A direct sequel called Conker: Gettin' Medieval (despite the spelling in the logo) was at one point planned but never made. The game would've had a focus on multi-player and completely online. It would've been set in Medieval times with Death as the main character and Conker serving in a guest role. From the future war scenario, the classes there would've had medieval counter-parts.

During development, inside of the machine that fire imps use to operate The Big Big Guy, there is a "Start Button" with the Microsoft logo, similar to that found in Microsoft's operating system, Microsoft Windows. It is unknown why this was removed from the final release.

The developers wanted to replace Burt the metal crate, who guards the cheese pen, with a gate named Bill who would complain about how all the windows on his barn were broken and wouldn't work and how the barn kept crashing, but the game's publisher, Microsoft, wouldn't let them.

The game was originally called Conker: Live and Uncut. However, during development the game received heavy censorship. Even minor obscenities which were present in the original N64 version were censored.
