Psyvariar 3

After the fall of ETA at the conclusion of Psyvariar 2, a faction of Psyvariars declared Earth worth saving and established GUIS to resume the original mission: reclaim and colonize the planet. Decades passed. The colony thrived. Then Gluon particles appeared in the atmosphere—the signature of alien presence—and the skies filled with a terror the colony recognized from before. Earth is under attack again, and a new generation of Psyvariars must rise to defend it. Psyvariar 3 is a vertical shoot-'em-up continuing the series after a long hiatus.
