Resident Evil 5/Nightmare Fuel


 * The fifth game gives us Uroboros. Imagine a writhing mass of worms tearing off someone's skin from the inside out, leaving only the head and limb muscles and bones intact. Now imagine this mass of worms chasing you with the intent of absorbing you, dead or alive, from the outside in....
 * It doesn't help that the second Uroboros is also That One Boss...
 * Fun fact: the name is from the Greek "Ourobouros", which normally refers to the symbol for infinity of a snake swallowing its own tail. It literally means, however..."self-devourer". Yeah. Accurate, huh?
 * The Adjule, Plagas-infected dogs, definitely qualify. Not only do they look like some kind of mutant greyhounds, but then when one takes enough damage their FRIGGIN' HEADS SPLIT APART! Their entire body from the shoulder's up has now become a GAPING MAW, complete with teeth and tentacles coming out!
 * Later in RE5 you get to fight a SWARM of.
 * Chapter 5-1. The entire level has you creepily going around a science facility, and all you ever actually see is 2 initially until the end. You walk around and, horrified, you see the god damn  crawling all over the walls like flies; there's over 2 dozen of them in 2 glass rooms. Any loud noises sets them off, so you quietly head to the next door thinking 'oh god oh god oh god oh god', then you have to break down a door noisily and haul ASS to the elevator. And the elevator takes so long that the first few rows of  will be at the door before it arrives, so you have to shoot them. The 2 glass rooms actually spawn many more  than you can see; namely, there's well over 40, and on the hardest difficulty, they will kill you with 1-2 tongue pulls.
 * Chapter 3-1. Swamp/marshland setting and you have to go to a few islands to grab parts of a key. One of them has crocodiles slowly swimming at you and leaping out to 1 shot you. One has you going along quietly when a swarm of Las Plagas infected locals jump out of the water and kick your ass. Not to forget the chainsaw majini. When they were knocked down once, they permanently are stuck in a swinging state, no more "okay let's time this dodge... haha bastard missed me" to "christ he was only 3m away that time oh god he's coming closer oh god god GODDDDDD". And at one point, you have to fight 2.
 * The Duvalia. Forget doing enough damage and being rewarded with a tentacle in your face - try doing enough damage only for your opponent's whole upper body to be replaced by Audrey II. Complete with biting you in half, the upper of which is probably swallowed, if you get too close. And the actual Venus Flytrap part of it is shelled. The part of it you have to shoot to damage it is the tail hanging off the back. Which is actually the remains of the host's ribcage.
 * Resident Evil 5 also has the Reapers. First response to them is "Oh, a giant insect thing, I can still kill it oh damn it's taking a lot of bullets what's that cloud of smoke it's spraying oh shit it's rearing up run awOHGODWHATTHECHRISTITTOREMYSTOMACHOUTINONEHIT!"
 * When you get hit by them there's
 * The Lost In Nightmares DLC. You go through the first part of the mansion excepting anything to pop out at anytime. And the Blobs that are in the depths of the mansion...and the positively filthy dungeons.
 * On your second playthrough, the Blob CAN sometimes appear in the first part of the Spencer Estate. The good news is, he only pops up on Professional mode. The bad news is he will chase you through the house.
 * What's REALLY terrifying about the Blobs is the kill screen, should you prove an unlucky-enough bastard to become a squelchy sound effect and the horrifying realization that those are Chris' limbs hanging limply from the top of the screen, where the anchor has impaled him through the stomach and he's most likely still (however barely) alive. Go on, try it. Sweet dreams.
 * Simply put, Lost In Nightmares makes copious use of Nothing Is Scarier in its first section, with many bonus scares for those who played the first Resident Evil. The L-shaped hallway is back. When you walk through it the first time, you hear dogs barking outside. When you walk back the other way, . And of course, all the strange stuff that happens, such as hearing footsteps from somewhere in the mansion, or the piano being played. Particularly creepy about the piano part is the fact that when you get to the piano room to check out who's playing it, it is empty - and the only exit is the door you came in through. Once you get into the dungeons, you meet the Guardians of Insanity, complete with short glimpses of them walking past on balconies or through cell doors before you actually do meet them. They have a REALLY creepy theme, and the first one can spawn right around a corner, swinging its hammer down onto you, or on the stairs you just walked down, even when you searched the entire upper floor and absolutely ensured that it was empty.
 * What happened to  She's been captured by her worst enemy, used in experiments, forced to infect people, and forced to fight her old partner and his coworker. And she was completely aware of what she was doing throughout the whole thing.
 * Die in the first level of the game and you are treated to a first person view of the Majini brutally hacking you to bits. Now you know what the victims of Mohammed Farah Aidid went through.
 * The tough Giant Majini you occasionally battle in the Wetlands and Ancient Ruins. The faint ululations you often hear, moments before you catch a glimpse of one in the distance and the battle music starts... Not to mention the gigantic odd-looking masks that mark them out as different, the clubs made out of human skulls they wield, and the fact that they are about 7 feet tall. The fact that they mostly walk calmly towards you and make very few noises when fighting doesn't help either.
 * Dear god, transformation.
 * The sound track that's called "Excecutioner Boss Battle". The theme itself is like something out of a slasher horror film, with one part that sounds like a distorted scream.
