S.S. Mission — About this game

S.S. Mission sends a helicopter through steadily scrolling waves of alien craft. The starting laser can be strengthened by collecting helicopter-shaped power-ups, while a separate limited bomb attack provides a way through a dangerous screen. Each stage ends at a larger enemy that must be defeated before the mission continues. The combination of weapon growth, bomb conservation and avoiding direct contact with hostile craft gives each new wave a different immediate priority.
