Late in the 22nd century, humanity has spread across the solar system, terraforming and colonizing every viable outpost. The process had an unintended cost: the Galaga, mutated nanites born from terraforming runoff, now swarm through space with a single drive — destruction. They are autonomous, numerous, and lethal. In addition to blasting the insectoid attackers in the series' trademark fashion, players must complete mission objectives: recovering life pods, activating water turbines, and more.
