Essential improvements[edit]


Tafferpatcher installs NewDark, which improves compatibility on modern systems. Also contains mission fixes and optional texture mods. The GOG release has an out-of-date, stripped-down version of this patch.

Fan Missions[edit]

A large number of Fan Missions, many of very high quality, have been produced for the Thief games. A categorised list is available here.
A pre-patched version of Thief2X, the fan-made expansion pack for Thief 2, can be downloaded from this thread.
Running Fan Missions
  1. Select the option to create a shortcut to the FM Selector during Tafferpatcher installation. If you did not check this option, add the command line argument -fm on a Thief desktop shortcut or in the Steam interface.
  2. Start FM Selector using this shortcut.
  3. Select a folder for installed missions and an FM .zip archive path when prompted. Do not put the archive path inside the FMs folder or vice-versa, otherwise things will not work correctly.
  4. To install a mission, drop its .zip file (do not extract it) into your chosen archive path, start the selector, double click the mission/zip file name and select 'Ok'. It has now been extracted to the installed missions folder.
  5. Launch the mission by double clicking the name again. To launch the original game select 'Skip FM' in the lower-left corner.

Skip intro videos[edit]

Tell intro not to play
  1. Open cam.cfg in the game folder, using Notepad.
  2. Add the line skip_intro to the file and save it.

Texture mods[edit]

Enhancement Pack 2.0[edit]

The Enhancement Pack 2.0 is an updated version of the original Enhancement Pack (which is included in Tafferpatcher and is much less comprehensive). This contains higher quality reproductions of original textures and objects. Also works with Thief Gold/The Dark Project.

The Necro Age[edit]

The Necro Age pack is very similar to the Enhancement Pack 2, but focuses on giving the game a slightly darker, noir look. Somewhere between the EP2 and HD Mod in lore-accuracy. Also works with Thief Gold/The Dark Project.

Thief 2 HD Texture Mod[edit]

The Thief 2 HD Texture Mod adds new textures and effects to all original missions. Includes a tool to configure advanced graphics settings (Anti-Aliasing, Bloom, etc.).
