The Anniversary Edition of Titan Quest includes the base game with the Immortal Throne add-on merged into one game. Additional coding was made to improve the performance and stability of the game, as well as resolve bugs and exploits, support more resolutions, rebalance the game, restore multiplayer with in-built voice chat and NAT resolving, and improve AI. New characters and bosses are also included, while challenges and rewards for larger parties are increased.
It was created for the tenth anniversary for the game. Owners of the base game, the Immortal Throne expansion or Titan Quest: Gold Edition on a digital platform like GOG or Steam can receive the full content of this version for free.
