The newly announced Dishonored: The Brigmore Witches DLC will take place shortly after the Knife of Dunwall DLC where players will need to disrupt the leader's plan of the Brigmore Witch coven.
The below screenshots shows some new Victorian era, steam punk environments set in both cities and areas with overgrown plant life. In addition to the new areas you will explore along the way, the gallery includes some concept of the new characters you will meet.
Since The Brigmore Witches DLC will continue from the Knife of Dunwall DLC, players with their completed saves can carry over their powers, weapons and upgrades.
The Brigmore Witches DLC will release on August 13th for PS3, Xbox 360 and PC for $9.99 or 800 Microsoft points.
