Thief II: The Metal Age is a first-person stealth game developed by Looking Glass Studios and released by Eidos Interactive in 2000. It is the sequel to Thief: The Dark Project. The game is set in and around a steampunk metropolis called the City.

Looking Glass Studios released the sequel to Thief in 2000. Utilizing the same DARK engine that powered the original Thief, Thief II had an almost identical look and feel, with only minor graphical and programming improvements, such as flowing lava. The basic gameplay was also fundamentally similar to the original Thief, but many new elements had been added, including technological gadgets such as a remote eye camera. Other changes include an increase in the number of A.I. behaviors, and the addition of female guards and soldiers.

Responding to criticisms of the original Thief, in that more time was spent on combat than actually living up to the title of the game, the missions in Thief II were designed much more around typical thief-like behavior, and much of the game is spent robbing the rich denizens of the City rather than battling monsters. In fact, the player encounters almost none of the monsters from the original Thief except for burrick (dinosaur-like creatures) heads mounted as trophies in some of the mansions, a few zombies, undead and ghostly apparitions. The designers stated that unlike the original Thief where levels were developed to suit the plot, in Thief II levels were designed first and making the plot work with them was somewhat of a retrofit.
