Deus Ex

Deus Ex is a classic video game, maybe one of the most famous. Released in 2000, this Action-RPG game combines multiple gameplays (FPS, Stealth, Role playing elements, immersive sim), 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.

Deus Ex is set in 2052, in a dystopian cyberpunk future beset by terrorist acts, economic inequality, and a plague dubbed the Gray Death. You play as JC Denton, 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.
