Nightmare Fuel: Batman: Arkham Origins
Batman: Arkham Origins might not have the long term scare factor of City, but it compensates for this with an upfront maniacally scary story.
Batman performs a High-Altitude Interrogation on one of Penguin's thugs, with the guy in question previously being unconscious beforehand. As he wakes up, we see things from his Point of View, showing exactly just how frightening it would be to actually be caught by Batman. Imagine waking up dozens, if not hundreds, of feet above the ground, upside down, with no idea how you got there, only to look up and see this shadowy black figure that everyone else you know is terrified of holding onto you?
Not only that, but despite being able to see how high up he was, the thug didn't start freaking out until he noticed Batman! Clearly, his reputation precedes him.
As Batman carefully makes his way up to the very top of the Royal Hotel, Bane ambushes him and delivers him at the feet of a much more spry and overenthusiastically insane Joker, who's revealed to have a table covered with detonators for bombs in hidden locations all across the city. Not only does he threaten to activate the explosives within the Hotel itself, sufficiently convincing Bane to give them some privacy, he even triggers one wired to a location right outside the window, destroying the building completely. It was an empty construction site, but even so…
From the perspective of the Blackgate Prison staff, having not only a prison break assisted by Killer Croc, but the execution of the police commissioner within their own halls while being powerless to do anything about it.
An example that's only terrifying if you've played Arkham City: Calendar Man's cell at Blackgate. Scribbled on the wall is a 'to-do list', which name drops several of the horrific murders you hear about in City. The worst part? Even though he sees the list, Batman can do nothing to save those people.
While fighting on the roof, Batman is thrown into a sudden quick-time event where Croc holds him down and attempts to bite off his face, getting progressively closer with each snap of his jaws.
When Black Mask is ungagged and begins to threaten the Joker's life for usurping him as gang leader, Joker flies into a rage and viciously beats him, screaming at him for not "playing along" in his real voice.
Look into the side rooms en route to Black Mask's hidden drug manufacturing plant. One is filled with formaldehyde-filled mason jars which are themselves filled with dismembered body parts: hands, feet and more than a few heads.
It doesn't help that in the forefront of all those jars is one of the victims that is placed in an "experimental" branded barrel of formaldehyde staring back at you with that one eye.
His office in the drug lab has not only multiple skulls labelled in a glass case, but a fully-stocked torture facility complete with a plush armchair and a tripod camera.
Also worth mentioning, Located at the same location of where the aforementioned jars are kept. If you look down at the lower right corner of the shelves you'll find a bunch of collection of suspicious looking items. A mop, bucket, a pair of gloves and a canister of solution that is obviously bleach. ... Apparently, Black Mask's goons obviously do "clean-up" jobs after rubbing out those that were a threat to Roman Sionis and his gang. Kind of makes you wonder of what they do before or during the events of Origins. There's also a bit of those same items in Sionis's Office where he does his favorite "hobbies".
The whole corruption of the G.C.P.D most particularly the head of its S.W.A.T teams Branden. But corruption aside, the moment that is well captured is when Gordon corners Batman with Branden behind him ready to open fire on both Batman and Gordon. If Batman hadn't thrown that smoke bomb...
Here's one that shows how truly corrupt most of the Gotham police force is. Throughout the station, especially noticeable in certain of the interrogation rooms, some of the floors are stained with dried blood.
One of the police officers hanging around Enigma's hideout tells a sickening anecdote of how he mistreated a female civilian without any just cause. She apparently came back to file a complaint against the department... only to find the officer himself sitting at the desk, grinning his head off and asking how he might be of assistance. As she started to scream about what a disgrace he was, he had her booked on drunk and disorderly conduct, and tossed her in a holding cell. (He apparently "visited" her as well during her time there, to "teach her not to make a scene next time".) She left the GCPD a broken woman - even apologizing to the officer on her way out, something he particularly enjoyed. Fortunately, you have the option of breaking the officer as well.
You come across SWAT officers beating down homeless people in the station, with their colleagues cheering them on. After putting a stop to this, when Batman suggests they get themselves to a homeless shelter, the man he's speaking to tells him that's where the cops round them up. Implying that the cops have not only been doing this for a long time, certainly far longer than Anarky has been around, thus eliminating the possibility of simply using brutal interrogation methods to gain information on their "boss", but that they do it for entertainment.
Joker throwing the Electrocutioner out of the penthouse window. Just the fact that he falls such a long way so fast, and you can hear him screaming.
