It is fifteen years since the end of the global conspiracy depicted in Deus Ex - widely regarded as one of the greatest action games of all time. In the aftermath, a catastrophic depression has crippled the world and conflicting militant groups seek to enforce their own violently destructive agendas.

But in the huge, free-roaming world of Deus Ex it seems that the challenge is to know your real enemies. And for this you must uncover the veil of secrecy surrounding your own existence.
