Dishonored is a 2012 action-adventure game developed by Arkane Studios and published by Bethesda Softworks. Set in the fictional, plague-ridden industrial city of Dunwall, Dishonored follows the story of Corvo Attano, bodyguard to the Empress of the Isles. He is framed for her murder and forced to become an assassin, seeking revenge on those who conspired against him. Corvo is aided in his quest by the Loyalists—a resistance group fighting to reclaim Dunwall, and the Outsider—a powerful being who imbues Corvo with magical abilities. Several noted actors including Susan Sarandon, Brad Dourif, Carrie Fisher, Michael Madsen, John Slattery, Lena Headey and Chloë Grace Moretz provided voice work for the game.

The game is played from a first-person perspective and allows the player to undertake a series of missions in a variety of ways, with an emphasis on player choice. Missions can be completed through stealth, combat, or a combination of both. Exploring each level opens new paths and alternatives for accomplishing mission goals, and it is possible to complete all missions, eliminating all of Corvo's targets, in a non-lethal manner. The story and missions are changed in response to the player's violent actions or lack thereof. Magical abilities and equipment are designed to be combined to create new and varied effects.
