The aliens are coming, and our traditional weapon systems are useless against their advanced technology. Humanity's last hope is to unveil the STAR GLAIVE, a prototype combat ship that can absorb and turn back the alien attacks.
Battle more than 30 boss ships by turning their own weapons against them. If that's not enough action, use the built-in boss editor to create challenges we couldn't dream of, then share them with friends or strangers and cackle in delight as they try to face your genius.
