The universe is a crucible of endless war. Three forces—the spore-born Orcs, the evolutionary Shapeshifters, and the high-tech Red Children of Mars—are locked in a stalemate that tears galaxies apart. Each faction is desperate for the singular dominance required to claim the universe as their own. Will you be the commander that breaks the deadlock, or just another causality of the endless front lines?
