* 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 [[CurbStompBattle has the same result]] [[RealityEnsues in real life]].
* Exploring the ocean can be very unsettling, [[NothingIsScarier 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, 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.
*** NightmareRetardant: there are save files that removes all ocean life and makes the water transparent, for easier navigation.
* [[EmptyRoomPsych The]] [[AbsurdlySpaciousSewer sew]][[NothingIsScarier ers]], accessible by going through the subway, are also creepy because they seem to stretch on forever with no exits. Even though there are almost no people there (save for one engineer towards the entrance), [[ParanoiaFuel you do get the feeling something will come round the corner at any minute.]]
* Trevor Phillips is a really creepy character, especially in his AxCrazy moments, one of which is his opening, [[spoiler: when he stomps the side of Johnny K's face in, leaving a bloody red pulp on the side of the road]].
** There is a strong implication that Trevor moonlights as a serial killer. Even if he isn't a true serial killer, his sick hobby of picking up hitchhikers, driving them up a windy mountain road, and handing them over to a gun-wielding cult is just as creepy.
*** Of course, there are his "friends in the mountains" AKA the Altruist Cult. They are a malevolent group who, according to Ron, take people Trevor brings to them and "just want them for dinner". The fact that '''''[[AxeCrazy Trevor]]''''' is willingly bringing them to the cult like it was a normal day to him is scarier than the cult itself. This is the same man who likely would have killed them in within a moment's notice.
** And after you deliver four people to the cult, [[spoiler: the cult decides to turn on Trevor. [[BullyingADragon 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.]]
* The '''ColdBloodedTorture''' scene is really disturbing, even for the standards of the game.
** Worst part? You can't skip it, 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 [[spoiler: Trevor doesn't kill the guy, but rather drives him to the airport and kindly advises him to get out of Los Santos forever.]]
*** [[spoiler: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.
* In one of the endings [[spoiler: Trevor burns to death]] screaming in agony.
* The scene where [[spoiler: Trevor murders Floyd and his girlfriend]]. The actual murder [[NothingIsScarier isn't]] [[GoryDiscretionShot shown]], but Trevor is covered in blood and the apartment windows are smeared with it. Whatever he did, it was ''messy.''
-->'''Trevor''': You people are not very '''fucking''' nice.
** They have a no holds barred, rather graphic and disturbing torture scene, that you are forced to act out, but THIS is what gets a discretion shot?? [[FridgeHorror What in the world did Trevor do?]]
*** Even worse is his reaction after the act - he's bent over panting, LaughingMad, as if he was [[DissonantSerenity just coming down off a blissful high...]] (shudders).
* Trevor's method of [[spoiler:taking over The Vanilla Unicorn. Leon, the previous manager, literally ends up StuffedIntoTheFridge]]
-->'''Trevor''': (Full-on SlasherSmile) [[KlingonPromotion Prepare to meet your new business partner...]] ([[GoryDiscretionShot Closes the door...]] [[TurnsRed then the screen flashes the same red]] [[OhCrap as his Rampage side activity]])
** Even worse, this is right ''after'' the previously mentioned murder, meaning he's just waltzed into the club [[BloodSplatteredWarrior head-to-toe in blood]], and because [[ApatheticCitizens none of the patrons seemed to care]], [[spoiler: Leon didn't know what was coming until Trevor came through his door...]]
* Remember the [[CatsAreMean cougars]] in ''VideoGame/RedDeadRedemption''? 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.
* 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 [[CouldntFindAPen 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.
* There's the AdultFear of the mission ''Meltdown'', [[spoiler: Michael has to fight off Merryweather, who are threatening to kill his family.]]
* The death of [[spoiler: Molly Schultz. While being chased by Michael at an airport, she runs in front of a jet engine's turbine and is sucked in... [[TurbineBlender and what's left of her could be cleaned up with a mop.]] The fact that one of her hands somehow made it through intact and is just lying in the chunky red goo makes it even worse.]] Even Michael [[MyGodWhatHaveIDone is clearly horrified]] and [[{{Squick}} nauseated]] at what he just saw.
