* TheDanza: Heather is named after the actress who voiced her. Her last name is not given in the credits, giving an impression of the [[CharacterAsHimself character as herself]], to the point that early promotional materials had her character name listed using the actress' full one -- Heather Morris. Justified in that listing Heather's ''real'' last name [[spoiler:-- Mason (as in, [[SilentHill1 Harry]]'s daughter) --]] would have [[InterfaceSpoiler spoiled a fairly significant plot point]] that comes about halfway through the game.
* HeyItsThatVoice: The HD Collection.
** Heather is [[BlueSeed Momiji]] and [[Anime/NeonGenesisEvangelion Rei]].
** Vincent is [[Manga/{{Naruto}} Sasuke]], [[Anime/CodeGeass Suzaku]], and [[WesternAnimation/Ben10AlienForce Ben]].
** Claudia is [[VideoGame/{{Catherine}} Catherine]], [[Manga/FullmetalAlchemist Lust]], [[Manga/{{Bleach}} Halibel]], and [[VampireKnight Maria]].
* KonamiCode: Used to turn Douglas from a hard-boiled detective into an utterly creepy (almost) nude flasher.
