Play Hokuto no Ken - Seizetsu Juuban Shoubu (Japan) Online

Hokuto no Ken: Seizetsu Juuban Shoubu came out for the Game Boy in 1990, developed by Shouei and published by Toei Animation. It was one of those early portable adaptations that tried to squeeze a big arcade-style brawler onto a small screen, back when developers were still figuring out how to make action games work on monochrome hardware. You don't get much story setup; it's just you as Kenshiro, walking to the right and beating up thugs in a post-apocalyptic wasteland.

You control Kenshiro through side-scrolling stages, punching and kicking your way through waves of enemies. The main goal is to reach the end of each level and defeat the boss waiting there. Signature mechanics include using special moves by entering directional inputs, like the iconic Hokuto Hyakuretsu Ken rapid punches, and timing your attacks to hit pressure points for instant kills. The pacing is deliberate, almost methodical; you can't just button mash. Enemies take a few hits to go down, and mistiming a special move leaves you open. It feels stiff by today's standards, but landing a finishing move and watching an enemy explode remains deeply satisfying.
