The Dishonored website now offers a new trailer showing off gameplay from The Knife of Dunwall add-on that's due next week for the stealth/action game. Here's word on the add-on:

In The Knife of Dunwall you take on the role of Daud, the legendary assassin who killed the Empress, and access his weapons, gadgets, allies and supernatural abilities. After assassinating the Empress, and forever changing the fate of Dunwall, you embark on a search for redemption. The Outsider reveals the key to your atonement, but who—or what—is Delilah? Accompanied by the Whalers, your loyal band of mercenary assassins, your search will take you through never-before-seen districts of Dunwall as you face off against new and terrible foes. Employ a unique arsenal of new weapons and powers that enhance Dishonored’s dynamic combat, mobility and stealth systems. In the struggle to hang onto the last shred of your humanity, the choices you make will ultimately determine your fate.

The Knife of Dunwall is slated for release worldwide on April 16, 2013 for Xbox 360, PS3 and PC for $9.99 (or 800 Microsoft Points). For more information on Dishonored or The Knife of Dunwall please visit www.Dishonored.com.
