The sequel to the SNES title in the series released on the Sony PlayStation. It differed from the rest of the series, as it was a Strategy/RPG, unlike the rest, all being Action/Shooter/Platform titles. After the release in 1999, the same game would be reprinted by the company Four Winds on August 30, 2001. This game was never released outside Japan either.

2050. Fossil fuels such as oil is being depleted, and a disturbing atmosphere hangs over the world. Under such circumstances, the European Asia Commonwealth and the Pacific Rim United States, the two super powers of the world, rushed into the lunar military base development. Tactical beam guns have been positioned on the moon, in order to answer to any attack on the colonies. With the many disputes over mining resources, weapon placement and space colonies taking place, heroes of the Pacific Rim United States man their AS 117 Assault Suits and take to the battle ground to settle this war once and for all.
