Nightmare Fuel / Splatterhouse
Jennifer has become a mindless beast, and you'd mostly want to too, after seeing these horrors.
The Splatterhouse series is one of the most Body Horror-filled games you will ever find in a video game since it graced the arcades, TurboGrafx-16, and the Sega Genesis. The 2010 remake is no slouch, either.

Splatterhouse (1988)
  • The arcade game employed some trick with its sound to make the effects of the carnage seem to be beamed directly into your inner ear. It cost 25¢ to play, plus $500 in therapy bills.
  • The first level has you lopping the heads off flayed ghouls, while you stride calmly past partially vivisected people in cages and strewn on the floor.
    • The first boss is a room full of shredded human flesh, from which giant leeches leap out and try to attach themselves to you.
  • The boss of Stage 2: the Poltergeist, who would later return as a recurring boss in the other Splatterhouse games. In this game, the angry ghost violently shakes the room around, making stuff fall from the ceiling. It then proceeds to possess a chair, three knives, and a creepy painting of an eyeball. When you beat it, it pulls off a Last Ditch Move, having a chandelier fall from the ceiling (which is an instant kill, whether you're using cheats or not). The music doesn't help, sounding completely deranged, and as the fight progresses, it begins to sound more and more insane.
  • One of the bosses, the Evil Cross, is inside an abandoned church in the original arcade version. Said monster is an upside-down cross with demonic masks firing at you.
  • The Necromancer's demonic chanting is creepy as all get-out.
    • On the flipside, it becomes funny considering that it sounds like he's saying "I'm a-groovin'!". And why wouldn't he, thanks to the music playing in the background?
  • Your girlfriend, Jennifer, who you're supposed to rescue instead mutates into a hideous clawed monstrosity you have to kill, and its evil laugh doesn't make things any better.
  • The fantastically creepy (if not flat-out wrong) Womb Level in the first game where the only enemies are horrid fetuses that first fly off in a sort of bubble, then jump on you and drain your life away. And the boss is a pillar of meat with the bulging heart of the house that sends off millions of these "babies".
    • The heart is actually a uterus. It's more apparent in the arcade version, where its water breaks when it dies (which is also an instant kill, by the way).
  • The final boss, Hell Chaos, is a giant rotting head and hands.
    • Once you realize something about this final boss, though, it somewhat becomes Nightmare Retardant, since the fan-name for Hell Chaos is "Captain Mozzarella" (Its boss theme being the "Requiem/Ballad of Captain Mozzarella") due to to his pizza-like look.

Splatterhouse 2
  • Right before fighting the Warm-Up Boss Bellyache, the enemy that ran away from you witnesses two of its buddies being eaten by the boss. Terrified by this, it tries to flee, but sees you coming in. At the last second, it chooses to be eaten by Bellyache (off-screen, of course) so as to not be slaughtered by Rick. What does that say about the Terror Mask?
  • The bosses of the third level have you fighting off evil hanging fetuses known as Bloodpuppets.
  • The final boss of the second game, known as Ultimate Evil, tops that by being a giant flying mass of red flesh and screaming faces.
    • Oh, and the game pulls a Jump Scare after the credits are over.

Splatterhouse 3
  • The second boss, known as the "Giant Boreworm". His laughter is very haunting.
  • The third game is made all the scarier with pictures of the characters that are low-res, yet photo-realistic. You didn't save Jennifer in time? Then you're immediately treated to that particularly horrifying image of a wrathful, transformed version of Jennifer with four large fangs and two, clearly open eyes, one of which is bulging, as well as facing in a direction for her face to be seen on this page. Good luck sleeping tonight, motherfucker!
    • In fact, there are two images of its kind in-game. The one before it (which you get when the timer reaches 2:00 and you enter a door) has a demonic stare with a bloated head. It's not as scary as the ravage-monster appearance she has in the 0:00 cutscene, but it's THIS image that signifies her death. it can be seen here.
    • The versions of Splatterhouse 3 included in the 2010 remake are either scarier or less scary depending on who you ask.
    • All of the bad endings are scary. Hell, even the good ending qualifies as nightmare fuel!
  • The surprise scare from the teddy bear in the third level. It starts out as a Curb-Stomp Battle at first, and then —WHAM! The teddy bear lets out an unearthly shriek as the ghost possessing the toy rips its way out as a long-armed monster and starts kicking your ass!
    • The preceding two bosses also have fairly gruesome second-phase transformations. The first one's head sloughs off after it's taken enough damage, leaving only its lower jaw and lolling tongue still atop its neck while it keeps attacking (and good news: there's plenty more where this asshole came from, too!), and in Stage 2, the Queen Boreworm's face explodes into a wriggling mass of squirming, maggot-like tendrils.
  • If you decide to not continue after getting a Game Over, Rick's body quickly disintegrates to ashes while his skeleton remains, instead of just laying there intact like in previous games.

