Titan Quest: Atlantis

Titan Quest: Atlantis is an add-on for the action RPG Titan Quest. It adds a new story campaign set in the western Mediterranean, following a search for Atlantis. The expansion supports single-player and co-op play for up to six players, introduces new items, and features expanded masteries with additional skill tiers. Quality-of-life improvements, visual upgrades including SSAO and color grading, and a Casino Merchant for spending excess in-game currency are also included. A new Tartarus Endless Mode offers a wave-based challenge with randomized elements.
