The Naruto: Clash of Ninja series, known in Japan as Naruto: Gekitō Ninja Taisen! (ナルト-激闘忍者大戦) is a series of 3D cel-shaded fighting games of the Naruto franchise. They are developed by Eighting and published by D3 Publisher and Tomy. Various instalments of the series have appeared on both Nintendo's GameCube and Wii. Four games are available for the GameCube and seven are available for the Wii. The first two GameCube instalments and the three games of the Revolution sub-series are available in the United States and in PAL regions. All other instalments have been released exclusively in Japan.
Each instalment of the series has had numerous methods of play with varying types of modes. New games have introduced additional modes that generally appear in subsequent games. The player directly controls a character taken from the Naruto series, and uses their unique abilities to battle and defeat an opponent. New games in the series include more of the Naruto plotline in a "story mode," and it generally stays true to the source material. As a result, the character selection increases with each instalment due to the inclusion of more of the Naruto plotline. With the newer games incorporating Naruto: Shippūden, the second part of the Naruto series, many of the characters have been substantially redesigned, and the playable cast has been correspondingly limited and increased depending on the story. Reactions to each instalment have been mixed, with many praising the simple and easy-to-learn fighting system, with others lambasting the fighting system and the lack of significant unlockable content.
