Flying against fate, an S-1 rebel tries to defect to our side. But can a desperate and divided World Federation welcome him with open arms? Is this young Marine Leigan an ally or a spy? Can his robot ship Baldios and our Blue Strike Force unite to defeat The Red Fighters? And will it even matter if the impending doom arrives ahead of schedule? It’s space war fought on the environmental front. The ultimate battle for survival.
