Source Digital Spy Dishonored's 'The Knife of Dunwall' DLC has been announced by Bethesda. The story-driven DLC, which was recently teased with an image, sees players assume the role of Daud, the assassin who killed the Empress at the beginning of the main campaign. Daud's story will see the assassin discover the mystery behind Delilah, earning redemption or turning further towards darkness depending on players' actions. In addition to new weapons, powers and gadgets, players will be able to explore new areas such as the Rothwild Slaughterhouse, which is filled with whale carcasses and hulking butchers. New actions include the ability to summon whalers with the Summon Assassin power and discover hidden objects with Void Gaze. Existing powers will also receive unique upgrades. The two-part DLC will conclude with the release of 'The Brigmore Witches', details of which will be announced at a later date. 'The Knife of Dunwall' will be available to download on Xbox 360, PS3 and PC on April 16. It will cost 800 Microsoft Points (£6.80/$10) on Xbox 360, while the PSN and PC versions will be priced at £7.99/$9.99.