What tops this Nightmare Fuel page would have to be the final confrontation against Bane. During a long grueling grudge match against Bane and the eventual apprehending of the Joker. Joker hooks Bane up to a heart monitor that links it to the electric chair to kill Joker. Gordon and the head warden of Blackgate then storm in to unstrap the wily Joker only then to have Gordon being countered and pulled in and held at gunpoint. Joker knew that in order to stop it from being activated Batman would have to have killed Bane in order to prevent the electric chair from killing both himself and Cpt. James Gordon. The fight is fierce, physical and utterly brutal. Do things get better afterwards? No. It doesn't. It starts after, when Bane gets resuscitated back to life, he goes all out. He injects himself with a new strand of experimental form of Venom... turning him into a literal hulking abomination. You're given 10 minutes of taking down this unGodly sight of a man. What makes this fight worse and hectic? He adapts on whatever you throwathim! ...The fight is the stuff of true nightmares.
What makes Bane even more terrifying is that in previous entries, Bane was never that fast. In Origins, he is terrifyingly faster and can outright obliterate you if you're not quick enough.
The trip up to meet the Joker in the hotel. The man converted a penthouse into an Amusement Park of Doom which you have to make your way through. Along the way are bodies with TV or Christmas ornaments stuck on their heads as well as a few thugs stuck in Death Traps. There are dead bodies everywhere. Some are his own men, it truly hammers home how monstrous the Joker is.
The Joker himself, this is because he's just in it for himself this time and just sees Batman as a distraction. As such, he's particularly much more brutal in his methods and he just does not care at all if he lives or dies. He even gives Batman a "What the Hell, Hero?" after he saves him from getting blown off the hotel. Stating he deserves to die. But after Batman saves him again, this just start off his fascination with him, like he's now found a purpose to live.
The Joker's always been crazy, but it's much more obvious here. He's completely Ax-Crazy. This game makes it clear more than any other how deeply psychotic he is, and it's terrifying just how easy it is to send him from Faux Affably Evil to homicidal rage, since there's no way of knowing what's going to do it.
An extremely flexible woman contorting around Batman in skimpy clothing might sound sexy in theory, but Copperhead's movements are reminiscent of basically every creature that could crawl on your body and fill you with venom while you're helpless with fear, from the obvious copperhead snake to a large poisonous spider. Her bio even states that she crushes some of her victims this way. And this is in addition to the hallucination sequence, with Copperhead lunging and taunting Batman about his impending death while previous failures jeer about his incompetence.
The fanservice is further ruined when she hisses and unveils her tongue. Compared to the rest of her human body (save her glowing eyes), that reptilian tongue is jarringly different and all kinds of wrong.
When you rescue the Mad Hatter's most recent 'Alice,' she just breaks down weeping. Batman tries to tell her that it's going to be okay...
'Alice': No...it's not.
Batman's battle with Firefly on the bridge. A cacophony of explosions, flaming cars and falling rubble. And it gets more and more hellish as it progresses.
At the end, Batman punches his visor so hard it cracks enough to see his face. We don't see all of it, but what we do see...
Just like in Arkham City, Penguin keeps lots of glass cases on his ship... cases containing the corpses of men who failed or betrayed him. The worst one is pinned to the wall by knives.
Batman's interrogations and behaviour in cutscenes are generally much more frightening in this game, because both his reputation and self-control are at a much lower level than in the other games. In City Batman could get thugs to talk with only a few quiet words, often with the threat more implied than explicit because he was so much The Dreaded that he didn't need to do more, but here he looks like he might lose his temper at any moment and slaughter the thug he's interrogating, and his cutscene No Holds Barred Beatdowns of the already helpless Penguin, Black Mask and Joker aren't something you'd expect from the more mature Batman to which we've become accustomed. Seeing the fledgling Batman so barely containing his inner darkness makes it quite clear how dangerous he could be if he slipped up, and seeing the customary Tranquil Fury replaced with something closer to The Berserker can be quite shocking.
The "Cold, Cold Heart" DLC explains how Victor realized he would die if he went in above zero temperatures after the accident. There was a security guard who was also affected by the cryo-blast. Not sure what was going on, he stumbled desperately out of the frozen lab and into the entrance area...where he promptly died of heat stroke as a result of Ferris Boyle turning on the quarantine features of the lab.
Speaking of Boyle: The original Boyle from Batman: The Animated Series was an opportunistic scumbag for sure, but he was was correct that Victor's work wasn't authorized and things didn't get out of hand until Victor pulled a gun on him. The Boyle here, in his version of the accident takes Nora away, against his agreement, for the express purpose of experimenting on her and the process Victor used. He has his guards hold Victor back and pistol whips him before kicking him into his equipment, and when that sets off the chain of events that causes Victor to become Mister Freeze? He just stands and watches for a moment, not trying to get help or intervene, before running off. When Batman finally rescues him, he freezes Batman with a broken cooling pipe and taunts a helpless Victor that he'll kill Nora before he kills him, just so he can see her slip away, all the while bashing him over the head with a piece of Victor's suit repeatedly. What's worse is that all of this, his vile personality, is wrapped up in a demeanor so kind and innocent that he had the World's Greatest Detective fooled. There's Adaptational Villainy, and then there's this.
