3D Gamers - Thief: Deadly Shadows:

In Thief: Deadly Shadows, gamers once again take on the role of Garrett, a master thief. Garrett is rarely seen, never caught and capable of breaking into the most ingeniously secured places. Garrett steals from the wealthy and gives to himself, making his living in the dark and foreboding City. Preferring to be left alone to ply his trade, prophecies of an impending Dark Age dictate a different plan for the thief. In Garrett's efforts to prevent this approaching Dark Age, he has inadvertently roused an ancient hidden evil. Without allies, Garrett finds himself standing alone between the City and the forces that would crush it.

Playing as Garrett, you must use your skills to sneak throughout the City into castles, mansions, prisons, cathedrals, dungeons, and museums, past armed guards, hired muscle, angry thugs, hideous monsters, and much worse. Garrett must steal the City's oldest treasures in order to stop the darkness foretold in the prophecies. You will have a wealth of thieves' tools at your disposal, including lock picks, a variety of special arrows, wall climbing gloves, and flash bombs.
