In each game of the series, the player controls one of many characters directly based on their counterparts in the Naruto anime and manga. As in practically all fighting games, the player then pits their character against another character controlled by the game's AI or by another player, depending on the mode that the player is in. The objective of each game is to reduce the opponent's health to zero using basic attacks and special techniques unique to each character that are derived from the source material. For instance, Naruto Uzumaki can use his signature Shadow Clone Jutsu, (影分身の術, Kage Bunshin no Jutsu, English manga: "Art of the Shadow Doppelganger") and Rock Lee utilizes many of his Strong Fist style techniques.[3] Characters have available a chakra bar, which depletes upon the execution of a special technique. Each game in the series also possesses numerous modes that offer different styles of play. The game's story mode follows the plot from the anime and manga, with a versus mode pitting two players against each other also included. Each game in the series adds new modes, as well as incorporating new features into the game. Early games feature unlocking characters by using a Shop and obtaining money in fights. Most of the games feature an 'Omake' bonus section which contains music, sound effects, and character models. All games in both Wii series take advantage of the Wii Remote's versatility and motion controls, as well as the console's backwards compatibility, to provide multiple control schemes, allowing players to perform gestures to execute certain attacks with the Wii Remote and Nunchuk, or use traditional pad controls with the Wii Remote held sideways, the Classic Controller or the GameCube controller.[4]
