According to Eurogamer, it will be called "The Other Side of the Coin" and will be story-based, with similar achievements to the main game (e.g. achievements for low chaos, for not alerting anyone etc). The DLC will take players to a location called Rothwild Slaughterhouse. Greedily, I can only hope that (with the other reserved domain names too) that we will see SEVERAL DLC packs in the future. Alas, no date of release has been annouced.

I just can't wait!! I blame Arkane entirely for my hopeless new addiction.

I hope we get to see some new enemies ,weapons etc.

Glad to hear we'll be visiting a whale slaughterhouse. I always found it odd that Dishonored never really explored Dunwall's whaling industry, or what was left of it. Still, that's great news! I'm looking forward to seeing what Arkane is doing with the new DLC.

"The Other side of the coin"= "You and me are both one and the same, we kill for others"=DAUD

They've already said that Daud will get his own set of powers and gear in the new DLC.
