Now that you have a sub, you can chase down the enemy sub that's carrying the Huge Materia - but there's a catch: You must do this in 10 Minutes or less.
Try to stay behind the RED enemy sub, because it's the one that's carrying the Huge Materia. It isn't necessary to stroy the Yellow sub, but they'l be trying their hardest to sink you.
Tip:
You can shoot as many as four torpedoes at a time. Try to lock onto your target and unload the whole group, which is normally enough to take out a Yellow sub.
If the enemy gets a lock on you, speed up and dive deep. This will normally shake the torpedoes off your tail.
Mines are the small polygons on top of the square columns. You can pass through the columns without taking damage, just don't go too high.
Tip:
Don't worry too much about mines. Unless you're at full speed, you'll have plenty of time to react and adjust your course. Be careful when you enter the snoar screen, that you don't accidentally run into a nearby mine.
Use your sonar often to prepare you for what lies ahead. Plus, you can use snoar to help relocate the RED submarine if you lose track of it.
When you win the battle, you receive the Shinra Sub as a vehicle for the rest of the game. Althrough the submarine has limited range and can't pass through shallow water, you can use i tto check out the ocean floor and any underwater caves. You can dock at the small, rocky notches around the coast (like the one next to Junon).
The team picks up a radio signal declaring that Shinra is about to ship out another Huge Materia from the Junon Airport. Park the sub and get up there quickly.
The team arrives just in time to see the Materia leave by way of plane. The team needs to intercept the Huge Materia at Rocket Town. Get back to Highwind and get moving!
