Conker prototype footage is notably sober
Conker's Bad Fur Day began life as a sequel to the soft and fluffy Conker's Pocket Tales. Half an hour of footage of the original prototype, Twelve Tales: Conker 64, give us a glimpse of a much less edgy effort - all chirrups and whistling and sunny days.
Rare shelved this project, and Conker's Bad Fur Day re-established the character as an alcoholic on a hangover adventure. The series has been largely neglected since then, although a remake called Conker: Live & Reloaded hit Xbox Live Arcade in 2005.
Fansite Rareminion got hold of the Twelve Tales footage below; it's quite different from the finished product.
Thanks, GameInformer.
