Alarm everyone, this submarine is sinking! Something happened, and now the vessel is rapidly going dysfunctional, threatening everyone on board. At such a huge depth, there is really no hope someone will come to the rescue, so you have to take care of your own survival. Your task is to make sure your character is stocked up on oxygen, water and food, and all the things needed to stay alive until you figure out a way to contact the land and get a rescue team down to save you. Good luck!
