The Space Invaders are back, and this time they're out to get even! Take control of a UFO and make those Earthlings pay by unleashing your fleet of heroic invaders against their puny tanks, fighter jets, and artillery--but watch out for the massive boss awaiting you at the end of each stage! Use your invaders' five attack types and the might of the mother ship to rack up high scores, then upload them via Nintendo Wi-Fi Connection and see where you stand in the global rankings!
