Junon Underwater Reactor
Overview
The Junon Underwater Reactor is a hidden Shinra facility beneath the military port. The route passes through service corridors, elevators, glass tunnels, submarine docks, and the reactor complex itself. The party fights Shinra troops, machines, and Carry Armor while attempting to intercept a Huge Materia shipment. The facility also introduces submarine combat and leads directly to the underwater world map. Most of the reactor area becomes inaccessible after the mission.
