Make a raid deep into alien force positions to eliminate the threat for your homeworld. You'll encounter lots of different alien ships, upgrade your weaponry with extra-weapons, blow up enemy barriers and defeat powerful bosses. Lots of special effects, unique tactics for each level, nice music and sound FX, Worldwide Hall of Fame and much more.

It's not easy to survive under the alien sky when there's always someone to burst you with his weaponry or overcome with his tactics. However you have to. Cause you and your ultramodern space-fighter are the only chance to prevent alien invasion which is almost ready to start, turning your homeworld into ruins.
