View source for Achievements

''For tips and strategies on completing achievements, see [[achievement tip]]s.''

'''Achievements''' are unlocked for players after completing [[challenge]]s, reaching certain [[completion mark|milestones]], achieving hidden goals, or unlocking certain [[item]]s. 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 {{no unlocks}} will be displayed below your [[key]]s counter. Conditions which can disable the ability to unlock achievements include:
* Using a pre-determined [[seed]]. {{dlc|a}} Certain cosmetic and difficulty-increasing [[seed|special seeds]] will still allow unlocks.
* {{dlc|a+}} Playing with any enabled [[mod]] (unless you have beaten [[Mom]]).
* {{dlc|a+}} During [[Victory Lap]]s.

Rebirth has a total of 178 unlockable secrets. {{dlc|a}} [[Afterbirth]] added 98 new secrets, for a total of 276. {{dlc|a+}} [[Afterbirth †]] added 63 new secrets, for a total of 339. {{dlc|a+}} [[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.

* {{dlc|a+}} Although not technically an achievement, getting 1000000% for all 3 save files will result in a special 3,000,000%!!! [[Savefile Images|graphic on the save file]] selection screen.
* {{dlc|a+}} The 5 Nights at Mom's achievement is a reference to [[wikipedia:Five Nights at Freddy's (series)|Five Nights at Freddy's]].
* {{dlc|a+}} The Mr. Resetter achievement may be a reference to Mr. Resetti from the [[wikipedia:Animal Crossing|Animal Crossing]] series.
* {{dlc|a+}} 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."
* {{dlc|a+}} 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.
* {{plat|PS4}} {{dlc|a+}} Achievements 340-348 don't exist in the PS4 version, resulting in the content already being "unlocked" even on new save files.
