While playing the "NieR: Automata" game demo, an Easter egg ending can be triggered by pressing a single button. Basically, the players will just need to remove an item in their inventory screen.
According to Game Rant, the unique way to get a game over screen for "NieR: Automata" is to remove a computer chip from their inventory. Doing so will fade the screen to black before getting back to the menu screen.
It is not just any computer chip, however, as it is the OS chip for the protagonist android in the game. Removing the chip is essentially removing the character's brain, which kills the character.
Curious gamers still went on with the OS chip removal, just to test whether or not it really does result in death. With that, the Easter Egg was discovered, but the bigger mystery is the fact that it took a week before anyone made the announcement.
However, it is understandable that an accidental robotic suicide can be made as the OS chip is only one among the hordes of items the player can hold in their inventory. After all, some of the items can give a boost to a certain skill or change the passive abilities players possess while players roam the game world.
Furthermore, according to iTechPost, there are rumors that the computer chip will play a bigger role in the future. Basically, in the full game, it could give players an option to self-destruct, causing the character to explode while dealing massive amounts of damage to surrounding enemies.
This has not been proven yet, though. After all, the game developers did nothing to confirm nor deny anything about the future of the option. Nevertheless, it does not discourage players to speculate that the chip will play a big part once "NieR: Automata" is released on Feb. 23, 2017.
