Currently stuck on the bottom of the north sea after attempting to take on a battleship with a deck gun. Previous attempts to escape were futile and as we speak the damage control team struggle to fight against the ever growing tide of water as our U-boat turns into a swimming pool. My trusted sonar man which I nicknamed "sonar guy" was tragically killed. There are currently no men in the quarters as everyone is doing there bit to get home. Hull integrity is very low and much of our equipment is damaged and at this rate we are all going to drown, well that is if the water beats the air supply.

how to get out of this one?
