Game of the Year Edition. Can be played without Steam using Deus Exe.
Several demo versions of Deus Ex are available at Planet Deus Ex, including the first two missions as well as a Macintosh version.

Version differences[edit]

While the Steam version is cheaper, the version has no DRM, cloud saves and offers free bonus content.

Essential improvements[edit]

Community Update[edit]

The community update includes every translation, patch, alternate exe, and renderer known; As well as many useful tools for players and modders.
Also includes the original demo files which you can apply the multiplayer patch to. This lets you play the full multiplayer and single-player up to the end of mission 2! Minor updates to some of the included projects have been done and more is planned.
Depending on your system, may be slow to install.
Currently no uninstaller. Though easy to manually do.
Install is relatively inefficient, taking about 3gb total to install. This includes the 1gb size of the installer. Final install size is 1gb.


The 1.112fm patch fixes various bugs and adds multiplayer.
Digital distribution versions already include this patch as do some retail re-releases.
This patch unintentionally removes music from the Hell's Kitchen map on your last visit, as well as introducing other map bugs. The problem is present in all GOTY releases. Except for one you manually patched yourself, which will also be missing the new conversation files. Note that though the GOTY version introduces noticeable bugs, it also fixes many. An in depth file comparision along with relevant links are available here.

Deus Ex Maps Patch[edit]

D.X.M's Deus Ex Maps Patch replaces the maps from the 1.112fm patch with the 1002f ones and fixes various bugs, but also introduces some. Up to player preference which set of maps you use.
This patch does not replace the multiplayer maps for compatibility reasons.
These files are identical to the original release maps - with the exception of 3 actually unique files. More information, a link to the 3 vanilla files, as well as bug&difference reporting available here.


Confix repairs dialogue typos and logic errors in conversations. (English only)
Seems to mess up some audio reactions of NSF npcs, at least in the first level.

Unofficial Patch v2[edit]

The Unofficial Patch v2 fixes additional bugs and cheats.

Deus Exe[edit]

Kentie's Deus Exe is an updated executable that integrates support for various features.
This fix will replace the existing deusex.exe file within the folder. If you want to be able to uninstall it, backup the main executable beforehand.
Does not work with the GameStop (Impulse) version of Deus Ex. Instead use the Custom launcher combined with the OTP UI Fix or Peixoto's patch.
FPS limiter in new versions of DeusExe causes freezes when opening menus. See Game freezes when opening menus.[1]
Using Deus Exe
  1. Install Deus Ex normally. For CD versions you must choose the full install option.
  2. Download the latest version of Deus Exe (If using Windows XP download 5.3 version instead)
  3. Install Microsoft Visual C++ 2015 Redistributable Package (x86).
  4. Extract the Deus Exe files to <path-to-game>\System folder, replacing the existing deusex.exe when prompted.
  5. Set your options in the pre-game launcher.

Direct3D 10 renderer[edit]

Kentie's Direct3D 10 renderer improves compatibility with modern systems and adds native support for various features including anti-aliasing, anisotropic filtering and multi-monitor resolutions.
This renderer may exhibit stuttering and performance issues with Nvidia driver 442 or newer.[2][3]
  • If you are using Deus Exe, install the renderer then choose Direct3D 10 Support in the launcher.
  • If you are using the original Deus Ex, install the renderer then run Deus Ex in Safe Mode and choose Direct3D 10 Support from the list.

DirectX 11 renderer[edit]

A fork of Kentie's Direct3D 10 renderer that adds more graphical features, including ambient occlusion, screen space reflections and higher quality HDR post-processing.

Restore 3D sound[edit]

Use OpenAL Soft[14]
  1. Download the ALAudio for Deus Ex mod, and copy all of its contents (not the folder) to <path-to-game>\System.
  2. Open DeusEx.ini and change the line AudioDevice=Galaxy.GalaxyAudioSubsystem to AudioDevice=ALAudio.ALAudioSubsystem. Copy the settings at the bottom of the post here at the end of the .ini file. Replace UseHRTF=Autodetect with UseHRTF=Enable.
  3. Follow the instructions on this guide. Make sure to use OpenAL Soft 1.18.2 instead of later versions to create the .mhr files. During step 11, set the Period Count to 2.
If you are using Deus Exe, make sure to edit DeusEx.ini in %USERPROFILE%\Documents\Deus Ex\System\.
Lipsync is faster than it normally should be with the included OpenAL32.dll and lipsync will not work if you replace the included OpenAL32.dll with the one from OpenAL Soft.[13]

Stuttering with DX10 renderer enabled (NVIDIA Graphics cards)[edit]

Install driver version 442.74 or lower[15]
  1. Download the installer from Nvidia's website
