Welcome to prison. You are being held in the storage room of what used to be an office building or something but is now a Combine facility! You will need to figure out a way to get out of the room in which you are being kept. That guard won't hurt you unless you touch the crowbar. You need to be weary at all times and ALWAYS be ready for combat!
