Console Doom timeline

Classic Doom (Original Doom Games)
(Includes Ultimate Doom, Doom II, No Rest for the Living, Final Doom, and 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.

 * March 15 - Mars receives a message from Phobos base stating that the base is 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.
