Gameplay
Deus Ex incorporates elements from four video game genres: role-playing, first-person shooter, adventure, and "immersive simulation", the last of which being a game where "nothing reminds you that you're just playing a game". For example, the game uses a first-person camera during gameplay and includes exploration and character interaction as primary features.
The player assumes the role of JC Denton, a nanotech-augmented operative of the United Nations Anti-Terrorist Coalition (UNATCO). This nanotechnology is a central gameplay mechanism, and allows players to perform superhuman feats.
