■STORY
One day, a gargantuan alien spaceship invades and unleashes countless combat weapons upon Earth, demolishing human civilization in the blink of an eye. Although humans succeeded in developing special weapons that could deal an effective blow to the aliens, it was too late to revive their civilization.
To this day, however, the Earth has yet to fall silent despite its abandoned cities, for swarm weapons known as "CogrinaUnits," 12-meter-tall autonomous humanoid units, collect and operate the limited number of special weapons that remain, and continue to fight against the aliens, all for the sake of accomplishing the mission humanity entrusted them with....
■Simple yet varied missions with a wide range of fighting styles
