The Titans have escaped their eternal prison, wreaking havoc upon the earth. The gods seek a hero who can turn the tide in an epic struggle that will determine the fate of both men and gods.

For its 10 year anniversary, Titan Quest will shine in new splendour. This Anniversary Edition combines both Titan Quest and Titan Quest Immortal Throne in one game, and has been given a massive overhaul for the ultimate ARPG experience.
