All the instructions are helpfully placed around the room on the walls, but you just have to use the controls to pick up and put down a flashlight then find 3 tokens to exit the room. the tokens being 2 on the one table in the room(you can pick up one in each hand), put them into their keyhole in the door and then turn around and the last one will be on the floor near you and once it is inside the keyhole the door will unlock and you will get the trophy.
