After training with an enigmatic organization known as the Keepers, Garrett leaves the order and returns to a life of theft on the streets of the City. Entering the underworld brings its own consequences, and he is not the only one seeking valuable loot.

Players hide in the shadows of a dark, savage city and sneak into old ruins, haunted cathedrals, and the mansions of the rich. Enemies can be dealt with quietly or in open combat.

The game offers a range of ways to reach your goal, but secrecy remains the best approach.
