Dishonored's "The Knife of Dunwall" downloadable content pack is the type of meaty addition we're looking for from an expanded universe experience. If you've yet to play Dishonored and are sensitive about spoilers, we'd actually recommend not watching the above trailer, as it revolves around the the opening moments of the game. However, it's the central idea of why the assassin Daud, who you'll play in this expansion, is having a bad couple months.
Daud's quest for "Delilah" will begin on April 16. It'll cost $9.99 in whale oil or its equivalent to play the add-on pack for Xbox 360, PS3 and PC.
