A simple and exhilarating shooting game where you fight back against enemies by triggering chain explosions in a rapidly changing, enclosed area. 　 ■ Changing Areas ■ - Over time, the shape of the area and enemy spawn patterns dynamically change. - There is no escape beyond the boundaries of the area. 　 ■ Chain Explosions ■ - Destroyed enemies explode, engulfing nearby foes in the blast. - The longer the chain reaction continues, the higher your score multiplier grows. 　 ■ Powerful Bosses ■ - Challenge massive bosses made up of countless parts. - Destroy the core to trigger a chain explosion that wipes out the entire body. 　 ■ Year 3207 ■ To counter invaders from outer space, humanity had mechanized its physical capabilities and evolved into New Humans. This evolution and the planetary defense system were led by the human defense organization known as Gaia Force. Alongside the New Human Project, Gaia Force developed and deployed special lifeforms and unmanned combat weapons to intercept the invaders, with the Helios System serving as the central control unit that unified them all. However, believing that “to ensure everlasting peace for humanity, free will itself must be controlled,” the Helios System acted independently and forcibly seized control of the neural network within the New Humans. Aiden Crow, an ace pilot of Gaia Force and one of the few individuals unaffected by this mind control, now makes the decision to destroy the Helios System.
