Thief is a choice-driven stealth game. You take control of a thief called Garret as he steals his way through the game. With gameplay being choice-driven, it means players have a number of possible paths and approaches they can take to advance through levels. Players may use the environment to their advantage, as well as pickpocket characters. As Garrett attempts to steal in levels, guards and other non-player characters (if aware of his presence) will try to flush him out and kill him. Thief is an action-packed game and a fresh modern version of the well known classic game series of the same title.
