* The premise of the game is a shoutout to the ''Franchise/{{Ghostbusters}}'' franchise.
** As are some of the events. Capturing ghosts. Putting them in a containment vessel. Accidentally releasing the ghosts.
** The howler is reminiscent of Slimer.
** Particularly the 'Soul Whip' weapon is like the Ghostbusters' proton packs.
** In early screenshots Lazarus had a patch on his jacket which resembled the Ghostbusters logo.
** The ghost Librarian in the game references (and expands on) the ghostly librarian in the original ''Film/{{Ghostbusters|1984}}'' movie.
* Film ''Film/Thir13enGhosts'' (2001) - Hunting invisible poltergeist in a junkyard.
* Hawksmoor grabs Anna Steele, Lazarus' partner, in the AbsurdlySpaciousSewer beneath the high school, then pulls her straight up & out of sight. This is like the ambush scene in ''Film/{{Aliens}}'' where a soldier suffers a similar fate.
** Hawksmoor is invisible to Lazarus during this, as the Marines could not see the Aliens in the scene in the movie.
* Movie ''Film/{{Deliverance}}'' - Banjo music and threatening Rednecks.
** And a town flooded by a dam.
* Giant tube worms on an abandoned ship at sea? ''Film/DeepRising''.
* Abandoned/Haunted ship at sea? It's the GhostShip trope, but the ''[[http://www.imdb.com/title/tt0288477/ Ghost Ship]]'' movie.
* Movie ''Film/{{Poltergeist}}'' - poltergeists
* ''Film/{{Psycho}}'' - [[spoiler: Lady [=DeMontford=] was dead all along. Her corpse can be seen rocking in a rocking chair in the basement of the Evil [=DeMontford=] Mansion.]]
* The cyborg form that Digital Richmond becomes following [[spoiler: Lazarus' death]] is a clear homage to the ''Franchise/RoboCop'' films - his chaingun and rocket-launcher are both based on ''Film/RoboCop2'''s weaponry and the mechanical noises of his legs and arms are all sampled from the films.
* During the prison level, Lazarus Jones makes his way through an underground maze featuring steam-pipes that fire hot steam jets and giant spinning cogs. After completing the maze he emerges in a shower-room surrounded from above by gun-wielding ghost guards. This is very similar to the underwater Navy SEAL incursion sequence from the 1996 action film ''Film/TheRock''.
* Movie ''Franchise/TheTexasChainsawMassacre'': Chainsaw wielding redneck wearing a crocodile head and a bloody butcher's apron.
* {{Transformers}} (junked) vehicles assemble into a giant robot.
* Movie ''Wes Craven's Film/{{Shocker}}'' - Agglin electrified prisoner.
* A giant alligator in a swamp. A reference to too many movies to list. Just check the Internet Movie database for movies with 'alligator' or 'crocodile' in the name. Since it ends up being wrestled with, there's a vague allusion to the ''Film/CrocodileDundee'' movies.


* Jerry Reed's ''Amos Moses''. The one-armed swamp monster. "He could trap the biggest, meanest alligator, and only use one arm. Only got one cause the alligator bit it."

* The ship's captain [[MeaningfulName Kraken]] is turned into a giant multi-tentacled monstrosity that eats human souls. [[Franchise/CthulhuMythos Cthulhu]] anyone?

[[folder:Real Life]]
* There's a bell with a crack like the Liberty Bell: [[spoiler: Lazarus rings it to free ghosts of townspeople]].
* Agglin, and the Warden's rant about no one escaping, are obvious references to the three RealLife prisoners who escaped Alcatraz Prison, Frank Morris, John Anglin and Clarence Anglin
* The Pulse gun that Lazarus uses throughout the game strongly resembles the Calico [=M960A=] rifle, complete with a helical magazine design.
* Colonel Fortesque's head plays the RealLife game Hot/Cold with his headless body.

