Naruto: Clash of Ninja, released in Japan as Naruto: Gekitō Ninja Taisen! (NARUTO 激闘忍者大戦!), is a series of 3D cel-shaded fighting games based on the manga and anime series Naruto by Masashi Kishimoto. They are developed by Eighting and published by D3 Publisher and Tomy. The series began with four GameCube games, with the first two available internationally and the last two released exclusively in Japan, before splitting into two parallel Wii-exclusive follow-up series: the Gekitō Ninja Taisen EX tetralogy released exclusively in Japan and its international counterpart, the Clash of Ninja: Revolution trilogy. The two Wii series share the same gameplay mechanics, but differ with respect to content and characters, with the international Revolution series being based on a localized version of the Naruto anime series.[1] The first half of the original series and the entire Revolution trilogy are available in North America and Europe, (although the first Clash of Ninja wasn't released in the latter) the first two Revolution games are available in Australasia and all games in the series except the Revolution trilogy are available in Japan.
