Colantonio, on another similarity between Dishonored and Arx Fatalis:

"Most of the characters, specifically the assassination targets, you can actually [choose to] kill them or not. You can find other ways to eliminate them from the game. And the fact that you can do that, I think it's similar to Arx Fatalis. There were moments where, like—people did not want to kill the troll [in Arx Fatalis]. It was his birthday, and he looked nice, but he was, in a sense, a monster, and you needed something that he has. And so those interesting dilemmas that players will experience sometimes is something that I think we also have in Dishonored."
