Trevor during his Ax-Crazy moments in particular is a horrifying sight to behold both from the player's perspective as well as the perspective of his victims. His first mission "Mr. Philips", has him stomp the side of Johnny K's face in during an argument, leaving a bloody red pulp on the side of the road. After that, Trevor proceeds to mow down the rest of Klebitz's faction of the Lost MC with little to no resistance! Imagine you are one of the Lost and you just got word Johnny K along with Terry and Clay are dead thanks to that local eccentric meth dealer who's been known to throw temper tantrums out of the blue. As you prepare yourself for combat, you see said dealer whip out a shotgun and lay waste to your entire gang almost as if he's supernatural!.
"WHO THE FUCK ARE YOU SPEAKING TO?! WHO?! WHO?! I'M TALKIN' TO YOU, HUH?! YOU FUCK! NEXT TIME, DON'T GET IN MY FUCKIN' FACE! I JUST SAW A FUCKIN' GHOST AND I GOTTA HEAR YOUR CRAP?! GET UP! GET UP!! FUCK YOU, THEN!"
One of the Gold Medal requirements for this mission is to kill every last one of them. Just imagine this again from their viewpoint: you are running away from the lunatic who, not more than a few minutes ago, just wiped out your faction, but he hasn't had his fill yet, so the guy goes after your friends, blows their heads off, and then finally goes after you.
When that opening cutscene is over, before getting into the truck, turn around and take a close look at Johnny's corpse with your phone camera or in first-person view. The really graphic bits of Trevor's attack were left mostly offscreen, but a close look at the corpse reveals that Trevor literally stomped Johnny's head in until his brains were showing. This also means that when Trevor taunts Terry and Clay later by speaking to a piece of Johnny's brain on his boot, that's not just a piece of gore, that really is part of his brain!
The Altruist Cult. They are a malevolent group who, according to Ron, take people Trevor brings to them and "just want them for dinner".
And after you deliver four people to the cult, the cult decides to turn on Trevor. Big mistake for the cultists, but it's still pretty chilling to see their ritual, which was undoubtedly one of the last things all those victims you delivered saw.
One of the random encounters is about his members trying to kidnap a young lady.
Ending B. It is probably one of the darkest moments in the entire GTA series.
The fact that most of the story revolves around Michael and later ends up dead is quite jarring.
Franklin himself during the plot of the mission. He seems so ruthless and unsympathetic, probably bordering on Out-of-Character Moment.
Michael's persective. He leaves no stone unturned in making you feel guilty as shit for double-crossing him after he just salvaged his family life and looked out for Franklin as if he was family, too; even if you change your mind and try to save him, he lets himself drop to his death.
The image of Michael a bloody, dead mess on the pavement is a pretty horrific way to end the story.
Ending A is no better: at one point, Trevor burns to death screaming in agony.
Trevor: MICHAEL!! AH, FUCK! I THOUGHT I WAS WITH ONE JUDAS!! I'M SURROUNDED BY THEM!!! YOU...FAKE...MOTHER...FUCKERS!! YOU WANT A PIECE OF ME?! FUCKIN' COME GET ME!! YOU WANNA KILL ME?! TAKE A FUCKING SHOT!!
How the whole Kill Trevor ending turns out is pretty unnerving, especially the fact that after Franklin or Michael kills Trevor, Michael goes on a rant in which he aggressively tries to justify what they did. It's been noted that his behavior and mannerisms in this instance are very similar, if not identical, to the way Trevor actedthroughout the entire game.
Worst part? You can't skip it* Unless you know who the target is already and shoot him early, but even then you still have to go through two of the four torture segments first before you get the option, so if you're queasy and uncomfortable with torture scenes, much less interactive torture scenes, you are shit out of luck if you want to beat this game. The only consolation is that Trevor doesn't kill the guy, but rather drives him to the airport and kindly advises him to get out of Los Santos forever.
Even this moment is horrifying, if only for the revelation that although Trevor enthusiastically participated in the brutality, he knew from the start the guy would tell them everything, and it was all totally pointless.
