===''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"/>
