Thief: Deadly Shadows is a first-person and third-person 'sneaker', similar in gameplay to the previous games in the series. The player takes the role of Garrett, an independent master thief who aims to steal his way through the City, using stealth, devices and weapons, in order to complete objectives and make profits on the side. The player may steal from or mug innocents for loot, and avoid, distract, attack or knock out guards.
