When you first look at Ninja Five-O, you might think it's a silly simple game. However, when you first pop it in and play, you will have a change of heart. Owing a big debt to the Shinobi games of the 16-bit era and the Ninja Gaiden series, you play a ninja cop taking on enemy ninjas and terrorists. Gameplay wise the game is very difficult and challenging, which is perfect for fans of the aforementioned games. The graphics are typical 2-D side scroller fare, but that's not such a bad thing with some nicely animated characters and textures. All in all, Ninja Five-O is a great action game that those who yearn for the days of Shinobi and Ninja Gaiden will love. This is the game that THQ's Revenge of Shinobi for the GBA should have been.
