Play Nekketsu Kouha Kunio-kun - Bangai Rantou Hen (Japan) Online

Nekketsu Kouha Kunio-kun: Bangai Rantou Hen came out on the Game Boy in 1990 from Technos Japan Corp. It was part of that early wave of portable beat 'em ups, scaled down but still trying to capture the rowdy spirit of its bigger console and arcade cousins. You could tell they were working with limited hardware, but the personality came through in the chunky sprites and the straightforward, no frills action.

You control Kunio or one of his friends, moving screen by screen through urban settings, beating up gangs that get in your way. The main goal is to clear each area of enemies, using punches, kicks, and grapples like throws and slams. Fights are fast and messy; you’re often surrounded, so timing your attacks and using environmental hits—like slamming foes into objects—is key. It feels scrappy and immediate, like a street fight squeezed into your hands.
