Dishonored - New Story DLC
The people at PS3Trophies have spotted some new trophies for an yet unannounced Dishonored DLC named The Other Side of the Coin. The 10 trophies are at the bottom of this list.
Based on available information the second and third DLC for Dishonored are supposed to be story based, which would be applicable to this DLC, but as this list is the only information available we'll have to wait and see.
