This is fast and furious. Submarines from the enemy naval fleet have heard of your reputation as an excellent Navy Commander; and they are out to destroy both your reputation and you. They will do everything they can to destroy you; they want to blow you out of the ocean. You have to work fast, fire your torpedos and sink them first. Fire all tubes!
