dishonored

A 2012 stealth action-adventure video game developed by Arkane Studios and published by Bethesda Softworks. It was released worldwide in October 2012 for Microsoft Windows, PlayStation 3, and Xbox 360. Set in the fictional, plague-ridden industrial city of Dunwall, Dishonored follows the story of Corvo Attano, bodyguard to the Empress of the Isles.

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.
