'''''Deus Ex''''' is a 2000 [[action role-playing game]] developed by [[Ion Storm]] and published by [[Eidos Interactive]]. Originally released for [[Windows|Microsoft Windows]], it was released for [[Classic Mac OS|Mac OS]] the same year, and for [[PlayStation 2]] in 2002. The gameplay—combining [[first-person shooter]], [[Stealth game|stealth]], and [[Role-playing video game|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 in popular culture|Illuminati]] and [[Majestic 12]].

The game was created by [[Warren Spector]], who acted as director and producer, and put together a design concept during the early 1990s under the title "Troubleshooter". After being approached by Ion Storm about creating a project with complete creative freedom, Spector began pre-production in 1997. Staff included lead designer [[Harvey Smith (game designer)|Harvey Smith]], lead writer Sheldon Pacotti, and lead composer [[Alexander Brandon]]. The game was build using the [[Unreal Engine 1|Unreal Engine]], which led to issues with coding and NPC behavior. Due to technical and time limitations, some planned features and areas had to be downscaled or cut entirely.

Upon release, ''Deus Ex'' was a commercial success, selling one million copies worldwide. It saw critical acclaim from game journalists for its design and freedom of player choice. Its graphics and audio saw more mixed reactions. The PlayStation 2 port saw mixed reactions, but many praised its translation of the game's mechanics to console. It won multiple gaming awards, has been ranked among [[List of video games considered the best|the best video games of all time]], and fostered an active fan community. It was also been cited a prominent example of the "[[immersive sim]]". ''Deus Ex'' was expanded into a [[Deus Ex|series of the same name]], with a direct sequel ''[[Deus Ex: Invisible War|Invisible War]]'' releasing in 2003.

== Gameplay ==
[[File:How to pass obstacles in Deus Ex.jpg|thumb|left|Players are given multiple ways to traverse obstacles, from lockpicking to armed combat.]]
''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"/>

== Synopsis ==
{{Deus Ex Timeline}}

=== Setting and characters ===
''Deus Ex'' takes place in the year 2052 in a dystopian [[cyberpunk]] future on the brink of social and economic collapse, where multiple [[conspiracy theories]] and organizations are real.<ref name="DXbible1"/><ref name="RPSretro"/> The two main factions in-game are the [[Illuminati in popular culture|Illuminati]], portrayed as an ancient secret society controlling civilization from the shadows, and [[Majestic 12]], once subordinate to the Illuminati and now a splinter group. During the events of ''Deus Ex'', the world is being ravaged by a plague dubbed the Gray Death, with supplies of its Ambrosia vaccine limited.<ref name="DXbible1"/> The game takes place across multiple locations including multiple parts of the [[United States]] ([[New York City]], [[California]], [[Nevada]]), [[Hong Kong]], and [[Paris]]. A recurring location is [[Liberty Island]], which houses an operating base for the United Nations Anti-Terrorist Coalition (UNATCO). UNATCO's main conflict is with the National Secessionist Force (NSF), a terrorist group targeting Ambrosia shipments.<ref name="DXbible1"/><ref name="DeusexLocations"/> Another feature of the world is "augmentations", artificial enhancements using mechanics and nanotechnology.<ref name="DXbible1"/>

The main protagonist is JC Denton, an agent for UNATCO who has received advanced nanotechnology; he works at UNATCO with his brother Paul Denton, who shares the same nanotech augmentations, under the command of Joseph Manderley. Other important characters are Tracer Tong, a hacker allied with the Triads of Hong Kong; Morgan Everett, a high-ranking Illuminati member; Daedelus, an artificial intelligence construct and its successor Icarus; Walton Simons, newly appointed Director of the [[Federal Emergency Management Agency]] (FEMA); and Bob Page, a corporate CEO and current leader of Majestic 12.<ref name="UNATCOcharacters"/><ref name="DEIWguide"/>

=== Plot ===
''Note: While the general plot of Deus Ex follows a distinct path, many elements are subject to the player's decisions. The game also offers subplots that the player may or may not encounter, depending on their actions within the game. This synopsis concentrates on the main, unavoidable plot thread of the game.''

JC Denton is brought straight from training when the NSF attack Liberty Island. While he defeats them, a shipment of Ambrosia is stolen and taken to New York. JC takes on multiple missions tracking the NSF and the Ambrosia shipment, eventually finding out that Paul has defected to the NSF, acting as a mole within UNATCO after learning the Gray Death was a man-made disease used for power and population control. As punishment for his defection, Simons takes control and activates a [[kill switch]], giving Paul just 24 hours left alive. Ordered by Manderly to eliminate Tracer Tong in Hong Kong, JC instead finds Paul's hideout in New York, learning more details about UNATCO's operations but prompting his employers to attack him. JC's kill switch is also activated, and Paul can either escape or be killed by Simons' agents.

