An unofficial expansion pack to Thief II: The Metal Age with features similar to those in retail Looking Glass games: complex level design, a lengthy campaign (consisting of thirteen long missions), pre-rendered introduction and ending sequences, original music, new voice acting, original artwork, and animated mission briefings.

Thirteen full-length missions take the action through city streets and rooftops, ancient tombs, hotels, museums, cathedrals and more in a gripping tale of vengeance and deception. Hundreds of new models, textures and sounds: 3000 lines of new dialogue. Four cutscenes and twelve new briefings in the original Thief style. Ten new weapons and tools provide the means to evade, outwit, and out-fight your opponents, as well as bringing unprecedented levels of emergent gameplay to the Thief series.
