History NightmareFuel / MassEffect2

** Difficult-to-get [[http://youtu.be/CqtAHNQT3-w content]], lines from Legion who remembers when the geth touched Sovereign's minds, strongly suggests that the melted-down humans aren't just killed and turned into raw materials, but ''[[AndIMustScream still aware]]'', or at least existent.

** The point above is actually not entirely correct. The Viper Nebula only has one inhabited system with one colony. Destroying the Alpha Relay bought the galaxy several month but imagine being Shepard anyway. Imagine having to choose between killing 300.000 innocent or dooming the ''entire galaxy'' to a Reaper invasion they haven't even begun to prepare for. Especially for a Paragon Shepard who tries to always save the innocent this a nightmare. Watching the system disappear from the galaxy map is...chilling, to say the least.

* A minor one from the Shadow Broker DLC: while you're traversing the outside of the Broker's ship, you can use biotics to fling the opposing mercenaries high enough that the tremendous winds catch them and blow them clear of the ship, at which point they're not your problem anymore. Of course, they're no longer your problem because ''you just threw them off a ship in the upper atmosphere'', leaving them to fall all the way to the planet's surface. And if they somehow survived that, Liara notes that [[DeathWorld the planet's environment is so hostile that the seas boil during the day, and snap-freeze just after sundown.]]

*** The enhanced graphics in the Legendary Edition make it even ''worse''. The wires holding his eyes open are now clearly digging into his flesh enough to cause bleeding from his eyes, and his eyes are so bloodshot he appears to be ''blind''.

** In fact, he escaped, [[UngratefulBastard killing the people who rescued him]] who "didn't weapons check (him) well enough". He then broke into a family's home to send his message to Shepard, and states that [[FridgeHorror the family is about to come home, find said serial killer in their house and then]] "[[KillEmAll It's showtime!]]"
* Purgatory itself qualifies as Nightmare Fuel. A HellholePrison if ever there was one. In fact, the presence of Jack implies that there could be other female prisoners in Purgatory though the only ones seen are male, [[FridgeHorror and you know what would most likely happen if a sex-deprived, psychopathic inmate ran into a weaker prisoner of their preferred gender]].

** If you speak to one of the prisoners before moving to out-processing, he pretty much confirms the FridgeHorror mentioned above. He comments that everyone there is out for your stuff. "''Your smokes, your clothes, your...''''[[PrisonRape pride.]]''" He even looks away and closes his eyes for a moment as he says that last one, then mentions that he hasn't gone to the shower in weeks. Apparently, the kind of depraved psychos they have locked up on this ship don't care what or ''who'' they take. And then there's the fact that as soon as he finds out Jack is supposed to leave with you, he ''immediately'' backs up on his earlier request to leave with you, making it clear he doesn't want to go ''anywhere'' that Jack is going. Jack is just ''that'' scary to the other prisoners.

** There's also the incredibly ominous music that plays while you're wandering around her apartment, and the foreboding talks about death she gives while you examine your things. She also asks you to pledge yourself to her as she starts the meld, and going by the dialogue wheel you can't resist her without an extremely high Paragon or Renegade score. [[FridgeHorror which would've meant Shepard's permanent death if Samara hadn't showed up]]. The fact that you're completely unarmed for this mission makes you feel that even Shepard, Badass Extraordinaire isn't going to make it out of this one.[[note]]Breaking her hold with a special interrupt, however, with the Renegade version essentially being, "Bitch, ''please''" turns it into an CMOA.[[/note]]

* In Samara's loyalty quest, you have to hunt down Morinth, an [[BlackWidow Ardat-Yakshi]], an asari that kills her partner when they [[IsThatWhatTheyreCallingItNow meld]]. Shepard acts as the [[HoneyTrap bait, and goes to her apartment alone]]. Just before she gets ready to do the deed with them, her eyes turn black and the lighting is distorted. Asari eyes always turn black when melding, which has always been a bit creepy, but when you know that the asari is getting ready to ''kill'' you, it is absolutely terrifying.

** The whole thing is creepy as hell, but it all goes UpToEleven [[https://www.youtube.com/watch?v=zp-Z69NHlHM when]] you touch the console, glow green, and are sucked into what is pretty much the Matrix, while your companions frantically try to pry open the now-sealed doors. You then find out the REAL story behind the VI (The VI is actually Gavin's brother, David, turned into a WetwareCPU against his will), topped off with a hearty helping of BodyHorror. You know Gavin is really bad when the ''Paragon'' interrupt is to pistol-whip him.