JC is taken to a Majestic 12 prison beneath UNATCO, but escapes with help from "Daedalus", initially assumed to be a hacker. JC travels to Hong Kong and finds Tong, getting help removing the kill switch in exchange for resolving a war between the Triads. Tong identifies the virus as created by VersaLife, Page's company and a former Illuminati asset. Destroying the [[molecular assembler|universal constructor]] creating the virus and stealing the Ambrosia plans, JC is then sent by Tong to the Illuminati's remaining base in Paris. JC finds Morgan Everett, who explains the Gray Death was intended as an aid to augmentation, but was stolen and repurposed by Page and Simons. To stop Page from producing more Gray Death, JC agrees to defend against Simons's assault on [[Vandenberg Space Force Base|Vandenberg Air Force Base]], where a group of Majestic 12 defectors are hiding with a second universal constructor.

JC learns from the Vandenberg scientists that Daedalus is an AI currently allied with Everett. When Everett attempts to defeat Majestic 12 using Daedalus, Page counters with his successor AI Icarus. The process causes Daedalus and Icarus to merge into a new entity "Helios", which seizes control of worldwide communication. JC must then travel to Area 51, where Page is in the process of merging with Helios to gain global power. JC is then given three options for defeating Page and resolving the situation. Tong wants the base destroyed, bringing down the world's communication network and triggering a "[[Dark Age]]" of free city states, Everett wants to preserve the technology and re-establish the Illuminati as the world's controllers, and Helios seeks to merge with JC and become a benevolent dictator.

|footer=Spector created the original concept for ''Deus Ex'' and acted as producer and director; Smith was lead designer.}}
The concept for ''Deus Ex'' was created by [[Warren Spector]], who first started writing its design document while working at [[Looking Glass Studios]] on ''[[Ultima Underworld II: Labyrinth of Worlds]]'' (1993). Initially titled "Troubleshooter", it laid out the basic gameplay ideas and real-world based setting.<ref name="GamaSpectre"/> During his work at [[Looking Glass Studios]] on ''[[System Shock]]'' and ''[[Thief: The Dark Project]]'', Spector was growing frustrated at creative limitations placed on him, and due to financial troubles Looking Glass Studio closed down their Austin branch where Spector worked.<ref name="DEIWgama"/><ref name="IonHistory"/> He was invited to join the newly founded [[Ion Storm]] by co-founder [[John Romero]], who offered Spector complete creative freedom on his next project. Spector eventually agreed and led the creation of Ion Storm's Austin studio where ''Deus Ex'' would be developed.<ref name="IonHistory"/>

Publisher [[Eidos Interactive]]'s former executive chairman [[Ian Livingstone]] described their decision to back ''Deus Ex'' as part of a strategy to broaden the company's portfolio away from ''[[Tomb Raider]]''. He felt Eidos were right to back the concept due to Spector's skills and ambition.<ref name="RPSretro"/> Pre-production began in August 1997 under the working title ''Shooter: Majestic Revelations''.<ref name="GamaSpectre"/><ref name="USGdeleted"/> Spector led the game's team as producer and lead director.<ref name="DEIWgama"/><ref name="IGNinterview"/> During the early stages he both helped run the new studio and hired staff for the game.<ref name="IonHistory"/> Team members included lead designer [[Harvey Smith (game designer)|Harvey Smith]], with whom Spector had worked at Looking Glass Studios, and Chris Norden as lead programmer and assistant director, and level designer Steve Powers.<ref name="DEIWgama"/><ref name="RPSretro"/> The team eventually expanded to twenty people,<ref name="GamaSpectre"/> split between two design teams and an art team led by Jay Lee.<ref name="NordenInterview"/> Production lasted twenty-eight months,<ref name="GamaSpectre"/> and the game was declared [[Software release life cycle#Release to manufacturing (RTM)|gold]] (indicating that it was being prepared for duplication and release) in June 2000.<ref name="DSEXgold"/>

