Liked Dungeon Siege III well enough to spend another $10 or 800 Microsoft Points on it? DLC is your answer! Dungeon Siege III: Treasures of the Sun is now available on PC, Xbox Live Arcade and PlayStation Network. It's set in the Aranoi Desert (hence the Sun part?) with mummies and giant skellingtons to fight and a lost Legion hero to find.
The DLC will add a few new abilities, raises the level cap from 30 to 35, adds new items, allows you to respec your character throughout the campaign, and adds a new enchanting system. By transmuting items you'll have a chance of creating "Vials" that let you enhance your equipment.
If you were a big fan of Dungeon Siege III, this sounds like enough to give it a couple more playthroughs. And no, the DLC does not come with a new co-op camera system.
