The scene in which the Japanese captain uses a network of tsunami detecting buoys to try to reach the enemy fire on ordering certain coordinates on a grid (Alpha 11, Bravo 44, etc ...) directly refers to the way you play the starting in the real game, had only missed the head of the alien fleet shout "water", "touched!" or "sunk", depending on where the rockets fall.