===Game design===
The original design documented cited the gameplay inspirations as ''[[Half-Life (video game)|Half-Life]]'', ''[[Fallout (video game)|Fallout]]'', ''Thief: The Dark Project'', and ''[[GoldenEye 007 (1997 video game)|GoldenEye 007]]''; the game as a whole was meant to be "genre-busting".<ref name="GamaSpectre"/> Spector later cited the limited choices available in ''[[Suikoden (video game)|Suikoden]]'' as an inspiration for the broad range of story and gameplay options in ''Deus Ex''.<ref name="SilSpector"/> Spector's aim with the gameplay was to allow as much player freedom as possible; his design document and personal goals included "problems, not puzzles", "no forced failure", "players do; NPCs watch", and "areas with multiple entrance and exit points".<ref name="GamaSpectre"/> These early designs underwent extensive expansions and alterations during early production.<ref name="USGdeleted"/> An early commitment was making level areas open-ended, with multiple ways to resolve gameplay and story situations. The opening "[[Liberty Island (Deus Ex)|Liberty Island]]" was designed as a [[vertical slice]], showing off the various gameplay elements the team wanted to implement overall.<ref name="RPSretro"/> There were some limitations put in place such as restricting what and how many augmentations the player could have access to, which Spector explained as promoting variety between players.<ref name="IGNinterview"/>

The team opted to license a third-party engine for the game rather than building their own, which ultimately gave more time for story and gameplay development. They ultimately settled on the [[Unreal Engine 1|Unreal Engine]] as it would cover most of what they wanted to do from a design perspective, and was easy for their programmers to handle.<ref name="GamaSpectre"/> As the Unreal Engine was designed for first-person shooters, the RPG mechanics such as leveling and inventory were added by the developers, alongside additional graphical elements like lip syncing for dialogue.<ref name="CGWinterview"/> Programmer Scott Martin implemented a wide range of new NPC behavior including patrols, idling, and sitting down. During early testing the enemy reactions were so acute that Martin had to adjust their behavior and detection protocols to be more forgiving.<ref name="TechRetro"/> The AI coding caused problems until late into development, with the team building on Unreal Engine's existing code and causing unpredictable NCP behavior as a result.<ref name="GamaSpectre"/> Designer [[Doug Church]] provided help with some of the AI programming.<ref name="RPSretro"/>

Spector described the early high-concept work on the game as the smoothest period, with later production running into repeated issues. The game's scale and conflicting suggestions from playtesters began causing problems for the team. The production milestones necessitated trimming or altering features; Spector recalled Smith using the phrase "Less is more" in reference to these elements.<ref name="GamaSpectre"/> There were also conflicts between the two design teams headed by Smith and Norden, described by Spector as "a bunch of knock-down drag-out fights".<ref name="DEIWgama"/> The team's morale also suffered due to negative press surrounding Ion Storm during and after the release of ''[[Daikatana]]'' (2000).<ref name="GamaSpectre"/> Planned environments also needed to be scaled down.<ref name="EdgeMakingOf"/> Some content was cut entirely including a female option for JC Denton,<ref name="IGNpreview"/> and stages set in the [[White House]], [[Russia]], and on board a space station.<ref name="USGdeleted"/><ref name="IGNinterview"/> Finished elements from those levels were incorporated into the final story and levels.<ref name="USGdeleted"/> The feature Spector most regretting dropping was plans for multiplayer that would have featured at release, describing the other dropped content as "just kind of stupid stuff".<ref name="IGNinterview"/> By contrast, Martin was upset that those sections had to be cut, but understood they had to release the game due to troubles with Ion Storm's other titles.<ref name="TechRetro"/>

===Scenario===
The storyline drew from multiple sources, including ''[[The X-Files]]'', ''[[Colossus: The Forbin Project]]'', ''[[The Manchurian Candidate]]'', ''[[RoboCop]]'', and ''[[The Men in Black (comics)|Men in Black]]''.<ref name="GamaSpectre"/> Inspired by his wife's liking for ''The X-Files'', Spector connected the "real world, millennial weirdness, [and] conspiracy" topics to appeal to a broad audience.<ref name="GameSlice"/> While the initial story plan was described as similar to ''The X-Files'', Spector felt the final product was close in tone to ''[[James Bond]]''.<ref name="RPSretro"/> The story changed a lot during production, with supporting characters and antagonists changing a lot, but JC Denton's presence and role as a government agent remained consistent.<ref name="USGdeleted"/> Some of the plot's references were described as being "literally ripped from the headlines" such as references to the [[Trilateral Commission]] and modern protest groups. Spector later felt uncomfortable with how some in-game events unintentionally mirrored later real-life developments such as the [[September 11 attacks]].<ref name="EdgeMakingOf"/>

