Thief: The Dark Project Cheats

In the Lost City level, buy the speed potion before starting the mission. When you enter the tunnel past the big waterfall, instead of going left to the library, go right. Follow the tunnel and kill the baby spiders. When you get to the opening you will be looking at the talisman in the tower (Garret says ''So this is the Lost City...) Rope arrow one of the rafters. Drink the speed potion, then get a running start straight towards the opening, and jump to grab the rope (it may take a few tries). Once you get across, just climp the rope, jump through the window, and the Talisman is yours!! This may also work on Thief Gold, but I haven't tested it.