Splatterhouse (2010 remake)
  • "The Doll that Bled". As if the title of the level wasn't eerie enough, the titular doll is really going to bother you. First you see a creepy looking doll, which the Mask seems a little cautious about it. It then begins levitating all the furniture around the room, in obvious reference to the second boss in the original game. Then, the doll starts growing tentacles. Lots of tentacles. It then proceeds to grow into a mammoth, vaguely humanoid beast composed entirely of tentacles, wearing the levitated furniture as body armour. From then on, it's okay...until you actually have to rip its jaws off and reach into its bloody mass to reach the Doll.
    • The doll itself is very creepy, falling easily in the Uncanny Valley and says "Mama!" with a chilling, disturbing voice.
  • The Meat Factory. Imagine a factory dedicated entirely to killing. There is no reason for it to be, it is merely an entire complex designed to, well, make "meat". There are even a few walls that are actually composed of mangled human flesh.
  • Ladies and gentlemen... Biggy Man, from the Splatterhouse remake! And yes, you fight him the classic 2D way from original game and the 3D beat-down way. The first time you see him is when the room is pitch dark and sparks suddenly shoot out. Then when you actually get to his fight, he RIPS OFF THE ELEVATOR DOOR to start it.
    • It may double as a funny moment when even the Terror Mask is worried about fighting Biggy Man. Yes, the Terror Mask — of all things — is worried about fighting him, even though Rick is quite plainly pointing a shotgun in his face! In the words upon seeing him in the remake:
    Terror Mask: "Wait, wait, wait — I know this guy! ...yeah, we are screwed."
    • During the fight, HE ESCAPES FROM YOU and then makes you look around an entirely pitch black room with just the revving of his chainsaws dragging across the ground as he rushes toward you at the last second! Have a great, sleepless night.
    • The worst part was the cutscene right after the fight, where Rick repeatedly rams one of Biggy Man's chainsaw hands into him, all the while you can hear him screaming in agony. He's the only monster in the game to actually SCREAM in agony. The screaming... dear God the screaming...
    • Not to mention that he kind of resembles Hell Chaos from the first game (I.E. His skin on his torso).
  • The gigantic Cthulhu-like monster in the tank near the end of Phase 6. Said beastie will growl at you and try to reach Rick by hitting the walls of the tank.
    • What truly makes it creepy is its status as a Big-Lipped Alligator Moment, as there is absolutely zero findable knowledge on what it is and what it is doing down there, and West himself says nothing about it when Rick finds him for the stage's boss fight. One of the scariest things in the entire franchise, indeed.
  • Phase 8 has you enter a house of mirrors. Each room had three, each with the reflection of Jennifer. The first reflection begs you to save her. The second implores you to run and save yourself. The third tells you how pathetic you are. You need to break one of the mirrors to get to the next room. If you choose the wrong one, an evil Jen clone will burst out and try to kill you. And if you run out of time, a small army of Jen clones appear. God help you if you don't have Berserk Mode available. It doesn't help that they're the Demonic Spider variant of Hominis.
  • As if the Womb Level from the original game wasn't enough, Phase 9 is a full-blown Eldritch Location.
  • At the end of Phase 10, a monster version of Jennifer (Or at least, one that resembles, as we later find out) emerges from the wicker man to fight Rick. Although it's a short sequence where she crawls all over Rick's body, it is still incredibly creepy.
  • The ending, the Corrupted got to Jennifer in the end and West finally succeeded.
  • Most of what the Mask says is hilarious. And then there's the rest of its dialogue, reminding you that you are wearing a force of pure evil. For example, when you absorb blood:
    "More... I want more."
    • Or when picking up a pipe:
    "Paint the walls red!"
