You're in the Martian sky, you need to land, but there's something in your way.....a City. Use your skill and judgment to fire lasers and destroy the offending obstruction chunk by chunk.
Take out the buildings by pressing any key to drop lasers from your UFO. If your UFO hits a building it??s game over. Your goal is to destroy the entire city to enable your Spaceship to land. Level the city in a quick time and earn yourself bonus points.
