Press 1 for the first games

Deus Ex was the first game in the franchise and largely created most of the worldbuilding already present, with following games expanding on it.

In the dystopian near future, a deadly plague known as the Gray **** has befallen mankind. The only known "vaccine", Ambrosia, the distribution of which is tightly controlled by Orwellian government agencies, merely delays the inevitable. Terrorist groups are capitalizing on the increasing desperation of the common folk, and their increasing activity urges world governments to create the United Nations Anti-Terrorist Coalition (UNATCO). You follow JC Denton, a rookie elite UNATCO operative, who eventually becomes tangled in a conspiracy plot involving The Illuminati, The Knights Templar, Chupacabras, Greys, black helicopters, genetic design underground labs and rogue AIs.
