Earth’s last line of defense rests in your hands. Hostile forces swarm closer—blast them before they overrun the planet. Automated lasers strike enemies directly above your ship. Watch the crimson health meter at the top-left: every hit you take drains vitality and slashes your score based on damage sustained. Fine-tune the soundtrack and explosive sound effects in settings—or silence them completely. The invasion grows fiercer with each wave. Can you crush the entire armada before they break through?
