Radar Scope is an arcade game manufactured by Nintendo. The game was an unexpected failure. Many Radar Scope cabinets were converted into Donkey Kong.
The Earth is under attack by the Gamma Riders, a group of aliens. As the captain of one of Earth's space ports, you must defeat them.
The Gamma Raiders hover at the top of the screen. They are to far away until they reach the blue grid. As the game progresses, more aliens swoop down at a time and, occasionally, a heavily damaged vehicle will try to crash into you.
