The Trophies list accomplishments for a new mission entitled "The Other Side of the Coin," including High and Low Chaos completions suggesting a story-oriented add-on. A few new locations also appear, sticking with Dunwall's theme of industrialized aristocracy with mention of a Rothwild Slaughterhouse and the estate of Thalia Timish.
Here's the full Trophy list:
If the Trophies suggest what we think they do, I'd like to see a deeper exploration of some of Corvo's more dramatic encounters within Dunwall, such as with the stone-faced assassin leader Daud, who received the same blessing of shadowy powers from the mysterious Outsider. The Outsider himself is perhaps Dishonored's greatest enigma to mold future stories around, but they don't have to involve Dunwall—I'd kill (not really, I'm a Low Chaos kind of guy) for a visit to other locations in the Empire of Isles beyond Gristol, particularly Corvo's home-island of Serkonos.
