Black Belt 
Sega Master System
Beat'em Up
 
The most life-like karate game ever to meet the video screen. It's a post nuclear war setting. And the bad guys seem to be getting the best of things. You use your Black Belt standing to try to restore order to a chaotic world. In each round you must battle an entire enemy corps as well as its leader. And in each round the backgrounds - as well as your opponent's fighting styles - continue to change. Use everything the masters have taught you to stop the violence and restore peace.
