Thief is a series of stealth video games where the player takes the role of Garrett, a thief in a fantasy/steampunk world resembling a cross between the Late Middle Ages and the Victorian era, with more advanced technologies interspersed. The series consists of Thief: The Dark Project (1998), Thief II: The Metal Age (2000), Thief: Deadly Shadows (2004) and Thief 4 (TBA). An expanded version of Thief: The Dark Project, titled Thief Gold, was released in 1999 and features three extra maps and several bug fixes. Looking Glass Studios developed both The Dark Project and The Metal Age. After the studio went out of business in 2000, many former employees moved to Ion Storm Austin and began developing the long-anticipated third part of the series, Deadly Shadows. Eidos Montreal was subsequently given the reins for Thief 4, which is currently in early development stages.
