HOW ABOUT SPACEJACK A UFO AND TURN ALIEN TECH AGAINST THEM!
Take control, power up, and push back waves of space aliens in a fast, stage-based arcade fight for Earth. Blast through 49 stages of intensifying action as threats stack up and the sky gets meaner.
Drop a black hole to pull enemies into a vortex, nuke ’em back to the Stone Age, or flip the odds with slow-mo and invincibility when things get out of hand.
Health boosts, speed boosts, and weapon upgrades keep you evolving, while Swarm Time and Asteroid Alerts force you to adapt on the fly. Save the planet—one wave at a time.
