The 'Unlocks' category refers to special items that you can get in Outertale (but not Undertale) that can either be dependent or independent of your save file.

Independent of save file

  • Constellation Cards: The primary currency of unlocking hidden features of the fangame.
  • The Bedtime Story: A set of two cutscenes that truly finish the Save Everyone Route.
  • The Save Everyone Route: The ending where you sacrifice yourself so Asriel can live.
