According to Dishonored developer Arkane, the final add-on pack for the game will be launching next month.
The campaign will see the players conclude the story of Daud, the assassin who killed the Empress at the beginning of the main game. The DLC will be priced at 800 MS points on the Xbox 360 and £7.99/€9.99/$9.99/AU$14.45 on PS3 and PC.
In The Brigmore Witches, continue your journey as the legendary assassin, Daud, and bring his twisted narrative that began with The Knife of Dunwall to a close. After discovering the identity and intentions of Delilah, the leader of the Brigmore Witch coven, you set out to disrupt her from completing a powerful ritual that will spell your doom.
Having already been betrayed by your lieutenant, Billie Lurk, you must rely on feuding gang factions-the Dead Eels and the Hatters-to negotiate your way through previously unseen districts of Dunwall en route to Delilah's stronghold. Regardless of the way you reach your destination, one thing is for certain - you will finally answer for your treacherous actions and fall before the mercy, or punishment, of the Royal Bodyguard and Assassin, Corvo Attano.
