The galaxy is in deep peril: foul creatures from the evil Bydo
Empire have warped across space to invade and conquer our planet!
There is only one hope for victory. The Earth Defense League has
chosen you to pilot R-9, a nuclear-powered space fighter that can
cut through invading aliens faster than a light saber through
butter. Fly R-9 through 8 exciting levels of high-powered action.
Use your plasma gun to rip through armies of nasty creatures and
their deadly machines. And when the going gets really tough, pick
up Droid Units to make your ship even harder hitting!
