Invasion From Outer Space is a fast-paced game of fiendish Martians, Big Top Heroes, and SciFi Movie Action. Players take on the role of either the Carnival Heroes, using their special talents and working together to fight off the Martian Invasion; or as the invaders themselves, waves of Martian Soldiers and Flying Saucerss, blasting Humans with Ray Guns and unleashing their vile alien technologies upon the Earth.
