The game was written by a then 16 year-old Robert Jaeger, who made two versions of the game for Atari home computers.

The game has an excellent rope-based mechanic that makes it different and interesting to play.
Ninja Cop (also known as “Ninja Five-O”) on the Game Boy Advance is a brilliant side-scrolling action game, sort of like a cross between Shinobi and Bionic Commando. The main character is agile and deadly, and gets to swing all over the place, and you do feel like an actual ninja (and a cop) when you master the controls and start making progress.
A classic action combat game from Hudson Soft and Konami!
Note: although Ninja Cop was developed by a Japanese company, it was never released in Japan. For some reason. Bizarre.
