Deus Ex is a first-person action role-playing game developed by Ion Storm Austin and published by Eidos Interactive for Windows in 2000. It blends first-person shooting, stealth, hacking, and role-playing mechanics in a cyberpunk conspiracy setting. Players control JC Denton, a nano-augmented agent for the United Nations Anti-Terrorist Coalition (UNATCO), as he investigates a global plague and uncovers a web of competing shadow organizations. The game is known for its open-ended level design that lets players approach objectives with combat, stealth, hacking, or social manipulation, and for its deep skill and augmentation system that allows extensive character customization. The real-time combat and exploration are built on a modified Unreal Tournament engine, supporting interactivity with a wide range of everyday objects. Deus Ex received critical acclaim for its emergent gameplay and player choice, winning multiple Game of the Year awards, and it established a franchise that includes sequels, prequels, and a 2011 Human Revolution revival. Its narrative, which delves into themes of transhumanism, surveillance, and political control, is often cited as one of the most ambitious in video games.
