Conker's Bad Fur Day is a 2001 platform game developed and published by Rare for the Nintendo 64. The game follows Conker, a greedy, hard-drinking red squirrel who must return home to his girlfriend after binge drinking. Most of the game requires the player to complete a linear sequence of challenges that involve jumping over obstacles, solving puzzles, and fighting enemies. A multiplayer mode in which up to four players can compete against each other in seven different game types is also included. It is the second installment in the Conker series, after Conker’s Pocket Tales.

A platformer is a sub-genre of action video games in which the core objective is to move the player character between points in an environment. Platform games are characterized by levels with uneven terrain and suspended platforms of varying height that require jumping and climbing to traverse. Other acrobatic maneuvers may factor into the gameplay, such as swinging from vines or grappling hooks, jumping off walls, gliding through the air, or bouncing from springboards or trampolines.
