Doom Wiki


There is some indication that Doom RPG is tied to Doom, Doom II, and Doom 3, according to the Doom RPG's old website (see Doom Retcon Timeline), placing the series in the 22nd century.

While there are connections between Doom II RPG and Doom Resurrection (iPhone) (see Garrett and Sam), and thus loosely connected to Doom 3, this timeline is mostly concerned with the dates given in Doom RPG/Wolfenstein RPG materials.

Doom RPG Timeline[]

(Doom RPG, Doom RPG II, Doom II RPG Comic, Wolfenstein RPG, UAC Website[1])

Note: Doom RPG only has a few given dates most of them are taken or based on dates from Doom 3 including a tie in UAC website made for it and inspired by Doom 3 Novels (the website also introduces more information about Doom 3 related characters such as Ian Kelliher and his father both from the novels). 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). In addition there are some tie-in connections between Doom II RPG and Doom Resurrection (another Doom 3 spinoff game), but the date for that game can be found in the Doom 3 section. Furthermore the Doom RPG website seems to indicate that Doom 1-3 also appears in this timeline as well, and the first Doom RPG shares the same character. There is also some crossover between Lost Mission and Doom RPG II. While exact order of Doom 1-3 are not known exactly, it does appear that classic doom was likely retconned to having taken place in 22nd century (rather than 21st as it was in Doom SNES), possibly making Doom 3 (prequel to Doom 1/2).

  2. A question asked, and the code to a door in Doom RPG. See also David Whitlark's communications.
  3. David Whitlark discovers a copy of Doom, and doesn't get his work done by Tuesday. He says that it must be at least 100 years old. He is surprised that the setting and scenario is similar to their own. He finds it funny. He also mentions they are making Doom for the cell phone. Considering that Doom II RPG takes place in 2145, David is probably off by about 50 years in his dating.