To put in light just how horrifying this part of the game is: some GTA fans, who are known to be completely unflinching towards the worst blood and gore that the series has had to offer, CRINGE at this scene. Most of it has to do with the fact that the horror of the violence is completely played straight. No form of glorification in the slightest.
The worst part is that the victim seems to be an innocent man, and after the mission is done, it doesn't seem like he'll see his family again. And before the poor guy was tortured by the FIB, he was being tortured by the IAA.
With the sharks in the game, they often don't immediately attack you. Instead, they tend to stalk and circle around you before going in for the insta kill.
At which point, your character is violently shaken in the jaws of the shark, letting out a gurgling scream. As the "WASTED" screen pops up, your character remains frozen in an expression of terror, sinking into the depths in a cloud of blood.
What's worse is that unlike cougars which you can easily fend of with your overpowered minigun or auto shotgun the only thing you have underwater as a weapon is the knife and fighting a shark with a knife more often than not has the same resultas in real life.
Exploring the ocean can be very unsettling, even without the constant threat of sharks. The deeper you go, the less light there is, and massive underwater cliffs and spires appear practically out of nowhere constantly. The submarine has no radio (unless you're playing the Xbox One, Playstation 4 or PC versions), so you're stuck listening to either the eerie ambient music, the droning of the submersible's engines, or various strange undersea noises.
Then there's 'crush depth.' diving too deep with the submersible will cause it to visibly compact under the water pressure. What's worse is some of the nuclear waste pickups require you to dive dangerously close, or into that depth.
For added horror, try crashing a plane in the ocean with the invincibility cheat turned on. But if you get down deep enough (as in, at the point where your boat or plane stalls and sinks into the ocean), not even invincibility will save you - you will die. While it's most likely due to technical limitations, it really sells just how terrifyingly deepthe ocean really is. The guy who crashed the plane with invincibility on just above? It got so dark and deep he was legitimately terrified and bailed from the plane to get back to shore.
On a related note... Diving deep in the dark ocean is scary enough. Diving around looking for nuclear waste and stumbling on a dead body lying on the ocean floor? Ten times worse! And then, if you research enough, you learn that there are EIGHT dead bodies lying on the ocean floor, the work of the now-deceased Infinity Killer who hid the bodies in a secret place... and YOU just stumbled on that place! Nuclear waste or not, you will never want to explore the GTA ocean ever again!
Remember the cougars in Red Dead Redemption? They're back, waiting for you should you choose to head into the countryside. They're not as tough to kill as the ones in Red Dead, and they'll run away from you if you're in a vehicle, but the sound of their yowling is still enough to send a chill down your spine. Oh, and while the Red Dead cougars would usually take two hits to kill you at full health, these cougars can do it in just one.
Their killing animation has also changed from a comically unrealistic looking scratch to a much more realistic pounce then bite into your torso/neck.
Worse is - you are virtually guaranteed to find them when playing the hunting minigame, and you can't use invincibility in missions, so if you can't run away fast enough (or climb on top of something) you will get killed. It's the inevitability of them spotting you and chasing you faster than you can run away that is particularly scary.
If you've taken a taxi to the hunting area, sometimes your taxi driver can be attacked by a cougar.
To a lesser extent, you can also get attacked by dogs. It usually happens if you attack their owner, but sometimes it's just triggered by going too close. There are sometimes police dogs too.
Elk can occasionally run in front of cars, which is quite a surprise if you see it happening well away from the hunting area where you'd normally find them.
Go to Mount Gordo between 23:00 and 00:00 and you'll see Jolene Cranley-Evans. The catch? She's been dead since 1978.
It gets worse. When you approach her, she disappears and leaves a message in blood. The message? Jock. As in Jock Cranley. You know, one of the candidates in the campaign for governor? One of the websites in the game implies that Jock murdered his wife.
You can go to a little site down Mount Gordo with a few camping tents and possibly a van. Now, look up Mount Gordo and you can spot the ghost floating up there at the mountain, staring at you, which is eery itself. Now turn up your volume and soon enough, you'll hear a blood curling scream coming from up the mountain...and if you're wearing headsets, you'll hear whispers right next to you.
