Dishonored invites players to participate in the "Dunwall City Trials" on December 11. The first add-on pack for the game includes "10 challenge maps," that publisher Bethesda notes will have players battle waves of various enemies, test their supernatural assassination skills and "take out targets in a non-stop run of drop assassinations."

Dunwall City Trials will cost $5 (400 MSP) and will be available worldwide in two weeks for Xbox 360, PS3 and PC.

Bethesda previously stated Dishonored would add a second and third DLC pack in 2013, with the future content focusing on story-driven elements. Supernatural assassin Daud will be the focus of the second pack, which the publisher mentioned would be available in "spring 2013."
