Hokuto no Ken 3: Shinseiki Souzou: Seiken Retsuden (北斗の拳3 新世紀創造 凄拳列伝) is the third Hokuto no Ken game released by Toei for the Famicom. Unlike previous installments, which are beat-em-ups, it is an RPG which focuses on the beginning of the manga up until the Asura arc.
AmaizumiUni, however, skips basically all of the story by exploiting a glitch.
Watch this run being played back on a real console.
