60 Fathoms Below

You have just stepped foot into the drawing room of a steam powered submarine, the Meridian. All the doors have locked behind you and you are now sinking to the bottom of the ocean. This submarine is only rated for 60 fathoms. Sinking at one fathom per minute you are doomed to crush if you don’t get out of here and restart the engine. Wait, did you hear that noise...creaking?? You'd better hurry up!
