NieR: Automata's narrative unfolds across three distinct playthroughs. While the first two playthroughs share significant overlap, the third playthrough reveals a wealth of additional story content beyond the initial credits.
Although the game features three main playthroughs leading to multiple endings, some endings require playing as a specific character and completing particular actions. This guide details the three playable characters and the method for switching between them.
The core of NieR: Automata's story centers around 2B, 9S, and A2. 2B and 9S are partners, and their screen time varies depending on the playthrough. Each character possesses a unique combat style, offering diverse gameplay experiences even with identical plug-in chips. All three are playable, but character switching isn't always straightforward.
Character selection is restricted during the initial playthrough:
Completing a main ending unlocks Chapter Select mode, enabling character selection. Chapter Select allows revisiting any of the game's 17 chapters. Numbers displayed beside chapters indicate completed/incomplete side quests. If a character has associated numbers for a chapter, that chapter can be replayed as that character.
Note that later chapters, particularly in Playthrough 3, restrict character selection. While Chapter Select allows character changes, the player must navigate to story points where that character was originally playable. Saving before changing chapters ensures progress carries over, allowing for leveling up all three characters' shared levels.
