Even assassins have to answer for their deeds, and Daud – the legendary Knife of Dunwall in Dishonored – is no exception. Killing the Empress and its subsequent effect on the city has a particularly heavy price, but there is redemption.

This official trailer for the upcoming story-based DLC shows off some of the powers and weapons you'll use as Daud as he seeks to clear his conscience with the help of The Outsider. You'll roam through new sections of the city as you search for someone of something called Delilah with your loyal band of mercenaries known as The Whalers.

The Knife of Dunwall DLC is available for the PC, Xbox 360, and PlayStation 3 on April 16 for $9.99 or 800 Microsoft Points.
