Doom 3 novels timeline

Background
The Doom 3 novels and Doom 3 game have very different dates for when the events of the story take place. The novels place the outbreaks earlier in the year during March 2145, where as it was November in the game. Other details throughout are very different than in the game as well (including number of individuals who landed on Dropship, the number of survivors, as well as characters who do not appear in the game, and the final outcome of the Marine). However it is notable that at least some of the original material from the novels had influence on Doom RPG's extended lore.

However, these novels are generally considered to be an alternate retelling of Doom 3, the story generally mirrors that of Doom 3 with some major differences in the characters stories.
