Flying Warriors is a 1991 action/fighting video game developed by Culture Brain and published by Culture Brain USA exclusively for the NES in North America in February 1991. It is a mixture of two Family Computer video games in the Hiryū no Ken franchise: Hiryu no Ken II: Dragon no Tsubasa and Hiryu no Ken III: 5 Nin no Ryuu Senshi. It implements ideas and elements from both games, thus making it hard to tell which of the two is officially its Japanese version. The first installment of the Hiryū no Ken series had already been released in North America as Flying Dragon: The Secret Scroll, with virtually no modification.
