Defend the lower atmosphere. Clear the swarm. Survive the fleet.

Wave after wave of alien invaders descends from orbit. You command the last ground cannon. Move along your line, return fire, and wipe out every invader before the formation reaches the surface. Each cleared wave brings a faster, more aggressive swarm - and every fifth wave sends down a colossal boss craft.

You begin with 3 lives (maximum 5). Lose a life when a bomb hits your cannon. It is GAME OVER if your last life is lost or if the swarm descends to your line.