There's the Adult Fear of the mission Meltdown, Michael has to fight off Merryweather, who are threatening to kill his family.
The worst part may be that one of the Merryweather mercenaries gets to Tracy's room and holds her at gunpoint while using her as a Human Shield, if you take too long lining up the shot the merc executes her in front of her parents, and due to her struggling to get free another possible outcome is for Michael to accidentally kill his own daughter instead.
Did we mention it was completely unnecessary? The reason Michael was chasing Molly, was because she had stolen the only hard copy of the movie Michael had produced so it wouldn't be put out. Of course, being 2013, there's plenty of digital copies, but the director, the only one who knew of them at the time, didn't see fit to remind anyone.
Trevor discovering the corpse of Brad.
To go into specifics, it's not the corpse of Brad itself that is the terrifying part of this scene, it's the fact that Trevor, already unhinged at this point just discovered that Michael, one of his best friends, was responsible for the death of his other best friend, and now because of discovering this, any semblance of a deep friendship between them is destroyed.
Brad's corpse is pretty frightening, though. Nine years of decomposition will result in quite the Nightmare Face.
During "Fresh Meat", any time an enemy gets knocked into a meat grinder.
If the player doesn't save Michael in time or they're just a sadist, and they're switched to him, they'll be "treated," to a scene of Michael actually begging for the Triads to turn off the meat grinder about 5 seconds before being slowly ripped apart, audible screams and all. You can even hear him scream over the muted Game Over screen.
During the family therapy session, Michael tells Amanda, right in front of their children and in no uncertain terms, that if she were to report him to the police, he would kill her. The look on his face and tone of his voice are as terrifying as anything Trevor's ever done.
While Michael may have just been playing along, the fact that his dialogue pretty much dissolves into their catchphrase during their quests can be quite unnerving. Is our Villain Protagonist hero just faking it, or is he really becoming brainwashed?
During Predator, bigfoot shows up as you're using thermal scopes to snipe. When you focus on him, he disappears. However, if you're not familiar with GA mythology, it just looks like a person was standing there until you looked at him, and then he disappeared when you began watching him.
Same if you're in an airplane and fly too far out into the ocean. You can either (a) slowly fall into the ocean in the cockpit of a plane with dead engines, or (b) jump out and free-fall into the ocean. Either way, you'll be stranded in open waters, miles from land and have to fear Jaws...
Grove Street. In Grand Theft Auto: San Andreas, it was the safest place for the player in Los Santos, being the site of your first hideout and completely free of Ballas control. In this game, it's the complete opposite. It's a dismal and grungy ghetto crawling with Gang Bangers who are notNeighborhood Friendly Gangsters. Every single one of them is armed and liable to open fire at the slightest provocation (up to and including the crime of simply not being one of them). Just like a real life ghetto, this is not a place you want to go to alone, if at all.
Heck anytime you have to fight the Ballas in missions is heart pounding. The two missions "The Long Stretch" and "Hood Safari" are basically escape or die missions.
Even FIGHTING with the Ballas (or any gang in general) can be quite terrifying. What could be just a simple fistfight with some Gang Bangers could turn into a shootout. Bonus points if you don't even have a weapon yet and all you can really do is get the hell out of there. Just goes to show how dangerous it is to go around looking for trouble in places like these.
In Friend Request, Michael, at the behest of Lester, plants a device into a prototype LifeInvader phone and is told to call it when the founder, Jay Norris, demonstrates it. The kicker? The device was an explosive. He's right out in front of the public, he holds the ringing phone up to his ear, then BOOM! His head asplodes. Even Michael thought that Lester went too far.
Really, the idea of Lester getting mad at someone at all. While the people he targets in Assassination missions are far from undeserving, they had no idea that they had attracted the ire of a dumpy little man who is suddenly sending assassins after them. He's like if Anonymous had access to a crew of hardcore criminals to kill anyone that displeased them. This is further compounded in the multiplayer; you can call Lester in at any time to put a bounty on other players, for anyreason at all at any time.
