Nuts & Bolts is an action and platform game in Rare's Banjo-Kazooie series, first announced at the X06 Media Briefing. It is the fifth game in the franchise to be released and takes place eight years after Banjo-Tooie. It is also the first game in the series released for a console unaffiliated with Nintendo, as it is exclusive to the Xbox 360. The game was released on November 11, 2008 in North America, November 14, 2008 in Europe, November 20, 2008 in Australia, and December 11, 2008 in Japan.
Eight years have passed since Banjo and Kazooie defeated the witch Gruntilda and destroyed her body. While Banjo and Kazooie are eating pizza, playing video games and listening to the radio, they discover Gruntilda's detached head returning to Spiral Mountain. They are about to fight when they are stopped by Lord of Games (L.O.G.). He attempts to settle the conflict between the two by devising a series of worlds and challenges. He uses his powers to give Gruntilda an artificial body and to restore the duo's physical fitness, but not their moves from previous games.
L.O.G. transports the other characters to Showdown Town, his headquarters, and starts the contest. The winner would be set to own Spiral Mountain; the loser must endure eternal hardship at L.O.G.'s video game factory. While Banjo and Kazooie seek to win by completing the challenges, Gruntilda uses her powers and abilities to try to stop the duo. An army of mechanical Gruntbots also assist the witch in her goal. The game ends with Gruntilda and Banjo attempting to face a final duel when L.O.G. once again comes in to stop them. After L.O.G. sends Gruntilda off to toil away at his video game factory, he rewards Banjo and Kazooie by restoring their moves and giving them the deeds to Spiral Mountain. Gruntilda vows that bringing her to the factory was a mistake and that she will make her own video game.
