Carrie Fisher, who recently passed away at age 60, had a minor role in Dishonored.
According to Glixel, Fisher recorded several lines for developer Arkane Studios’ stealth game and her work is well hidden. You have to kill a certain propaganda officer during the “Return to the Tower” mission.
Afterwards, late in the game, you have to pay close attention to spot her voice coming over the public address system in Dunwall, Dishonored’s main setting.
Fisher tells people not to “interfere with the regular transfer of deceased persons to disposal centers in the Flooded District” or that “any disturbance in the region of Dunwall Tower this evening has been the result of a previously scheduled training exercise.”