The mission "Dead Man Walking". Aside from waking up in a morgue with corpses, whilst you'll probably never know of its existence unless you let it happen out of curiosity or find it on YouTube, but if you let the morgue doctors who somehow can't tell that you are not dead be long enough without waking up, they will actually start an AUTOPSY on you whilst YOU ARE STILL ALIVE. It's not just any autopsy either; they CUT YOUR RIBCAGE OPEN WITH A HACKSAW whilst you see your blood squirting out and hear the bones being cut out just as it fades to the mission failed screen.
While the peyote sessions are funny for the most part, some of them can take on a more sinister edge from the interior monologue. Of note is when Trevor becomes a tiger shark, going from his usual persona to darkly serene and sinister.
The new Slasher game mode for GTA Online. You have only a flashlight, the whole place is dark and someone is out there, hunting you with a shotgun. You better hide alright.
Not only that, but it brings a new ambient score to the game that sounds like something straight out of Manhunt.
Slasher IV is the worst. You can't see anything and you're totally reliant on your flashlight only. See that light coming down the tunnel? Is it coming from a partner...or the slasher?
Pretty much the entirety of this video that shows Trevor's mind finally decaying to the point of no control. If you have a fear of clowns, please do not watch this video.
Trevor's is especially terrifying when you remember it's heavily implied he was molested by a clown.
GTA Online itself can be this on Free Mode. There is no one to trust and most players just shoot on sight once they see you, out of protection or pure entertainment, and they may spend hours of their time killing you and over until you run away or quit. Just imagine if there were 30 clones of Trevor scattered around San Andreas doing God-knows-what. That's exactly how scary it is.
Seeing a red blip on the map coming towards you at high speed can be this. Extra points if they suddenly vanish from the map because they used Lester's hide blip ability and even more extra points if the blip has the shape of a tank or a jet.
Every once or so often, you'll see a police cruiser chasing a car with 2-4 criminals in it. Usually, they'll drive away and be gone for good, but there are also times where both sides exit their vehicles and shoot at each other. While it may be a little annoying at times, it's also quite disturbing to see just how chaotic the streets of Los Santos are.
The show Kung Fu Rainbow Lazer Force, an evangelical Christian parody of Power Rangers has a scene where the team encounters a teenage couple who they claim have "unnatural desires". When the team proceeds to mock the asthmatic boyfriend in the relationship, they discover the boy has pictures of Renaissance human sculptures, which the team counts as "amateur pornography", and end up killing him (with a heavy amount of Gorn too to save the girlfriend. It doesn't stop the girlfriend from having a mental breakdown and end up meeting the exact same fate as her lover. To think of it, it crosses the border of Squick and can come off as unsettling, even for the fact that the show is a parody of extreme conservative values
Later in the show, Louisa, Sebastian Kayden's Mexican house maid, ends up getting killed the exact same way, although this time, it is accidentally done in a fit of rage from Sebastian seeing barely-clad cheerleaders. It still can't be excused from being utterly disgusting, however.
The Oop North characters of Nigel and Mrs. Thornhill in the "Vinewood Souvenirs" strand of missions (done by Trevor, to make matters worse), spend their tourism of Los Santos by stalking celebrities, including stealing several "memorabilia" from them (including Kerry Mc Intosh's dog collar, Tyler Dixon's swimming shorts, Willy of Love Fist's golden tooth and Mark Fostenburg's golf clubs). With the exception of Kerry Mc Intosh, you are also given the option to kill the celebrities, to make it worse.
And then there's the kidnapping of Al Di Napoli, where the British friends leave Trevor to deal with the celebrity. One possible outcome (including the one needed for the golden achievement) is by leaving the rental car (complete with Di Napoli in the trunk) left on a train track while a freight train is coming at a high speed. Even though it's optional, it's still frightening to think of, especially when the closer you get to the train tracks, Di Napoli begs you to pull over in exchange for a large sum of three thousand (or, thirty thousand) dollars.
Regardless of which you choose, it's still implied that Nigel and Thornhill are still in Los Santos after they cut ties with Trevor, continuing to stalk celebrities... unsettling indeed.
