Fist of the North Star (NES video game)
"Fist of the North Star" is a single-plane beat-'em-up in which the player (as Kenshiro) proceeds through the game by walking from left to right, using his martial arts of Hokuto Shinken to defeat enemies. Similarly to "Kung-Fu Master", jumping is performed by pressing the d-pad upwards instead of having a dedicated button, leaving the A and B buttons solely for attacks. To enter a door, the player must press the d-pad right while holding A and B simultaneously, which is a requirement to proceed through certain stages. In addition to the regular enemies, the player must also defeat sub-bosses and bosses to proceed in the game. Each boss in the game has a weak point that will result in massive damage if the player strikes it with the proper attack before hitting any other part of the body, along with a greater bonus after the stage is cleared.
