- The NOPE achievement/trophy and its corresponding image is a reference to YouTube Let's Players, among whom the Amnesia series has become quite popular.
- The Still Alive achievement/trophy and its corresponding image is a reference to VALVe's video game series Portal, and its main villain GLaDOS. The Justine expansion was part of an ARG leading up to the release of Portal 2, hence the trophy and the note.
- The Illuminatus achievement cannot be obtained in Hard Mode, as that mode will remove a large number of tinderboxes actually needed for the achievement.
- Most achievements are handled by a script or by finishing a quest (i.e. when a memento gets removed from the journal). As such, those achievements can be easily hacked. The tinderbox achievement doesn't track the items like the note achievements, meaning that if the player gets enough tinderboxes (even in a mod), they will get the achievement. This is also easily hacked.
