The machine room in this big building is a place where no one is allowed to enter with permission. This is something that everyone knows and so no sign board has been put up with this warning. You being new to the place did not know about this and obviously you did not see any warning anywhere. You have entered the machine room and you are trapped in there automatically. You will have to get out of the machine room without wasting any time. It will be a very challenging task for you. Yes, there will be items and clues that you can find and use but nevertheless, it will not be easy.
