Get the True Ending
If you don’t know by now, NieR: Automata features multiple endings, and you’re going to want to replay the game a few times in order to get the full story. If you’ve only beaten the game once, thinking that’s the end of it, go back to it again. Load up your cleared save file and work towards Ending B. Your second run will be very similar to your first, with a few differences here and there. However, once you get that second ending out of the way, the game changes drastically.
At the moment, we’ve discovered five proper endings to the story. Once you reach Ending E and see the credits roll, you’ll know you’ve gotten the complete experience.
