EscapeGame Lübeck: Prohibited Area

You are a group of stalkers who only a few days ago crossed the frontier to the prohibited area in the Red Forest of Chernobyl. You have learned only just now that this forest has been highly contaminated by radioactive fall-out, so you're looking for a safe hideout. Soon you discover a huge iron door of a blockhouse that's been left ajar. However once you've entered, the door closes with a loud bang. Without knowing it, you've ended up in a secret hiding place of another adventurer named "The Chemist", and now you're trapped. So it is vital to use the following 60 minutes to escape; if not, the special forces hunting you will get you, and they won't let any witness stay alive.
