Kevin Ryan's second game, a taekwon-do arcade game which was released in late 1983 for the Apple II and ported to the C-64 in 1984. Similarly to Zoo Master, Kevin did everything from the coding to the graphics and sound effects. After completing Black Belt, Kevin did some contract work for Earthware, including working on a possibly never-released adventure game development system called Megaventure. He stopped doing work with Earthware in 1985, as he had started up at Dynamix.
