Thief II: The Metal Age is a singleplayer first-person stealth and immersive sim game in the Thief series.

The game was the final title by Looking Glass Studios, as the studio would shut down a mere two months after release.

The retail version of the game has significant issues running out-of-the-box (e.g. stability, rendering, cutscene codec breaking after a few sessions). Several unofficial patches have been created over the years, most notably the NewDark engine and T2Fix.

Essential improvements

Unofficial Patches


NewDark is an fan-developed update patch to the Dark Engine that gets Thief II: The Metal Age to run on modern systems.

T2Fix already includes the latest version of NewDark.

OldDark Legacy Patch

Allows the original (aka OldDark) engine to run on modern systems.
Also available for Thief: Gold
Not as stable as NewDark, but more true to the original experience.


T2Fix is an "upgrade" patch that updates the game with NewDark, which improves compatibility on modern systems.

Features many mission fixes and optional texture mods.
The GOG release has an out-of-date, lite version of this patch.
Unlike the GOG release, the Steam release does not use T2Fix.
Restart the current mission (or progress to the next one) after patch installation, otherwise various issues may manifest, such as torches that do not properly go out when extinguished.

Fan Missions

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.

Texture mods

Enhancement Pack 2.0
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
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
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 (mirror)
Thief II: The Metal Age textures upscaled 4x 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. Provides more vanilla looking but HD look for the game.

Thief 2X ESRGAN Texture Pack
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
Standalone addition to 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. Could be used with any other modifications.

Additional mods

Sound effects enhancement pack
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
Video Pack provides filtered cinematics with 15 to 30 fps conversion, compression artifacts removal and deinterlacing some of the original videos. Requires T2Fix to work. It's a part of the Thief 2 ESRGAN Texture Pack, but can be installed standalone.
