Thief: Gold

Thief: The Dark Project is a first-person immersive stealth game set in a noir medieval fantasy world where civilization and the supernatural are constantly in conflict. The player takes on the role of Garrett, an orphan who turns to thievery after a brief residence with the shadowy Keepers. Sneak through manorhouses, crypts, lost civilizations and beyond in this superb classic from the masterminds at Looking Glass Studios.

Thief: Gold is a re-release of this seminal classic, and includes three extra missions among other tweaks.
