Dishonored will received three DLC packs, beginning in December with the release of the Dunwall City Trials.
Priced £3.99/400 MS Points, Dunwall City Trials will include 10 challenge maps, including an arena battle against waves of enemy AI, a gravity-defying run of drop assassinations, and a race against the clock.
Dunwall City Trials also features a whole new set of achievements and trophies as well as a global online leaderboard for each challenge.
Coming in 2013 will be two further DLC packs, each promising story-driven campaigns. Daud, the leader of a group of supernatural assassins known as The Whalers, will be the focus of the second add-on pack, scheduled for release in early spring 2013.
Details on the third DLC pack will be revealed next year.
