''Deus Ex'' is an [[action role-playing game]] with incorporated [[first-person shooter]] and [[Stealth game|stealth]] mechanics. Players take on the role of [[JC Denton]], a man equipped with nanotechnology-based cybernetic enhancements called augmentations.<ref name="IGNpreview"/><ref name="PCZpreview"/> At the game's opening the player chooses a combat [[Difficulty level|difficulty]]−"Easy", "Medium", "Hard", or "Realistic"−and customize Denton's real name, visual appearance, and starting skills.<ref name="Manual"/>{{Rp|2–4}} The player moves around the environment, being able to climb ladders and jump onto crates, swim through bodies of water, and crouch to negotiate narrow spaces. The environment also has interactable objects such as computers and keypads, and certain objects in the game can be carried or thrown, from small items like boxes to human bodies.<ref name="IGNpreview"/><ref name="Manual"/>{{Rp|9–11}}<ref name="gamespot"/>

Each hub area of the game has a variety of missions given to the player by [[non-playable character]]s (NPCs), which the player can choose to accept or ignore; these missions include [[Quest (video games)|quests]] linked to the main story and side quests unique to each hub area. These objectives can be completed in a variety of ways; these include using stealth to infiltrate an area, opening access points using hacking, launching an armed assault, or a combination of different tactics.<ref name="IGNpreview"/><ref name="PCZpreview"/> When talking with NPCs, the player has access to multiple dialogue options, with the option chosen influencing the course of the conversation. Short messages are also given which direct the player towards different objectives.<ref name="Manual"/>{{Rp|13}}

There are a variety of melee and ranged weapons in the game, both lethal and non-lethal; ranged weapons can be upgraded using kits found during gameplay. Items, weapons, ammunition, and equipment can be purchased with credits, the in-game currency either gathered in the environment or earned through quests, or found during exploration. [[Item (game terminology)|Items]] that can be picked up include weapon ammunition, [[Health (game terminology)|health]] restoratives, and tools for bypassing barriers; lockpicks for mechanical locks, and multitools for electronic devices. The player's heath is divided between multiple body parts, each requiring healing with items or at healing stations.<ref name="IGNpreview"/><ref name="Manual"/>{{Rp|9–12}}<ref name="gamespot"/> Inventory space is limited, with items and weapons taking up varying amounts of space.<ref name="IGNpreview"/>

Denton's abilities can be enhanced over the course of the game. [[Experience point|Skill points]] earned by completing quests can be spent on the eleven skill types; computers, electronics, the environment, lockpicking, medicine, swimming and five weapon proficiencies. For instance, raising environment proficiency allows for higher jumps and more resistance to hostile environmental effects.<ref name="IGNpreview"/><ref name="EuroPreview"/> During [[character creation]] skill points can be reassigned from one skill to another, but after this point skill increases are permanent.<ref name="Manual"/>{{Rp|2–4}} Additionally, augmentation canisters can be found or bought throughout the game. Denton starts with three augmentations; the story-based infolink communicator, a light, and a tool for identifying hostiles. Other augmentations, such as increased movement speed, can be unlocked and upgraded using canisters a maximum of four times. One body area can only have one augmentation installed, and they are permanent. Using an augmentation costs energy, which is restored using consumable biocells.<ref name="IGNpreview"/><ref name="Manual"/>{{Rp|7–8}}<ref name="EuroPreview"/>

A post-release patch added a [[multiplayer]] option. Set across different large [[Level (video games)|levels]] pulled from different areas of the game, multiplayer was limited to "[[Deathmatch (video games)|deathmatch]] and "team deathmatch" modes, where players fought to the death either individually or as allied groups. [[Spawn point]]s provided players with tools and equipment to navigate the level and fight other players, although there were a stricter inventory limit. Unless specified by the match host, players only receive augmentation canisters based on their kills, and must still between different upgrades.<ref name="Multiplayer"/> The multiplayer mode's servers shut down in April 2014.<ref name="MultiShutdownA"/><ref name="MultiShutdownB"/>
