For tips and strategies on completing achievements, see achievement tips.

Achievements are unlocked for players after completing challenges, reaching certain milestones, achieving hidden goals, or unlocking certain items. In the PC version, every Steam achievement exactly corresponds to one secret in-game, whereas only a handful of secrets are represented by PSN trophies in the Playstation version of the game.

If you are unable to unlock achievements, a small icon of a crossed-out trophy Disables achievements will be displayed below your keys counter. Conditions which can disable the ability to unlock achievements include:

  • Using a pre-determined seed. Added in Afterbirth Certain cosmetic and difficulty-increasing special seeds will still allow unlocks.
  • Added in Afterbirth † Playing with any enabled mod (unless you have beaten Mom).
  • Added in Afterbirth † During Victory Laps.

Rebirth has a total of 178 unlockable secrets. Added in Afterbirth Afterbirth added 98 new secrets, for a total of 276. Added in Afterbirth † Afterbirth † added 63 new secrets, for a total of 339. Added in Afterbirth † Booster Pack #5 added 64 new secrets, for a total of 403.

At the stats screen, pressing Alt + F2 will sync your unlocks with your steam achievements. Should you have steam achievements for secrets you haven't unlocked ingame, they will be unlocked by doing this.

Trivia

  • Each achievement is color-coded based on the requirements for unlocking their respective secrets:
  •   Although not technically an achievement, getting 1000000% for all 3 save files will result in a special 3,000,000%!!! graphic on the save file selection screen.
  •   The 5 Nights at Mom's achievement is a reference to Five Nights at Freddy's.
  •   The Mr. Resetter achievement may be a reference to Mr. Resetti from the Animal Crossing series.
  •   The Something Wicked This Way Comes quote is most likely a reference to the same quote from one of the witches from Shakespeare's play "Macbeth."
  •   Afterbirth+'s Booster Pack #5 added 64 secrets. Interestingly, this is a single secret more than Afterbirth+'s original count of 63 secrets. Thus, this update more than doubled the amount of secrets added to the game.

 PS4    Achievements 340-348 don't exist in the PS4 version, resulting in the content already being "unlocked" even on new save files.
