As promised, Fable III's first DLC add-on, 'Traitor's Keep' has just gone green on Xbox Live.
The 560 Microsoft Points add-on (that's about £4.80) adds new areas, quests and Achievements to the Lionhead adventure.
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."
Last week Microsoft also confirmed the release of Fable 3 on PC for May 17 in US, and May 19 in Europe, New Zealand and Australia.
