The first bit of premium-priced downloadable content for Lionhead's open-world action-RPG Fable II (360) will arrive on December 12, publisher Microsoft has revealed.

Priced at 800 Microsoft Points ($10), the Knothole Island DLC pack adds the remote island of Knothole to the game. As Microsoft put it, Knothole is "where new quests, wondrous items and bizarre characters await."

In addition, a free download pack will arrive on the same day, rewarding players with "show of gifts, including Knight's Boots, Assassins Gloves, a special Weight Loss Potion, collectible silver book and more."

The free download will also enable players to play co-op with someone who has already bought the Knothole Island content, though both players will have to purchase the Knothole Island pack in order to play in that area together.
