Dishonored, the first person stealth/action-game from Bethesda and Arkane Studios, will be getting its first DLC add-on come December 11th.
Called the Dunwall City Trials, this add-on will test your skills in various ways like fighting a wave of enemies or doing a perfect run of drop assassinations. New achievements/trophies will also be available, as well as an unlockable image gallery and online leaderboards. You know, just in case you want to see how well you measure up.
Dishonored: Dunwall City Trials releases on PC, Xbox 360 and PS3 for 400 MS Points/$4.99.
