Conker is a series of platform video games created and produced by Rare. It chronicles the events of Conker the Squirrel, an anthropomorphic red squirrel that made his debut as a playable character in Diddy Kong Racing. The Game Boy Color game is targeted at a family audience. Conker's Bad Fur Day was changed during its development to be based on graphic violence, profanity, and other adult material, which earned the game a Mature rating by the ESRB, with an advisory on its box. A graphically improved but censored version of Conker's Bad Fur Day, along with new multiplayer modes, was released as Conker: Live & Reloaded on June 21, 2005 in North America for the original Xbox. The uncensored Conker's Bad Fur Day was released on Rare Replay and Live & Reloaded has been made backward compatible with the Xbox One.
