You had taken special permission to go to the old laboratory that has been left abandoned for so many years. The reason that you wanted to go there was to find all equipment that could be useful to you. You did manage to find so many things in the laboratory but as you approached the main door to leave the place you discovered that the main door was locked. Now, you are inside a place that is not visited by people and that means you cannot hope for anyone to come by to get you out. You will have to pick the clues and items to use them to solve the puzzles that you encounter as you try to get out of the laboratory.
