Essential improvements[edit]


TFix updates the game for modern systems. Using it is highly recommended. The version already includes some TFix changes.

Enhancement Pack[edit]

The Enhancement Pack replaces low quality objects and textures with versions that have higher polygon counts and texture resolutions. It is already included in TFix.

Thief Gold HD Texture Mod[edit]

The Thief Gold HD Texture Mod is a pack with HD textures and new effects. It is only compatible with Thief Gold. Note: Makes the game more de-saturated and changes its graphical style in a way some may not like (far more than the Enhancement Pack 2.0 does). A FAQ with installation steps is available.

Enhancement Pack 2.0[edit]

The Enhancement Pack 2.0 is an improved version of the Enhancement Pack, with better textures and modified terrain textures. It also applies changes to Thief 2.
