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).

Quake series

 * The Arena Eternal is an extradimensional structure created by the Vadrigar and populated with the greatest warriors in all of time and space. The Doom Marine, and other survivors of Phobos invasion: Crash, and Phobos were brought there from their eras to fight.
 * Ranger is brought in from his own era to fight as well.
 * 21st Century - The Global Defense Force, or GDF, is a supranational paramilitary organization, formed in the mid-21st Century from a large pool of national military organizations and relief agencies, to combat increasingly severe weather events, other natural disasters and terrorist campaigns, as well as to keep the peace in historically unstable regions such as the Middle East. It was created shortly before the Strogg invasion of Earth. The GDF is a fencible military, as opposed to the Space Marine Corps which is expeditionary.
 * The Strogg invaded Earth in the mid-21st Century in search of biological components. The Strogg invaded the Earth in the middle of its 21st Century period, taking its inhabitants completely by surprise. Their large invasion fleet arrived in orbit over the world seemingly out of nowhere, and its ground forces quickly proved themselves a dire threat to the existence of Mankind. By the mid-21st century humanity is fighting for its survival against the hostile alien threat seeking to end the Strogg once and for all by invading their homeworld.
 * Doom 3 references to Quake: Quake-43, Quakecon Games and Hunter (character).
 * The "Armstrong" was an Orbital Space Station in low orbit around the Earth. During the Strogg invasion of Earth, it was used by the U.A.C. to study and store creatures and weapons developed on Mars. When the Strogg invaded Earth, the station had been turned into an Orbital Defense Platform, but it was ultimately taken down by the Strogg. During this incident, Kane found an old U.A.C. weapon which he used to survive. He turned out to be the only survivor of this attack, but United Nations kept him quiet about this incident, leading to rumors that the weapon wasn't all he had found.
 * Doom imagery appears in Quake III Arena. The image of a Lost Soul on the lower side of Anarki's board. Another typical Doom image (Demonic head in a pentagram) can be seen on the back of Biker's jacket. There are also several images of the Icon of Sin appearing as wall decorations on some of the maps.
 * BFG 10K (the next model after BFG 9K) appears in Quake II and Quake II Arena.

Doom Bible
(Includes all events described or mentioned in the Doom Bible document by Tom Hall) The Doom Bible may of be some interest to individuals looking into the history of Doom's development. While the unused storyline doesn't have any dates to make a specific timeline (other than characters ages) there is at least a detailed list of events.
