Deus Ex Wiki

The DX1 Continuity Bible,[1] commonly known as the Deus Ex Bible or the Deus Ex Continuity Bible, is a collection of content from design documents for Deus Ex, along with Q&A sessions between developers and editors at Planet Deus Ex and GameSpy. The Deus Ex Bible was published on GameSpy in April 2002, and includes backstory content for the Deus Ex universe along with developer commentary.


The Deus Ex Bible was intended to summarize key backstory information behind the Deus Ex universe, with a few additions and modifications for the sake of maintaining consistency with the finished game. For example, the Deus Ex Bible includes details expanding on the backstory of JC Denton and Paul Denton.

The Deus Ex Bible also includes story-related elements that existed during development but are unmentioned in the final game, such as the location of Mount Weather (the site where Daedalus was created) and the Russo-Mexican alliance (a military faction at war with the United States). In reference to the presence of cut content, the editor's note states that the backstory pieces in the Deus Ex Bible should be considered to be canon "whenever possible but not necessarily with religious fervor":

Be aware that much of the backstory detailed below never made it into the final game. Some of the events described were intended to be missions (Texas, the space station, moon base, Mt. Weather; etc.), and a lot of that content either doesn't appear in Deus Ex or does so in glancing, fragmentary ways.

What that means is that the related pieces of backstory should be considered truthful and should be supported whenever possible but not necessarily with religious fervor. It would be perfectly valid to re-imagine what's really going on at the "moon base," for instance.

— Editor's note in the Deus Ex Bible

The Deus Ex Bible served as a basis for the later games developed by Eidos Montréal. According to Mary DeMarle, narrative director of Deus Ex: Human Revolution, the world depicted in Human Revolution was created by filling in the blanks in the timeline described in the Deus Ex Bible:[2]

Not only have we heard about the Deus Ex bible, it was also required reading before we began work on the story concept for Human Revolution. After reading it, we spent several months filling in some of the blanks in its timeline and history in order to create the characters, companies, cities, and world events that exist in 2027.
