I dont yet even own the game but Arkane Studios have announced the DLC schedule for their highly acclaimed stealth title Dishonored, with the first pack coming in December known as Dunwall City Trials (400 msp & $4.99 on PSN and PC).
It will include 10 new challenge maps. The challenges include a battle arena where you will combat waves of enemy AI, a gravity-defying run of drop assassinations, and a race against the clock. Dunwall City Trials will of course come complete with new achievements and trophies to unlock as well as an online leaderboard.
The 2nd and 3rd packs will be coming in 2013 and will feature full story driven campaigns.The first will feature a character named Daud, the leader of a group of supernatural assassins known as "The Whalers." which is scheduled to come out in spring 2013. No details have been released on the 3rd pack as of yet.
