- Game Commentary: It can be accessed from the options at any time, and it plays it straight with the developers talking about "behind the scenes" stuff with Cry of Fear. However, starting with Chapter 2, some of the audio was edited so it's hard to hear without going into the game's files.
- Official Fan-Submitted Content: The Steam release comes with several community-helmed projects, the most notable probably being the "Memories" campaign since it also includes work by ruMpel.
- Throw It In!: Many ideas used for the game came from suggestions from others.
- The dead cat seen during Chapter 4's vent sequence is the same cat from the intro. The reason it's there is because the mod team hates cats, as stated in the commentary.
- The train escape sequence came about when the mod's developer told some of his college friends that he was working on a train sequence and wanted some ideas on how to end it. The scene in the final version was what was suggested.
- What Could Have Been:
- The Developer's Commentary reveals that the camera sequence in the first part of the game is a leftover from the original idea for the mod, where Simon would have killed his mother and, in his psychosis, went around taking photos of her. The idea was eventually scrapped.
- As mentioned under Dummied Out, several other weapons were planned but ultimately not included. The Taurus PT92 pistol was replaced with the Glock, while the S&W M76 submachine gun and the AK-47 assault rifle were just cut.
- Early screenshots of the mod also show that you were apparently able to nail headshots, instantly killing an enemy and removing the head in a spray of blood as well. While a more minor form, as typical for shooters, is still in the game - shots to the head do deal slightly better damage, complete with a version of the Faster in Doctor's Story and co-op that wears a metal cage around its head specifically to keep you from shooting it there - this was presumably removed due to not fitting the tone of the game and making combat too easy, with the only enemy whose heads can still be removed by shooting it being the Suiciders (presumably as an unintended side-effect of the programming for them to live up to their name when you get close to them).
- The Watros only encountered in the co-op campaign were apparently meant to be fought as a boss at some point, as players have found unused animations of the things re-submerging themselves and of a full theme song for them that is never used in-game.
