Thief Gold

Thief Gold is a first-person perspective stealth game. It was the first game to use light and sound gameplay mechanics – different surfaces cause varying noise. You can use sound to your advantage - it's not only your main source of information on how close your enemies are but you can use it to distract them, for example by throwing objects. With unscripted levels, and objectives and paths altered based on difficulty settings, Thief Gold can give you hours of non-repetitive gameplay.
