While Rock Lee and Naruto are the only playable characters in Naruto SD Powerful Shippuden, a bunch of other ninja are available as support characters. Namco Bandai announced Yamato, Gaara, Shikamaru, Ino, and Choji (who turns into a giant pink ball?) are in the Nintendo 3DS game.
Mega Man 9 developer Inti Creates is behind Naruto SD Powerful Shippuden, which piqued our interest. They also make a bunch of Shin-Chan platformers for Namco Bandai. We’ll get a better idea of how Naruto SD Shippuden plays on November 14 when Namco Bandai releases a demo in Japan. The game has not officially been announced for the West, but signs point to it coming over perhaps as a digital release.
