Saw

You regain consciousness huddled together in a dim back room of a multi-chamber underground cellar system. You look around... no windows, only a door, a monitor, and a faintly flickering wall lamp. You rush to the door, but it’s locked, and then it hits you... this is the end... At that moment the monitor turns on, and a strange masked figure, speaking in a distorted voice, delivers the following message to you: "Hello! I have a little game for you! To survive, you’ll have to solve numerous tasks. Countless doors, locks and chains stand between you and the final exit that means freedom. Room by room you must find the key to get out. Everywhere you’ll face real, physical puzzles that operate on logical principles and demand teamwork; if you solve them successfully you move on. If you don’t, then... A countdown mounted on the wall shows the rapidly dwindling time. You have 60 minutes to escape this cellar system full of dexterity and logic challenges. There is only one way out, and you must find it. Let the game begin!"
