Arkane Studios have announced the first slice of DLC for the recently-released (and pretty damn good) Dishonored.
The DLC - Dishonored: Dunwall City Trials - will include 10 challenge maps that will test and track your combat, stealth and mobility skills. There'll be online leaderboards for each map, as well as a slew of new achievements and trophies.
This DLC will release sometime in December 2012, simultaneously on the PlayStation 3, Xbox 360 and PC for £3.99/$5.00/400 MS Points.
If you prefer story-driven DLC then the second and third add-on packs will probably be of more interest to you. The second DLC pack will focus on Daud, the leader of a gang of assassins called The Whalers. Look out for those sometime in 2013.
