Deus Ex ([ˈde.ʊs ɛks]) is a series of action role-playing first-person shooter stealth video games. The series was developed by Ion Storm for the first two games and Eidos Montréal for later entries in the series. The series, set during the 21st century, focuses on the conflict between secretive factions who wish to control the world by proxy, and the effects of transhumanistic attitudes and technologies in a dystopian future setting.

The series currently consists of six games: Deus Ex (2000), Deus Ex: Invisible War (2003), Deus Ex: Human Revolution (2011), Deus Ex: The Fall (2013), Deus Ex Go (2016) and Deus Ex: Mankind Divided (2016).

Eidos stated in October 2013 that future entries in the series would go under the umbrella name Deus Ex Universe. The series has received much critical acclaim over the years, and sold over 4.5 million units worldwide.

Note: given the freedom of choice found within each game, the section below only gives the general outline of the world and the individual plotlines.

While each game has a distinct story, they are all set within the same world: an Earth of the future which has evolved a dystopian, cyberpunk society. In this setting, several organizations compete for overall control of the world. Several of the societies mentioned or shown are inspired by real-world and invented secret societies and conspiracy theories. The one constant through the series is the Illuminati, although FEMA, Majestic 12, and the Knights Templar are also featured. The main characters in the series possess artificially acquired superhuman abilities, generally referred to as "Augmentation", and more specifically called "Human augmentation" in the third game.