** [[spoiler: 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 [[spoiler:the corpse of Brad.]]
** To go into specifics, it's not [[spoiler: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 [[spoiler: 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]].
* During "Fresh Meat", any time an enemy gets knocked into a meat grinder.
** Or in one case, a [[HollywoodAcid tub of acid]].
* During the family therapy session, [[spoiler: 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.]]
* [[spoiler: The way Peter Dreyfuss tortured, killed and mutilated Lenora Johnson in 1975 was utterly horrifying, [[EvenEvilHasStandards even by GTA standards]]. The only satisfaction is that you will have the option [[PayEvilUntoEvil to track down and kill Dreyfuss]]. ]]
* In TV, there's an ad for a show called "[[ManBitesDog Dude Eat Dog]]". It's... [[{{Squick}} uncomfortable to watch]], [[{{Understatement}} to say the least]], even if played for BlackComedy.
* Some of the missions with the [[ChurchOfHappyology Epsilon Program]], since it involves interacting with members who sound BrainwashedAndCrazy, and have a DarkReprise of the Epsilon Program from their website.
** FridgeHorror comes into play when one of the members is Marnie from ''IV'' whom Niko helped to leave Liberty City in the hopes of kicking her drug habit, only to end up being sucked into a cult.
*** Indeed, Marnie is one of the only sympathetic members of the Epsilon Program - most of them are compromised of {{Jerkass}}es and {{TakeThat}}s to [[NoCelebritiesWereHarmed certain celebrities following a certain Los Angelean faith]], but she's truly a BrokenBird.
** 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 VillainProtagonist hero just faking it, or is he ''really'' becoming brainwashed?
*** [[spoiler: In a bit of NightmareRetardant, [[GetAHoldOfYourselfMan he either snaps out of it at the end]], or reveals he was pulling a BavarianFireDrill the whole time (provided [[ChronicBackstabbingDisorder you kill the Epsilon Security team]], and [[ScrewThisImOuttaHere make off with the car]] [[MoneyDearBoy loaded with cash]])]].
** However, in GTA Online, we get what is quite possibly the most shocking [[TheReveal Reveal]] in GTA history: [[spoiler: if a player dies, they respawn in a FluffyCloudHeaven - and then ''Cris Fromage'' shows up, [[WhosLaughingNow mocking those who considered him a fraud]]. In other words, ''[[TheCloudcuckoolanderWasRight the Epsilon Program was right!]]'' And if that wasn't bad enough, the portrayal of [[DarkMessiah Cris]] as [[GodIsEvil the defacto ruler of GTA's heaven]]... [[ReligionOfEvil doesn't bode too well for those still on Earth...]]]]
* During Predator, [[BigfootSasquatchAndYeti 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.
* Ending B, [[spoiler: where Franklin kills Michael. Michael 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.]]
* [[spoiler: Andreas Sanchez getting [[BoomHeadshot shot in the face]] by Steve Haines, "treating" us to a quick view of the big bloody exit wound in the back of his head]]. It's quick, but ''damn'' [[{{Gorn}} is it messy and detailed!]]
* One of the possible deaths for a Gunman is [[spoiler: getting pinned by a crashing cop car in the Paleto Heist, and suffocating to death in his bomb suit]]. Goes to show how, [[EleventhHourSuperpower even with the best protection money can buy]], AnyoneCanDie... [[CruelAndUnusualDeath and die horribly]].
* If you try to go too far out into the ocean, your vehicle's engine will just stop out of nowhere and it will sink. Now you're stranded in open water, far, far away from land... [[ThreateningShark and a red dot just appeared]] [[OhCrap on your mini-map...]]
** 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 [[ThreateningShark Jaws...]]
* Grove Street. In ''VideoGame/GrandTheftAutoSanAndreas'', 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 GangBangers who are ''not'' NeighborhoodFriendlyGangsters. 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.
* 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! [[YourHeadAsplode His head asplodes]]. [[EvenEvilHasStandards Even Michael thought that Lester went too far]].
