Running Battle — About this game
Fight through five stages to break M’s hold on the city. This side-view brawler combines punches, crouching attacks and jumping kicks with gaps that must be crossed. Clear the enemies blocking each section before moving on to its boss. Recovery items restore health, while temporary strength boosts and firearms change how you handle the next wave.
