  1. Open <path-to-game>\Engine.dll with a hex editor such as HxD.
  2. Change offset 0x164A0F to 0x11 (from 0x01) and offset 0x164A11 to 0x02 (from 0x03).
  3. Save

Other information


Technical specs Supported Notes
Direct3D 9.0c
Shader Model support 1.1
Executable 32-bit 64-bit Notes



Extensive mod that raises the level cap to 85 (from 75) and introduces new content as well as balance, making the game more difficult overall but close to its original style. 1.17a patch is embedded.

Other utilities

TQ Vault

Acts as an external, independent, shared inventory. It can create unlimited Vaults, useful for creating collections of rare items or "twinking" (giving characters items found by other characters, generally from later parts of the game and higher quality). It also has some item-editing features, such as the ability to change a relic's completion bonus, clone items or complete sets. Users of the Steam version of Titan Quest cannot use this tool, as use will likely result in corruption of all characters edited by the program.


Middleware Notes
Multiplayer GameSpy GameSpy features do not work. The Steam version has a beta update that resolves this.[6]
