* AuthorExistenceFailure: A remake to this and ''VideoGame/BlueStinger'' were both planned, along with XBox sequels, but never came to fruition due to the untimely death of Climax Graphics' president, also the mastermind behind the games.
* {{Blooper}}: In "Killer Department Store", the narrator screws up one of his lines.
-->Narrator: In his warped mi- ...In his warped mind...
* TheDanza: Jorg was voiced by Jorg Tittel.
* DoingItForTheArt: Yes, really. Creator Shinya Nishigaki had once remarked that he honestly didn't care if ''Illbleed'' wasn't a blockbuster title, and that so long as even one person enjoyed playing it, then he considered the game a success.
* HeyItsThatVoice: Sonic fans will probably recognize Eriko and Kevin's voices... They're voiced by Lani Minella and Ryan Drummond, Rouge and Sonic's voice actors pre-4Kids.
** The original trailer for the game is narrated by Jon St. John, in full DukeNukem mode.
* LetsPlay: One by LetsPlay/{{Supergreatfriend}}, where he shows the various characters and scares in the game whilst questioning the game's internal logic.
* NamesTheSame: "The Revenge of Queen Worm" takes place in "Camp David", but it's not the country retreat of the President of the United States (despite a line in the opening narration implying that it is).
* WhatCouldHaveBeen: The Remake and Xbox Sequel.
** If one looks at screenshots on IGN ([[http://media.dreamcast.ign.com/media/014/014418/imgs_1.html here]]), the pulse meter had a different layout, there are a few traps and areas that don't appear to have been in the game, Cork having a much more [[WesternAnimation/ToyStory Woody]]-like face, and a concept map of the park that looks vastly different from what's in the final game.
** Trailers show that enemies also appeared to be in the park itself, and "OHNOMAN" seemed to be a normal enemy, along with layouts and other things that, again, don't appear in the game proper.
