Thief: The Dark Project Description:
As Garrett, a cynical and world-weary master thief, you must make use of stealth and intellect to complete your missions. You live in an ancient city of a fictional past where magic and primitive technology coexist uneasily. Your victims are the city's corrupt and privileged nobility, whose wealth is at your disposal as long as their guards don't see you, at least not until it is too late.
A mysterious patron offers you a fortune if you can retrieve an enormous gemstone with a notorious reputation. But your efforts trigger a conflict between veiled powers who compete to pull your strings. You'll need all your strength and wits to discover the truth and escape from the web of intrigue and deception spun around you.
Garrett's adventures take you through moon-lit city streets, guarded mansions, secure prisons, blazing factories, haunted cathedrals, abandoned ruins, and other strange environments.
