Dishonored is set in Dunwall, an industrial whaling city where strange steampunk- inspired technology and otherworldly forces coexist in the shadows. You are the once-trusted bodyguard of the beloved Empress. Framed for her murder, you become an infamous assassin, known only by the disturbing mask that has become your calling card. In a time of uncertainty, when the city is besieged by plague and ruled by a corrupt government armed with industrial technologies, dark forces conspire to bestow upon you abilities beyond those of any common man – but at what cost? The truth behind your betrayal is as murky as the waters surrounding the city, and the life you once had is gone forever.

The Game of the Year Edition of Dishonored includes the full game as well as all of the game's official add-on content, including Dunwall City Trials, The Knife of Dunwall, The Brigmore Witches and Void Walker's Arsenal.
