Priced at 800 Microsoft Points ($10), the add-on for the open-world Xbox 360 action-RPG packs an entirely new landmass--Knothole Island--along with three new dungeons, various new items, new weapons, and multiple new characters to interact with.

The pack, originally expected in December, will be accompanied by a free update that adds several other items to the game--"including Knight's Boots, Assassins Gloves, a special Weight Loss Potion, collectible silver book and more"--and permits those that haven't bought the DLC to still engage in online co-op play with those that have.
