Fight your way through 50 waves of enemies in this classic arcade style shooter. Earn free ships for every 5,000 points you score. Rack up three extra ships and the score multiplier increases as you earn more points. Loose a ship, and the multiplier gets set back to one. Be careful because your spare are directly in the line of fire. Too many hits and they explode into a shower of bullets. Use them to clear the screen if things get too crazy.
