The Father of all "stealth" games and the whole genre. Full, quality and detailed walkthrough of the PC game "Thief 1: The Dark Project" (Gold edition, released in 1999), Mission 13 - Return to the Cathedral . The game played by me on Extreme difficulty with flawless free flow completion of the missions without dying or reloading. All the loot was collected on each mission. The documents\scrolls\books were opened for a very short time, so use pause for reading. All the scenario scenes are included in the video, from the intro of the game till the credits at the end, hence the watchers can understand the storyline of the game. Enjoy watching\rating\commenting the video. Have a nice day.
