Something worth checking out for fans of the series who may not already be aware of it: The Deus Ex Bible. It may not be entirely relevant to the series as it is today, but it’s interesting nonetheless. I’m sure the people currently responsible for the continuation of the Deus Ex universe have read the original design docs or at least independently gathered what information is publicly available from various sources to draw from to some extent.
This document is intended to summarize the key backstory information behind the Deus Ex universe. It is comprised mostly of excerpts from the design documents of Deus Ex 1, with a few additions and modifications for the sake of maintaining consistency with the final game. The hope is that the amount of information will be helpful without being overwhelming.
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.
This document was also used for the foundation of Deus Ex: The Conspiracy for the PS2, and will probably be used in some fashion forDeus Ex 2 to maintain continuity.
