Deep Dive Haunt

The Green December is the newest submarine of the US Navy, a technological and engineering marvel and you are one of its officers. The bad new is, that some kind of emergency while you slept and now the Green December is stranded miles under the surface, with heavy damage and even heavier causalties. What can you do in this situation? And what even happened? I coded a small list of possible hauntings into the scenario and it will randomly pull one of those. When the story starts it will give you a number. This is the number of your haunt. If you want to check which haunt you got: I put the list in the comments.
