Dishonored's first story based DLC, The Knife of Dunwall, has been launched on Xbox 360, PS3 and PC. The expansion will be available tomorrow for European PS3 owners.
To accompany the launch Bethesda have also re-released a gameplay trailer. In the footage, Daud, the assassin players take the role of in the DLC, discusses his murder of the empress and shows him using a variety of powers including teleportation and Stun Mines which send out waves of electricity to strike nearby foes. The DLC also adds a conceiled Wristbow for sending out sleep darts or explosive rounds.
"I've killed nobles before, why should an empress be different?" Daud asks and the trailer actually shows the moment in which he commits the assassination.
The Knife of Dunwall sees Daud accompanied by his fellow assassins, the whalers, and sees the return of the enigmatic Outsider who commented on Corvo's actions during the main story as well handing out mysterious powers. The DLC adds the Slaughter House and Legal District areas and also allows gamers to return to the Flooded District.
You can pick up The Knife of Dunwall for $9.99 or 800 Microsoft points.
