Console Doom timeline

The Doom Timeline (SNES Doom Timeline) is the structured events of the original series of Doom games from the original 1993 release to the 1997 Doom 64, to 2020's Lost Levels. For a more complete listing of the timeline from iD multiverse perspective see ID multiverse timeline (Doom 3 as sequel).

Background
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). 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.
