The 'Trailtor's Keep' add-on DLC for Fable 3 on Xbox 360 will arrive on Xbox Live Marketplace on March 1 for 560 MS Points.
In Microsoft's words: "The Traitor's Keep game add-on continues the journey as fans venture into three new levels called Ravenscar Keep, Clockwork Island, and the Godwin Estate, taking on new quests and encountering a mysterious prisoner. Traitor's Keep also comes packed with 250 gamerscore points and additional content."
New screenshots of the download pack are below (give it a couple of minutes and hit F5 if they don't appear instantly - our screenshot machine is doing overtime).
Microsoft also today confirmed the release of Fable 3 on PC for May 17 in US, and on May 19 in Europe, New Zealand and Australia.
This comes after the PC game, which was originally intended for release alongside console versions last year, was delayed in order to "optimise" it for the platform.
