Unlockable Achievements[]


  • The first scenes in Ending 15 and Ending 17 show The Missing Poster pinned to a utility pole, with a silhouette of Isaac's mother who seems to be searching for Isaac in the background.
  • There are many puzzle pieces in total. Assembling all of the jigsaw puzzles and figuring out what they meant was initially designed to be a collaborative effort of the community. As such, Edmund and Tyrone had openly expressed disappointment towards the datamining.[citation needed]
  • The unlock pop-up of Missing Poster calls it "Lost Poster". Unknown if it's a mistake or a hint.
  • A chest always containing the Missing Poster will appear as a room clear reward from the Dogma room, although it is impossible to access it without the use of console commands.
