Console Doom timeline

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 obvious reasons the Doom RPG Timeline, Doom 3, and 2016 Doom timelines are considered seperate canons, and No Rest For The Living is regarded as non-canon entirely.

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 is the descendent of the main characters from Wolfenstein and Commander Keen series. He is the son of Commander Keen. Tom Hall's comments that he is the son of Commander Keen, this supports the theory that the timeline of the SNES manual is still valid. Since Keen grew up in the late 1980s-early 90s and likely would have had a son in the early 21st century.