*** Rogue VI: [unintelligible sounds] = "''QUIET, PLEASE!'' '''MAKE IT STOP!'''"

** Remember the face in the last level? It's STARING AT YOU THE WHOLE TIME. Also, those security cameras with the green lights? That's the VI watching you for the entire mission.
** Try reusing the elevator when you get to the bottom. The doors open, and the elevator's ''gone''. The VI says something like, "Brakes not responding," and the elevator slams down the shaft and shatters. And it's never stated, but subtly implied - you are now trapped in an underground facility, with no communications, at the mercy of an insane VI.

** This is also similar to what Saren did in the first book and framed Anderson for. Do this and you are NotSoDifferent from him.

* Thane's PhotographicMemory, specifically the flashes of light and the look of his eyes. And not just his appearance as he lapses into one of his memories; the very idea that he can just immerse himself in one of them so easily. As he explains, you can find yourself in happy memories, or you might find yourself recalling an injury, like your knee getting shot, feeling that pain, seeing the damage all over again. At least in such cases, you can just look at the current state of your body to release yourself from that memory's grip, but to think that at any moment, if you were in some bizarre masochistic mood, without warning, your mind finds itself back in that moment of excruciating pain... Imagine if you had more negative experiences than positive ones. You probably don't need to torture drell all that much; just inflict enough pain enough times, and their own minds will finish the job for you.

* Failing Joker's mini-mission near the end of the main story. [[spoiler: Joker gets spotted by a Scion, panics, and falls down. You're then treated to a close-up shot of the Scion from Joker's perspective before a massive hulking claw reaches towards you, followed by a gasp from Joker and a Game Over screen. You get another one if you get too close to the Praetorian, which looms over Joker and opens up to show him the husk heads, leaps at him, then you hear a gasp and a stabbing sound followed by a Game Over screen.]]

* [[VillainOverride Harbinger]], especially on Insanity difficulty. Imagine it from your character's perspective. You just finished fighting off a wave of Collector assassins on some moving platforms. Your ammo is nearly depleted and your team is exhausted, only for you to hear in a deep, flanging voice, "[[AC:I will direct this personally]]." That enemy you thought was taken care of? Its flesh starts sloughing off and its body glows with yellow light. You shoot at it, but the shields are too strong. Harbinger hurls a supremely powerful biotic singularity at you, enough to rip through your shields just as you take cover, and while you take him out moments later with seconds to spare...you hear his voice, again, from across the room. He's coming for you. He's tougher than anything you've EVER fought, and he'll ''never,'' '''''ever''''' stop coming. Until you're dead. Worse still are some of his lines when you kill his current body, just reaffirming how utterly unstoppable he is. Like [[AC:'''"I WILL FIND YOU AGAIN."''']]

* Prisoner 403. "I can hear the screaming in my head...it's nice." The obvious assumption is that the dude is mentally unstable. Except this is ''Franchise/MassEffect'', where there's a ''worse'' explanation for hearing voices, and who knows if he's always been nuts or if he was once a perfectly normal, sane guy who happened to be working with some kind of mining op that discovered an alien artifact...

** Every once in a while, Harbinger will taunt you as he possesses bodies to come after you, including the words
[[AC:'''"ASSUMING [DIRECT] CONTROL!"''']]

** Seeing and hearing about the damage that was done to Shepard, between being exposed to the vacuum of space, asphyxiating, and then ''an uncontrolled orbital reentry'' along with crashing into the planet. How much of the old Shepard was there before Miranda got to work? [[TheseusShipParadox How much is left at the end of the game, with all of Shepard's upgrades?]]

** The NonstandardGameOver, [[https://www.youtube.com/watch?v=ygeLJ64FxUc which shows EDI getting possessed by the VI]]

** The ending's worth mentioning. As Jacob confronts his father, Shepard notices a male, crazed, standing there like a zombie. Soon he's joined by several more. S\he points them out to the third member of the squad, who will [[LampshadeHanging lampshade]] what they will do to Jacob's father if Shepard chooses to abandon him.

** It's also another reminder of how terrifying the concept of [[AboveGoodAndEvil Spectres]] really is: you have Saren, the BigBad of the first game, who's so ruthless in getting his job done matter the cost even before he became indoctrinated, and it's implied from Samara's story that his protege Nihlus isn't that much different, then there is Tela Vasir, a Spectre who's also [[DirtyCob a double agent]] working for the Shadow Broker for valauble intels at the cost of doing whatever the Broker requires her to do, even if it means blowing up a building full of innocent people, and there is Commander Shepard him/herself, who at their worst could be as ruthless as both of them when it comes to completing their mission. And ''all of them'' are uniquely trained OneManArmy PersonOfMassDestruction capable of tearing through ''anything'' the galaxy could've thrown at them - moralities be damend, and they ''will'' get away with it all because they're above the law.
