Deus Ex is a series of first person role-playing games originally produced by Ion Storm and published by Eidos Interactive. Eidos Interactive was bought by Square Enix in 2009, with Square Enix subsequently becoming the owner of the Deus Ex franchise. After the closure of Ion Storm, the task of reviving the franchise was given to the Eidos Montréal studio.
Being set in a dystopian near future, its story, universe, and artwork are heavily influenced by the cyberpunk genre. The series is inspired by films such as Blade Runner and RoboCop as well as numerous other cyberpunk works of fiction.
There are four full-length titles in the series: Deus Ex, Deus Ex: Invisible War, Deus Ex: Human Revolution and Deus Ex: Mankind Divided, which is the latest game of the series. A spin-off game Deus Ex: The Fall was originally released for iOS and Android mobile platforms and later ported to PC. There are also books set in the Deus Ex universe: Deus Ex: Icarus Effect, Deus Ex: Fallen Angel, and the Deus Ex: Human Revolution comics. In 2016 a tie-in novel Deus Ex: Black Light has been added to the series, as well as the mobile game Deus Ex GO.
The world of Deus Ex features a cyberpunk universe that draws heavily upon present day conspiracy theories. These include the Illuminati, Majestic 12, and Knights Templar conspiracy theories, as well as the existence of grays and the supposed secret research that takes place at Area 51. Whilst all Deus Ex titles have distinct settings and story lines, together they explore the methods used by the world's elite to control and manipulate society.
The world of Deus Ex does not significantly differ from the real world until the 20th century. Technologies that currently do not exist appear in the Deus Ex universe, such as human augmentations, Artificial Intelligence, and transgenics. Most of the games takes place in fictionalized versions of real-world locations, including New York City, Cairo, Detroit, and Prague.
