Three years and ten months after release, someone finally found Nier: Automata's final secret. It was announced by discoverer Lance McDonald today, then confirmed by series director Yoko Taro less than seven hours later. The confirmation of the final secret was also noted by the official Nier account. Spoilers follow, but frankly you'd literally have to delve into the game's code to discover this. Here's Yoko Taro's tweet, with McDonald's tweet embedded:
The final secret is a cheat code performed after killing the first boss. It's a complex series of attacks, rolls, and moves in the vein of classic cheats that must be done while standing in a specific spot. Once performed, the player is instantly transported to the "last" of the endings, of which the game has many, a decision that deletes the user's save and unlocks bonus game modes. To be clear, it's not an exploit, it's a cheat deliberately programmed into the game. Asked how he found it, Lance McDonald replied "hundreds of hours of reverse engineering."