The script was principally written by Sheldon Pacotti.<ref name="RPSretro"/> Additional material was written by Chris Todd and [[Austin Grossman]]; Grossman focused on small verbal "barks" and rewriting conversations where needed, while Todd wrote in-game texts and the opening and ending cutscenes.<ref name="Pacotti"/> When Pacotti joined in 1999, all the characters had names and detailed backstories, with the main job being implementing the plans of Spector and Smith into the finished game. The pre-release script was very large, and the writing team were working constantly on it for six months.<ref name="PacottiInterview"/> Smith took the large draft script and trimmed it down, while designer Albert Yarusso created a dialogue management system.<ref name="RPSretro"/> The writing team were reading several books covering popular conspiracy theories of the time, and Grossman attributed the political elements to Spector and Pacotti. After Pacotti was hired, the story's tone shifted sharply towards the "conspiracy and socialist angle".<ref name="RPSretro"/> Pacotti enjoyed working on the story, writing for it constantly after being impressed by seeing Spector's playthrough of an early game.<ref name="EuroPacotti"/> In hindsight, Grossman felt embarrassed by some of the character stereotypes they used for NPCs in Paris and Hong Kong.<ref name="RPSretro"/>

The original design document had "dozens" of character concepts that survived into the final game, but had to be changed to fit design constraints.<ref name="USGdeleted"/> Due to how characters such as Paul could die, they could not be full incorporated into the second half of the game's story, but scenes related to them were put in place later in development to resolve their plot lines if they survived. These insertions were decided a meeting between Smith, Church and the script writers. Some of the uneven character representation was explained as being due to focusing on gameplay over story, with their additions being last-minute inclusions.<ref name="DXbible2"/> The endings were designed as isolated late-game choices independent from previous decisions made during within the game. Smith explained the decision as a way not to "trap" players into a particular route based on earlier decisions they might not understand.<ref name="DXbible3"/> Plans for an ending following on from the player either dying to or siding with Page were dropped due to time constraints.<ref name="DSEXbehind"/>

===Audio===
The music of ''Deus Ex'' was handled by members of Straylight Productions, a music group who had notably worked on the ''[[Unreal (video game series)|Unreal]]'' series.<ref name="StraylightResume"/> The main composer was [[Alexander Brandon]],<ref name="BrandonInterview"/> with additional work by [[Dan Gardopée]], [[Michiel van den Bos]] and [[Reeves Gabrels]].<ref name="StraylightResume"/><ref name="OSTinfo"/> Gabrels' contributions were the club songs for New York, Paris and Hong Kong.<ref name="Manual"/>{{Rp|21}} Speaking in 2007, Brandon remembered ''Deus Ex'' as his favorite project due to positive feedback from players.<ref name="BrandonInterview"/> As with their earlier projects, the music used the MOD [[module file]] format.<ref name="StraylightNews"/> The main theme was based on an unused music track created by Brandon for a cancelled ''Unreal'' project.<ref name="DEIWgama"/> ''Deus Ex'' was Brandon's last game as a member of Straylight, as he moved to Ion Storm as head of their audio department.<ref name="StraylightNews"/>

Speaking about the voice acting, Brandon described it as "really cheesy" but effective due to it communicating the different characters' personalities quickly.<ref name="DEIWgama"/> Both JC and Paul Denton were voiced by Jay Anthony Franke, an aspiring voice actor who was working in QA at Ion Storm at the time. Franke estimated his lines totaled between 11,000 and 14,000 words. As he was also a QA tester for the game, his lines were added in very late by the sound team so he would not have to listen to himself during testing.<ref name="Franke2012"/> Spector estimated that the game had around 150,000 lines of voiced dialogue, which was localized into European languages for its release on those regions.<ref name="EuroPreview"/>

==Release==
During production, the game was originally planned for a release around Christmas 1998, but was repeatedly pushed back due to production problems.<ref name="USGdeleted"/> By 1998 the title had become ''Deus Ex'', taken from the phrase "[[deus ex machina]]" originating in ancient theater and typically meaning an unexpected person or figure resolving a situation without warning.<ref name="CGWinterview"/><ref name="RPGFinfo"/> Spector described the title as a multilayered wordplay on the story's themes, the difficulties of game plots, the concept of a computer game, and a "self-referential" acceptance of trying one's best to resolve affairs.<ref name="RPGFinfo"/> The game was shown off at the 1998 [[European Computer Trade Show]],<ref name="EuroPreview"/> and first previewed at [[E3 1999]].<ref name="E3deusex"/> As part of the marketing, the team created an authentic-looking website for UNATCO and linked it to pre-existing government websites; excessive traffic from the UNATCO page caused one of those websites to crash, prompting a call from that agency's lawyers.<ref name="EdgeMakingOf"/>

