Fist of the North Star (北斗の拳 Hokuto no Ken?) is a 2D competitive fighting game produced by Sega and developed by Arc System Works, based on the manga series of the same name. It was originally released in 2005 as a coin-operated arcade game for the Atomiswave hardware. A PlayStation 2 port, retitled Hokuto no Ken: Shinpan no Sōsōsei Kengō Retsuden (北斗の拳 ～審判の双蒼星 拳豪列伝～?, roughly translated as Fist of the North Star: The Twin Blue Stars of Judgment - History of the Fist Masters), was released in Japan in March 2007. This version features a bonus DVD including an exclusive training mode ("Starter's Guide") and a documentary covering history of previous Hokuto no Ken titles for home consoles. The arcade version was officially distributed by Sega in North America, while the PS2 port was released only in Japan.
