Deus Ex: Human Revolution is an action role-playing game developed by Eidos Montréal and published by Square Enix's European subsidiary in August 2011 for Windows, PlayStation 3, and Xbox 360. A version for OS X was released the following year. It is the third game in the Deus Ex series, and a prequel to the original Deus Ex (2000). The gameplay—combining first-person shooter, stealth, and role-playing elements—features exploration and combat in environments connected to multiple city-based hubs, in addition to quests that grant experience and allow customization of the main character's abilities with items called Praxis Kits. Conversations between characters feature a variety of responses, with options in conversations and at crucial story points affecting how some events play out.
