Deus Ex

Deus Ex is a 2000 action role-playing game developed by Ion Storm and published by Eidos Interactive. Originally released for Microsoft Windows, it was released for Mac OS the same year, and for PlayStation 2 in 2002. A remaster for modern platforms was originally scheduled for release in February 2026, but was later delayed to an unspecified date. The gameplay—combining first-person shooter, stealth, and role-playing elements—features exploration and combat in environments connected to multiple city-based levels, with quests that can be completed in a number of ways and character customization based around cybernetic enhancements. Conversations between characters feature a variety of responses, with choices at key story points affecting how some events play out. A post-release patch incorporated deathmatch-style multiplayer.

Deus Ex is set in 2052, in a dystopian cyberpunk future beset by terrorist acts, economic inequality, and a plague dubbed the Gray Death. The player character, the cybernetically enhanced JC Denton, is an anti-terrorism agent who is deployed when a terrorist group interrupts supplies of a rare Gray Death vaccine. Investigating the incident, Denton ends up involved in a struggle between multiple factions for control of the world. The story is inspired by popular conspiracy theory motifs, incorporating groups including the Illuminati and Majestic 12.
