Development for both platforms started simultaneously. It was released for Microsoft Windows and the Xbox in 2004, on May 25 in North America, and on June 11 in Europe.

The game also introduced an ability to switch between first and third person views, and to flatten against walls. While previous games sent Garrett straight from mission to mission, Thief: Deadly Shadows allows him to walk the City streets between missions where he can steal from passersby, spy on the townspeoples' daily lives, and search for sidequests in addition to major story missions. One of the game's major new features was the ability to explore The City. It is the third game in the Thief series, and a major departure from the first two games in the series, different in both appearance and gameplay.

It is set in a fantasy/steampunk world resembling a cross between the Late Middle Ages and the Victorian era, with more advanced technologies interspersed. Thief: Deadly Shadows is a stealth video game where the player takes the role of Garrett, a master thief.
