Nier: Automata has 26 different endings. Some require a lot of work, getting to the very end of the game and making a certain choice, while others are easy and just require failing certain missions. Keep in mind that beating Nier: Automata for the first time is not known as the end of the game, it only results in one ending and then the player can begin a second playthrough with all their gear and levels intact.

Obtaining all the endings without a guide is near impossible, as they can get quite specific. If attempting to get all the endings, remember to keep a lot of save files. Certain endings, such as Z and F are known as «bad ends» and thus take the player to the title screen without saving their game.
Endings A through E are known as the main endings of the game and require completing the main story at least three times. Note that ending E is the ending to complete last of all, as it can delete every game save if the player chooses to become one of the helpers. Save it for last, when all else that is wanted to be done is done.
These are the endings that are easy to miss, as they can occur by failing missions, killings friendly NPCs, and making certain choices in side quests.
NieR: Automata is now available on PC, PS4, and Xbox One.
