The game mostly consists of the same dialogue and area layouts as the PC version aside from some minor changes: e.g. the layout of Liberty Island. This was due to the fact that the PS2 version had smaller sectioned maps compared to the PC counterpart. The game also uses higher-resolution character models with lower-resolution textures.
Other notable changes are the fact that the game uses pre-rendered high polygon CGI cutscenes during the intro and the three endings rather than the in-game graphics that the PC version uses. This, coupled with the slightly better graphics, are largely considered to be improvements. Despite this, the PS2 version of Deus Ex is often overlooked and is far less well-known than (and largely thought to be inferior to) the PC original.
On May 16th 2012, the game was made available for the PlayStation 3 as a PS2 Classic; but only in Europe.
