Dishonored

Dishonored is a 2012 stealth action-adventure video 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, Lena Headey and Chloë Grace Moretz provided voice work for the game.

Dishonored is an action-adventure game played from a first-person perspective with an emphasis on stealth action and the use of gadgets and the environment to eliminate opposing forces. The game world is a series of self-contained, mission-focused areas designed for multiple avenues of exploration in terms of in-game movement and powers. Between missions, the player is taken to a central hub called the Hound Pits pub where the player character Corvo can meet with his allies, receive mission briefings and alternate objectives, and convert recovered loot into new equipment and upgrades. In-game areas include loading docks, royal estates, poverty-stricken streets, and a bathhouse. The player can save their progress anywhere, and the game includes a checkpoint save system. Saving is disabled during combat. The game has four difficulty levels which modify the effectiveness of health and mana (magic) potions, and enemies’ awareness, damage delivered, and responsiveness. In the easy setting, health regeneration is possible.
