Square Enix announced a new downloadable content (DLC) pack for Dungeon Siege III that will be available in October. The pack, Treasure of the Sun, adds several hours of gameplay, a new plot arc, additional quests, new enemies and tons of new loot.

The pack takes place beyond the borders of Ehb to an all-new environment: the Aranoi Desert. On their search for a lost Legion hero, players will fight through hordes of new villains only to find a forgotten abbey hiding a long-lost secret: the greatest treasure of the Azunite faith.

Further supporting the hours of new content in the expansion, developer Obsidian Entertainment has introduced several refinements to the systems and mechanics of the game including a new level cap of 35, new abilities, more monsters and items, and a new enchanting system.

Treasure of the Sun will be released in October for $9.99. Players can download the DLC via Steam (Windows PC), Xbox LIVE and the PlayStation Network.
