At the time, Nintendo was an up-and-coming arcade developer that made a handful of games, such as an unusual version of Space Invaders called Space Fever. Radar Scope, as well as another game called Space Firebird, were attempts to go beyond Invaders, and Radar Scope successful for a time. Meanwhile, Nintendo opened up a new branch in the United States called Nintendo of America, and the president of the company ordered a large shipment of Scopes, hoping for a similar result. Unfortunately, there were large delays getting the games made and shipped to New York, missing the window of opportunity. Radar Scope did not do well, and Space Firebird ended up more popular in the States.
