Dishonored's "The Brigmore Witches" will conclude the steam punk DLC on August 13 for Xbox 360 and PC and August 14 for PlayStation 3.
It follows on from the previous DLC pack "The Knife of Dunwall" with the assassin Daud.
After discovering the identity and intentions of Delilah, Daud must stop her from carrying out a powerful ritual that would spell the end for him.
Having accepted the betrayal of Billie Lurk, you have to rely on feuding gang factions the Dead Eels and the Hatters to navigate new areas of Dunwall.
All previous weapons and abilities carry over from the last DLC pack and a joined by new powers including Pull and Summon Assassin — which are pretty self-explanatory.
