Dishonored: The Brigmore Witches, the last installment in Daud's story, is due soon and, as always, there are achievements to be had. But what kind, and what story hints do they drop? There's a list here just for you, but if you don't want to know what's coming, best hide your eyes, or at least lend them to a passing stranger for ten minutes or so.
Breakout: Break Lizzy Stride out of Coldridge Prison.
Gangs of Dunwall: Restore the Undine to working condition.
Deal Maker: Purchase at least 8 favors.
All Come To Ruin: Complete The Brigmore Witches in High Chaos.
Changed Ways: Complete The Brigmore Witches in Low Chaos.
Silence Is Golden: Complete The Brigmore Witches without alerting anyone.
Cleanest Hands: Complete The Brigmore Witches without killing anyone.
Enough Coin To Disappear: Survive The Brigmore Witches in low chaos with 10,000 coins.
Parting Shot: You delivered (or attempted) the killing blow on Corvo.
Wall Of Flesh: You used an enemy lifted with Pull as a shield.
So Corvo will be returning for this one, but in what context? Is this a flashback scene to the assassination of the Empress - an event which takes place before the DLC - or something else? You'll have to wait a while to find out. This one's due August 13 for the Xbox 360, PlayStation 3 and PC, and will cost $9.99 (800 Microsoft points).
