timeline to actually list.

Tom Hall has indicated that the protagonist of Doom (the original Doom/Ultimate Doom which he worked on) is the descendent of the main characters from Wolfenstein and Commander Keen series. He is the son or grandson of Commander Keen (which was part of the early concepts of the ID multiverse).[2][3] Tom Hall's comments that he is the son of Commander Keen, this supports the theory that the timeline of the SNES manual is accurate. Since Keen grew up in the late 1980s-early 90s and likely would have had a son in the early 21st century. The Doom RPG series also took this route with the characters B.J. Blazkowicz III and Stan Blazkowicz (though clearly from a later century). The novels which lie outside of the game canon (or canons) also places the general events in the early to mid 21st century, see Doom novels timeline.

Certain aspects about classic Doom games and their manuals are confusing and don’t always seem to line up. This has opened up theories that there are events not covered in the game’s or even multiple Doom Marines involved. For example Doom’s original ending and Ultimate Doom’s ending are different than the prologue to Doom 2 with the heroes reaching Earth by different means. Doom 2 also talks about Mars Base being invaded as well from the Outside, and the invasion stopped by the marine who lands on earth via drop ship discovering that Earth has been invaded. Some fans think this might even be the events shown in Doom 3.

Several of the later manuals and websites claim it’s the same hero in all the games confusing matters further.

Note: Technically no exact date is given for Doom II, but its assumed by the fans to take place directly after Doom/Ultimate Doom at least chronologically.

Notes

DoomManualPG23
  • According to the SNES manual; "When the Creatures first appeared in at the Gateways, their images were captured by remote video cameras. The video Data was computer analyzed by the UAC and the results are provided here, AND ONLY HERE, to help you determine what you're up against. Some call them Demons, some Call them Monsters. Whatever they are, the're not of this world and they're waiting for you."[12]
  • Further more each of the enemy recognition screen data listings includes "Time" when they were first appeared in the cameras.
Former Soldiers were first appeared at 17:48. Former Sergeants first appeared at 03:21, Imps appeared at 11:34, first images of Demons was at 20:17, Lost Souls at 02:47, Cacodemons at 09:35, Barons of Hell at 22:59, Cyberdemon at 13:26, Spider Demon at 11:11. The times are there for flavor and show that they they all appeared on the same date, though the times are not particularly useful information beyond that.
  • Another miner change which might change certain contexts is that the SNES manual changes the description related to artifacts from 'the other dimension' to 'the other dimensions' plural for whatever reason, perhaps suggesting that Hell takes place in multiple dimensions or that UAC has accessed multiple dimensions (in Doom (2016) the possibilities of multiple dimensions is discussed see Worlds and Time).
  • According to the Doom 64 manual it mentions “planetary” twice and both “space installation” (space installations) when discussing previous events. Some believe this may be a reference to the Mars Base invasion on Mars rather than Phobos/Deimos invasions which occurred on the moons (rather than planets).
  • Technically no date for Doom II's events are ever given in any source (other than mid-21st century in the novels). The novel is a very loose adaptation practically a different/original story even, lacking most of locations and events from Doom II. Though characters do reach earth from Deimos using a shuttle, which might be loosely inspired by the drop pod account in Doom II manual.
  • In Doom RPG Deimos is missing, which appears to be a nod to Doom/Ultimate Doom (and a hint that at least in the ID multiverse it takes place after Doom, and is in the same timeline as hinted on the website). Though it takes place in the 22nd century.
  • The official doom strategy guide mentions 2500 B.C. as the date of Sun Tzu.
  • The official Doom II strategy guide ignores much of the first part of the intro to Doom II instead retelling the events at the end of original Doom (but minus the events of Thy Flesh Consumed): "At the end of DOOM, Our Hero, having returned to Earth, is left staring at a flaming city, evidence that the demon aggressors have arrived ahead of him.[13]
