Dishonored's first DLC, Dunwall City Trials, is set for release next month. The DLC will be available on December 11 for PlayStation 3, PC and Xbox 360 and will cosr $4.99 and 400 Microsoft Points respectively.

Dunwall City Trails doesn't seem to add any substantial story content to Dishonored, bit it does add new achievements and trophies. It looks like it takes place in the weird Outsider world, and puts players through a series of trials across 10 challenge maps. You can check out some screenshots from the DLC below.
