From the far reaches of Neptune, to the safe haven of Earth - battle your way across the universe in this exciting adventure based on the popular arcade game.

Suspense builds with every beat of thrilling and dramatic music - perhaps unlike any video game music you've ever heard before! To these compelling strains, you'll fend off unremitting waves of spiraling, swirling alien ships. Piloting your spacecraft in a circular flight pattern, blast these fiendish intruders with your rapid-fire lasers - before they vaporize you. And watch out for killer meteors and deadly satellites along the way!

Reach one planet and you'll have just enough time to catch your breath for the next-and more difficult-wave of enemy attacks that separates you from eventually reaching the sanctuary of Earth!
