Deus Ex is a series of first person role-playing games and related media. Since 2013, the name Deus Ex Universe has been used to refer to the interconnected games and print media in the franchise
The first two games were 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.  In 2022, the Deus Ex franchise, along with Eidos Montréal, was acquired by Embracer Group AB.
Set in a dystopian near future, the universe, stories, and artwork of the series are heavily influenced by the cyberpunk genre. The series is inspired by films such as Blade Runner, Escape from New York and RoboCop as well as numerous other cyberpunk works of fiction.
There are four full-length game 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 and comics set in the Deus Ex series, including: 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 was added to the series, as well as the mobile game Deus Ex GO and the comic series Deus Ex Universe: Children's Crusade which serves as a prequel to the events of Mankind Divided.
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. The Deus Ex universe features advanced technologies, 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.
