'I can see it. I can see it,' the pilot's voice crackles over the radio. 'It's metal and flat, like a big plate. It's moving incredibly fast! It's starting to glow. It's. .' They found pieces of the plane scattered across thirty miles of countryside. Are aliens invading the earth? Or are the mysterious pulsing lights shooting across the sky really meteors, weather balloons, airplanes, geese, clouds, comets, bright stars, or mirages? Are you sure? Now you can lead the search for flying saucers or invade the Earth in UFO. For the Alien player, the object is to land five of the eight available flying saucers on the Earth. The Earth player, using eight space rockets, must prevent this to win. Movement is along orbital paths around and toward the Earth. Combat is short and destructive. In addition, a Moon orbits the Earth (really!), from time to time with extremely unpleasant results for any ship caught in its path. The advanced game enjoys the same simple victory conditions as the basic game, but adds a few complications. The Earth player must now add the power of deduction to his playing abilities, as a host of true UFOs now share the skies with the real flying saucers. Countering this, the Earth player receives six space stations to help defend the planet. Basically, a pretty simple game with about equal blending of luck and skill. Good for an evening off from the wargames and excellent as an introductory game for friends and relatives.
