Thief: The Dark Project, or simply Thief, is a stealth-based first-person computer game and the first game in the Thief series. The game was developed by Looking Glass Studios and published by Eidos Interactive in 1998 for Windows. Set in a Medieval steampunk fantasy world, Thief casts the player as a professional thief named Garrett. Unlike most first-person games at the time, the development goal of Thief was to create a "first-person sneaker", where gameplay is based on the concept of avoiding combat.
Thief is played in the typical mouselook and keyboard control scheme for first person games. In addition to the usual health indicator and item displays at the bottom of the screen Thief has a visibility indicator known as the 'light gem', informing players of how well lit they are at any time.
When the light gem is at its darkest Garrett/the player is practically invisible and enemies won't know he is there unless they bump into him or are otherwise alerted. Speed of movement, standing or crouching and holding the different weapons all affect how noticeable Garrett is.

GLITCHES
Unlimited arrows
Go to the Haunted Cathedral. Go to the pedestal where you are supposed to light the torches with fire arrows. Go through the passage that opens up, then go inside the building. Bring a piece of a statue with you. Once you are in there, throw the piece on the very edge of one of the tiles (the ones that trigger arrows when stepped on). Note: There might be only one tile that works. If done correctly, arrows will start shooting out of the wall and get stuck in a wooden pillar. You can collect as many arrows as desired. The arrows will not stop until you take piece of the statue off the tile.
