Essential improvements[edit]


T2Fix 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 The GOG release has an out-of-date, stripped-down version of tafferpatcher(discontinued).

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 here (choose the 'ZIP-archive' link).
Running Fan Missions[citation needed]
  1. Select the option to create a shortcut to the FM Selector during T2Fix 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[citation needed]
  1. Go to the installation folder.
  2. Open cam.cfg using Notepad.
  3. 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 T2Fix and is much less comprehensive). This contains higher quality reproductions of many but not all 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.).

Thief 2 ESRGAN Texture Pack[edit]

Thief II: The Metal Age textures upscaled using AI, more accurate to the original textures than other texture packs, but of less resolution than the alternatives. It is far higher in resolution and detail than the original textures however. Can be found at this Through the Looking Glass forum post or at ModDB.

Thief 2X ESRGAN Texture Pack[edit]

AI upscaled textures for unofficial Thief II expansion - Thief 2X: Shadows of the Metal Age. Includes upscaled textures and HQ Paintings Pack.

Thief 2 HQ Paintings Pack[edit]

Standalone addition of the ESRGAN mod for Thief Gold and Thief II: The Metal Age. All paintings from the game being manually recreated using real life originals from online galleries in HQ 1024x1024 resolution. ModDB Link.

Additional mods[edit]

Sound effects enhancement pack[edit]

This mod provides cleaned up and resampled sound files for Thief Gold and Thief II. The quality difference is particularly noticeable when wearing headphones.

Filtered Cinematics pack[edit]

Video Pack provides filtered cinematics with 15->30 fps conversion, compression artifacts removal and deinterlacing some of the original videos. Requires T2Fix to work. ModDB link to Upscaled Cinematics
It's a part of the Thief 2 ESRGAN Texture Pack.
