GoldenEye 007 · Nintendo 64 · 1997 · Unlockable
Effect: Unlocks a cheat menu with options such as invincibility, all weapons, paintball mode, and the notorious DK Mode.
Rare refused to hand players a simple button sequence. Instead, GoldenEye 007 locked its cheats behind punishing speedrun challenges — to earn invincibility you had to clear Facility in 2:05 on the hardest difficulty; other toggles demanded near-flawless runs of Dam, Aztec, and Cradle. The most infamous unlock, DK Mode, swelled every character’s head and arms to Donkey Kong proportions, an in-house joke referencing Rare’s own Donkey Kong Country pedigree. Because the time trials doubled as an eternal skill ladder, GoldenEye became one of the earliest console games with a thriving speedrun community, chasing the very targets Rare had set as cheat requirements decades before online leaderboards existed.
