Commander, the girls await your call. Are you ready for this epic journey? In the 119th year of the Old Euro Calendar, a mysterious catastrophe gave rise to crazed "Catastromechs" that swept through civilization. Survivors created new shelters and fused Catastromech cores with humans, creating powerful "Stellar Spirit" battle maidens. As Commander, lead these battle maidens to combat the Catastromechs, rebuild a new home called "Pax," and restore peace.
