Final Fantasy VII/Submarine hunt

The Submarine hunt minigame is a minigame that occurs when you first acquire your very own submarine in Disk 2. The game consists of piloting your submarine around a fairly small map, avoiding mines and torpedo fire from other submarines while trying to sink the red Shinra submarine with torpedoes, which is transporting the huge materia that the party is after. The minigame can be won very easily, as the Shinra sub starts out right in front of the player sub, and sinking it is just a matter of pressing the "Fire" button enough times.
