The game format is mostly unchanged from the previous game (horizontally oriented and forward scrolling). Soon enough two young pilots volunteered for the mission. Thus, the development code Fire LEO-04 "Rynex" was given an emergency order to scramble. The Federation Army, with no time to spare, decided to inject all of their efforts in the development of the next generation of their ultra-high performance fighter aircraft which was under development. As a result all of the Federation's operations failed. However, the Vios forces had used this time to strengthen its forces, creating new weapons one after another which were unlike anything seen in the past. The Federation Army attempts to launch an attack against the forces hiding in the planet Aquaria. Considering this, the Galactic Federation mobilizes all of its power and embarks on a search for Vios. It was the existence of the subsystem " Vios", which could be called the heart of Khaos. In the last two years the Federation collected information in anticipation of the nightmare's return.

From the Thunder Force III record file-Īlthough it was a strategy that seemed reckless, fortunately they were so successful that our nemesis, the ORN emperor "Khaos", was overthrown. The Galactic Federation, which was in danger of extinction, issued a final command to the highly mobile fighter Styx and its two brave pilots to challenge the final battle.

The battle between the Galactic Federation and the ORN Empire was about to reach its 100th year, with the overwhelming superiority of the Imperial Army.