''Deus Ex'' was published by Eidos Interactive during 2000 on [[Microsoft Windows]]; June 23 in North America,<ref name="NAdatePC"/> July 27 in Australia,<ref name="AUdatePC"/> and the United Kingdom on August 4, 2000.<ref name="UKdatePC"/> The game was supported after release with software patches to resolve framerate issues with [[Direct3D]],<ref name="DSEXupdateA"/> and introduce the multiplayer mode.<ref name="Multiplayer"/> A ''Game of the Year'' edition was released on May 8, 2001, incorporating the additions and including a soundtrack CD.<ref name="GotYdeus"/> The ''Game of the Year'' edition was released through [[Steam (service)|Steam]] on March 29, 2007.<ref name="DeusexSteam"/>

Versions for [[Classic Mac OS|Mac OS]] and [[Linux]] operating systems were being planned during the game's production.<ref name="GamaSpectre"/> The Mac OS port was in development at Westlake Interactive prior to the PC version's release.<ref name="Westlake"/> The Mac OS port was published in North America by [[Aspyr]] on July 13, 2000,<ref name="MacDate"/> and was patched to fix technical issues and introduce multiplayer.<ref name="WestlakePatch"/><ref name="MacMultiplayer"/> A Linux port was in development at [[Loki Entertainment|Loki Games]] before the company closed down in 2002.<ref name="LokiDSEX"/><ref name="LokiDown"/>

===''Deus Ex: The Conspiracy''===
A port of the game for [[PlayStation 2]], titled ''Deus Ex: The Conspiracy'' outside Europe, was published by Eidos Interactive during 2002; it released in North America on March 26,<ref name="DSEXps2UKNA"/> in Europe on June 7,<ref name="DSEXps2UK"/> and in Australia on December 13.<ref name="DSEXps2AU"/> The port was developed in-house by Ion Storm with a team of fourteen people, many drawn from the original team.<ref name="GSinterview"/><ref name="DXMinterview"/> Spector described the largest issue with the port being the PS2's limited memory space, since Spector wanted the game ported over with as much content intact as possible.<ref name="CVGinterview"/> As part of porting, the level maps were streamlined or re-arranged,<ref name="GSinterview"/> the difficulty and augmentation mechanics were rebalanced,<ref name="MGONinterview"/> and the interface had to be fully redesigned to be understandable and easily usable for console users.<ref name="DXMinterview"/>

The initial design document as described by the port's producer Bill Money called for the levels to be redesigned with ending [[Boss (video games)|boss]] fights, which caused him to "flip".<ref name="MGONinterview"/> While the original character models used a [[Polygon mesh|mesh]]-based design, the PS2 version was updated to a [[Skeletal animation|skeletal]] model for more realistidc movement.<ref name="GSinterview"/> Motion capture was also added for male and female models.<ref name="MGONinterview"/> The release was delayed by a couple of months due to the need for optimisation to decrease [[load times]] and the burden on console memory. The frame rate issues required a lot of the game's code to be moved from the Unreal-native environment into [[C++]] format.<ref name="GSinterview"/>

===Mods===
The [[software development kit]] (SDK) for ''Deus Ex'' was released on September 22, 2000,<ref name="DSEXupdateB"/> and shortly thereafter, fans of the game began to create [[Video game modding|mods]].<ref name="GSpyMods"/> In a press release related to the patch, Spector and other team members stated they were eager to see what the modding community would make.<ref name="PressMods"/> Notable mods include ''[[The Nameless Mod]]'' (''TNM''), a "total conversion" released in 2009;<ref name="PCPPnameless"/><ref name="PCGnameless"/> ''Deus Ex: Revision'', a publisher-endorsed mod released in 2015 that overhauled the game's graphics, gameplay and soundtrack;<ref name="Revision"/> and ''The Lay D Denton Project'', a 2021 release which restores a female JC Denton with new voice acting and adjustments to existing voice lines to account for the gender change.<ref name="LayDDenton"/>

== Reception ==
===Sales===
According to ''[[Computer Gaming World]]''{{'}}s Stefan Janicki, ''Deus Ex'' had "sold well in North America" by early 2001 with regular placement in top ten best-selling lists for several weeks, and showed even better performance in Europe with similar sales position throughout the summer of 2000.<ref name="desslocksales"/> The game achieved sales of 138,840 copies and revenues of $5 million in the United States by the end of 2000, according to [[PC Data]].<ref name="pcgsales4"/> It received a "Silver" award from the [[Entertainment and Leisure Software Publishers Association]] (ELSPA) in February 2002, indicating lifetime sales of at least 100,000 units in the United Kingdom.<ref name="100k"/> The ELSPA later raised it to "Gold" status,<ref name="goldelspa"/> for 200,000 sales.<ref name="gamasutrasales"/> As of April 2009, ''Deus Ex'' has sold over 1 million copies sold worldwide.<ref name="DEIWsales3"/>
