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 specific character choices and actions. This guide details the three playable characters and the mechanics of switching between them.
The core of NieR: Automata's story centers around 2B, 9S, and A2. 2B and 9S are partners and, depending on playtime in each playthrough, will likely dominate screen time. Each character boasts a unique combat style, offering diverse gameplay experiences even with identical plug-in chips. While all three are playable, switching isn't always straightforward.
Character selection is restricted during the initial playthrough:
Completing a main ending unlocks Chapter Select mode, allowing character selection. This mode lets you revisit any of the game's 17 chapters. Numbers displayed next to chapters indicate completed/incomplete side quests. If a character shows numbers for a chapter, that chapter can be replayed as that character.
Note that later chapters, particularly in Playthrough 3, restrict character choices. Chapter Select allows character changes, but you'll need to navigate to story points where that character was originally playable. Saving before chapter changes ensures progress carries over, enabling leveling up all three characters' shared levels towards the maximum.
