History NightmareFuel / ResidentEvil0

* In the kitchen on the back of the train, there is a giant fridge which you can't open. So just walk past it and ignore it. Once you enter the next room and back, a zombie bursts out of the fridge the second you walk past it. A very good (yet likely very predictable if you're familiar with the series) jump scare. Also in the fridge was a bottle of booze, hinting what that person was doing during his last hours hiding from the zombie outbreak.

** Becomes even more unsettling on a second play through when you come to recognize that the old man the leeches took form of is James Marcus.

* ''VideoGame/ResidentEvil0'' doesn't have the [=REmake=]'s Crimson Heads, but it more than makes up for that with an enemy known informally as a Humanoid Leech (often referred to as a "leech zombie", or by its proper name, Mimicry Marcus), [[TheWormThatWalks a swarm of T-Virus leeches that gather together into a human-like form]]. Aside from being full-blown DemonicSpiders, the things just love to hang around in narrow, claustrophobic hallways, move with a disturbing, boneless walk, and have a [[ScareChord really]] disturbing [[https://www.youtube.com/watch?v=F89LW0dfUjc musical theme]]. What's more, humanoid leeches can and will make their way into rooms that were previously ''empty'', meaning that you will reenter a "safe" area, only to find as soon as the screen finishes loading that one of these abominations is ''right in front of you.'' Oh and by the way, you absolutely '''must''' destroy them with either Molotov Cocktails or Flame Rounds from a grenade launcher (or the Handcannon if you have it on another playthrough). Otherwise, you'll render it without a top and then you have all of five seconds to get as far away from it as possible as it [[BodyHorror swells up to a bulbous mass]] and then '''explodes launching leeches all over the place'''. This explosion can kill your characters (especially Rebecca) if they're too close.

** Another potentially frightening part is that sometimes, they're just ''there'', and your first indication is rounding a corner and suddenly there it is, ''[[NothingIsScarier standing there staring at you for a moment while the music starts up]]''. This is best seen on the first floor restroom of the Training Facility. You walk in, pick up bottle, an herb, and gasoline with no issues, but the minute you turn that corner again...

** James Marcus's descent into madness which you can read about slowly through many files littered throughout the game. The man started out as a typical scientist only curious by the virus (in fact, he is annoyed when [[BigBad Oswell]] [[TheUnseen E. Spencer]] constantly approaches him about heading the training facility). He concedes eventually, and of course, with too much power in his hands and his unhealthy obsession with the leeches, he slowly becomes a monster.

Released within the same year as ''VideoGame/ResidentEvilRemake'', the realistic graphics and the detailed enemies of this prequel is just as unsettling.

-->''Rebecca:'' "I never saw him again."

* There are more than a handful of files/documents in the game which Rebecca can collect that reveal Albert Wesker's past with Umbrella. You'd figure she'd probably have something to at least warn Chris Redfield when she meets him or even Enrico when she runs into him again about Wesker's impending betrayal. However, these files conveniently only mention Wesker's name by his first. The player knows which "Albert" the files are talking about, but Rebecca doesn't.

* Marcus going on about how [[LargeHam "the world will burn in an inferno of hate"]] and [[{{Narm}} cringe worthily]] saying "we'll see which one of us is gonna die" is [[NarmCharm hilarious]]. Marcus [[{{Squick}} puking up a storm of slime and leeches mid-sentence and [[BodyHorror transforming into the Queen leech]] is not.

** The worst part? They look like normal people. The first one you find sits there looking like an old man before [[spoiler: his head FALLS ONTO THE FLOOR.]]

** And further dwelling on the scene from above [[spoiler: the old man's body then '''splits into chunks''' as Rebecca screams in horror and then we're treated to the chunks all revealing to be leeches that all begin to huddle together in a grotesque and slimy mass and till they take on the shape of the man again only this time with obviously inhuman skin tone and then as the face reels forward, the camera zooms in as the thing stars at the screen with [[MonochromaticEyes creepy, white, soulless]] eyes.]]
** Becomes even more unsettling on a second play through when you come to recognize that the old man the leeches took form of [[spoiler: is James Marcus]].

* In the Power Plant level, in the same room where [[spoiler: you rescue Billy Coen after he took a tumble into the water]], you find a stack of skeletons all piled on top of one another with grime on them. These were all of Dr. Marcus's victims after he went mad with testing the T-Virus on humans.

* More of an instance of FridgeHorror combined with TearJerker, but Rebecca Chambers' [[spoiler:last meeting with Enrico Marini, her squad captain]] becomes a whole lot chilling considering [[spoiler:he's murdered only the next day by Albert Wesker, his commander and co-patriot whom intentionally sent everybody on this wild goose chase to see how they'd fare against B.O.W.s]] Her words really hammer in the chilling realization:
-->''Rebecca:'' [[spoiler: "I never saw him again."]]
* [[spoiler: Billy, after parting ways with Rebecca, disappears into Raccoon Forest, which is still infested with the zombie dogs. To this day, Capcom hasn't explained what happened to him]].

* The fact that even when [[spoiler: Marcus reveals how Umbrella ultimately backstabbed him and had his two favorite students assassinate him personally]] you simply [[SubvertedTrope cannot]] [[CryForTheDevil feel any]] [[AlasPoorVillain sympathy]] for [[spoiler: him]] after everything you've learned about [[spoiler: him]] throughout the game. Seriously, when you make the likes of [[SmugSnake Albert]] [[AGodAmI Wesker]] and [[MadScientist William]] [[ForScience Birkin]] look like saints in comparison, you really oughta rethink your life. Not to mention Wesker and Birkin [[spoiler: tossing Marcus's corpse into the Sewage Plant]] comes across like [[DramaticIrony poetic justice]] considering [[spoiler: this is exactly what Marcus did to the bodies of everyone he did away with after experimenting on them]].
* [[spoiler: Marcus]] going on about how [[LargeHam "the world will burn in an inferno of hate"]] and [[{{Narm}} cringe worthily]] saying "we'll see which one of us is gonna die" is [[NarmCharm hilarious]]. [[spoiler: Marcus [[{{Squick}} puking up a storm of slime and leeches mid-sentence]] and [[BodyHorror transforming]] into the Queen leech]] is not.
* [[spoiler: Billy's backstory, where his squad [[MoralEventHorizon butchers an innocent village for no real reason and then pins the blame on him when he tries to stop it.]] Making it more horrifying is that ''[[TruthInTelevision this has happened before]]''.]]
** [[spoiler: It goes beyond "no real reason". The soldiers in Billy's unit were in Africa to intervene in a foreign conflict, but instead found themselves getting ambushed and massacred in the jungle. They finally get to their objective, after so many dead comrades and so much hellish fighting, only to find [[ShaggyDogStory the village has no weapons and no rebels.]] It's easy to see how after that, they massacred the villagers because, otherwise, everything they went through would have been AllForNothing, because there ''had'' to be an enemy, otherwise the entire ordeal was meaningless. It gives the soldiers a bit more sympathy, but it does ''not'' excuse what they did. It also makes it especially horrifying, because by the end of it, Billy is the only voice of reason remaining, and is forced to watch his teammates and likely friends go to that dark, horrible place, betraying Billy. And it's Billy alone who we see charged with it and no mention of the other soldiers is made, meaning [[KarmaHoudini the military made him the scapegoat, or his squad simply didn't tell anyone and got away with it.]] ]]