[[folder: Video Games]]
* The Cemetary area architecture, lighting and music are reminiscent of ''VideoGame/{{Ico}}''.
** Hawksmoor's castle has structure and color like the Queen's castle in ''VideoGame/{{Ico}}''.
* Tree roots growing through the [=DeMontford=] Mansion, like the tree under Decerto in the original ''Videogame/AloneInTheDark1992''. [[spoiler: The tree was the source of the mansion's evil.]]
** The [=DeMontford=] Mansion levels is one big shout-out to the original ''Videogame/AloneInTheDark1992''.
* shout-out to SCEE Cambridge's all-time best work, too! Surely Colonel Fortesque is a reference to - or, in fact, a descendant of - ''VideoGame/MediEvil'''s Sir Daniel Fortesque?
** Sergeant (Sir Daniel) Fortesque's a sergeant InNameOnly, similarly to how Colonel Fortesque's heroic exploits are really just historical embellishment.
** Plus, when you defeat Captain Kraken, Colonel Fortesque admits that this is his first victory - Captain Fortesque never killed his opponent in ''[=MediEvil=]'', instead falling during the first volley of arrows.
** "''The Fortesque family have been fighting man and boy for Old Blighty for over a thousand years. We've never let a little thing like ''death'' get in the way. Why, there's a Fortesque on every battlefield in the civilized world. Agincourt, dead. Waterloo, dead. Dunkirk, dead.''" - Colonel Fortesque, embellishing historically.
** And they're both silly.
* In the New School Theatre the poltergeists telekinetically raise chairs into the air and move them in geometric patterns. Psycho Mantis does the same thing in ''VideoGame/MetalGearSolid.'' [[http://www.youtube.com/watch?v=GMRD4YpDzTM&feature=related Here]] starting at 2:50.
* There's a low-res poster of a bikini-model in the Janitor's office of the old highschool, much like the low-res "EXCITE! 1998" bikini model poster in the final level of the original ''VideoGame/ResidentEvil.''
* When Digital Richmond's robot form unexpectedly falls through the floor, this is a ShoutOut to various other SurvivalHorror games that use this mechanic to advance the plot.
** ''VideoGame/SilentHill1'' - in the mall.
** ''VideoGame/ResidentEvil2'' - balcony in the library.
** ''VideoGame/ResidentEvilCodeVeronica'' - Walkway above the jeep area.
* The little Redneck girl Lazarus has to escort out of the swamp bears more than a passing resemblance to Sherry, the little girl Claire has to escort in ''VideoGame/ResidentEvil2''. The blonde hair particularly.
** Sherry herself is a shoutout to the kidnapped little girl Grace Saunders in ''VideoGame/AloneInTheDark2''.
* Some ghosts make a staticky background noise like the monster-detecting radio in the ''Franchise/SilentHill'' series. Great for knowing they're around and how close they are.
* ''VideoGame/SilentHill2'' - The transporting doors in the [=DeMontford=] Mansion are the same as the transporting doors in the decrepit Lake View Hotel in ''VideoGame/SilentHill2''.
* The Swamp Phantom, a giant naked, extremely well-muscled man, is a dead ringer for the Tyrant monsters in ''VideoGame/ResidentEvil'' and ''VideoGame/ResidentEvilCodeVeronica'', right down to the misshapen right hand.
** To be clear, in the ''Franchise/ResidentEvil'' games the Tyrants have claw/clubs for a right hand. The Swamp Phantom is completely missing his right forearm and hand.
* Giant crocodile in the swamp could be a Shout Out to the giant crocodile in ''VideoGame/ResidentEvil2''.
* Lazarus has to shoot a bell to advance at one point. Lara Croft had to do the same thing in ''Franchise/TombRaider 2''.
* The [[http://images9.gry-online.pl/galeria/galeria_duze3/67805109.jpg ghost enemies' design]] is based off [[http://vignette2.wikia.nocookie.net/soulcalibur/images/f/f5/C_voldo_3p.jpg/revision/latest?cb=20111113230212 Voldo's third costume]] from ''[[VideoGame/SoulSeries Soul Calibusr II.]]''
