Achievements

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 is displayed.

Notes

• 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.
• There is a total of 178 unlockable secrets.
  • Afterbirth added 98 unlockable secrets for a total of 276.
    • Afterbirth+ added 63 unlockable secrets for a total of 339.
• Using a seed prevents the unlocking of achievements for that run.
  • Certain cosmetic and difficulty-increasing special seeds will still allow unlocks.
• Playing with any enabled mod prevents any achievements from being unlocked.
  • If you have beaten Mom's Heart at least once, achievements will no longer be locked.

Note: Although not technically an achievement, getting 1000000% for all 3 save files will result in the special 3,000,000%!!! graphic showing on the save file selection screen. Simple file manipulation (copying save files and renaming them) in the Steam Remote folder (or Afterbirth+ folder if steamcloud is set to 0) will work. An easy way to do this is to earn all achievements on one file, go to the other files, enter the stats screen, and press Alt + F2. This will sync Steam achievements with in-game unlocks and will therefore grant all achievements for that file.

One 1000000% save file	Two 1000000% save files	Three 1000000% save files

Trivia

• The 5 Nights at Mom's achievement is a reference to Five Nights at Freddy's.
