- The first reveal of the Mimic. You go through a series of tests where you are in a sealed off exam room while scientists on the other side of a window observe you. In the last room, you sit down to take a personality quiz while the lead scientist asks someone to get him some coffee. He gets his coffee as you finish the quiz, and then he invites you to take an Inkblot Test. If you look down at the test right away, it's easy to miss the Mimic crawling up the scientist's desk and turning into a new coffee cup. Your first warning that anything is amiss might be the scientist expressing confusion about his coffee cup suddenly being empty, and then all hell breaks loose.
- You find yourself at the start of the game again, except everything is just a little bit wrong. The soundtrack has taken an ominous tone, the phone doesn't go off with your wakeup call from Alex, the date on the clock is different, everything is in different places, and if you check your email again, you just have a bunch of identical messages from someone named January saying only "DANGER. LEAVE NOW." Oh, and if you step out into the hallway, the repair lady you could talk to at the start of the game is now lying dead in the corridor. Did we mention the far end of the hallway is now closed off, effectively trapping you in your apartment?
- Prior to getting the psychoscope and mimic-detection chipset, mimics are a constant source of Paranoia Fuel. Pretty much anything from chairs and tables to loose papers could turn out to be a mimic, and if you miss even one, there's every possibility that it will crawl up behind you and finish you off when you least expect it.
- To make matters worse, Greater Mimics can't be detected even with that chipset unless you get the advanced version much later in the game. Which you may or may not even find. You thought you were safe, but you're not.
- Some scripted mimics are far more clever than they have any right to be. In the Holding Cell right off the Security Office, there are two chairs - one that a corpse is sitting on, and one askew in the corner. Care to guess which one doesn't belong? You'd be wrong.
- Calibrating the looking glass in Psychotronics leads to a phantom showing up behind the glass in a scripted Jump Scare. At least it can't hurt you. The phantom that spawns at the top of the stairs afterward, on the other hand...
- Poltergeists are incredibly creepy. They're rare enough that you don't have the luxury of getting used to them, so every time doors start slamming open and closed and the lights flicker you get those wonderful few moments of panic as you try to find the source. They're also invisible most of the time, so you can't use stealth to scope out the room and find them before they notice you. And on the rare occasion that you do catch a glimpse of them, they look like severed torsos dragging themselves across the ground with their arms. Not pleasant.
- Every time Morgan uses a Neuromod, it turns his eye red. In the trailer, it progressively turns his eye redder and redder, almost like watching a drug addiction (via inserted in the eyes) gradually grow. The third time, it borders on Uncanny Valley.
- The arrival of the Apex is incredibly unnerving. It's so huge that it blots out all the stars around the station, and the first real glimpse you get is of what seems to be its head and multiple bright white eyes glaring at you through the glass of the Arboretum. Many a player could be forgiven for hightailing it out of there.
- Trying to scan the Apex with the Psychoscope results in your health being reduced to 1, your Psi totally draining, and the Fear effect. Even to Morgan, it's completely alien.
- The first time you approach the greenhouse in the Arboretum, a crew member bangs on the window next to the door and begs you to open it, which you most likely can't do at that point, as a Telepath floats down behind him and takes over his mind.
- Every employee on the station has a tracking bracelet, including the cook, Will Mitchell. His tracking bracelet is found in the kitchen... inside a box of suspicious meat.
- When Morgan catches up with Danielle Sho, she's outside the station in an EVA suit and beginning to run out of oxygen. From Morgan's own spacewalks, we know that the oxygen tanks built into the suits have an impressively long lifespan; from the various notes left around Talos I, we know that the Typhon outbreak began around three weeks before the events of the game. It's not clear exactly when Danielle decided to save herself with an EVA, but since she's one of the last survivors of the station, presumably she got out pretty early on. So has Danielle been clinging to the side of the station, relying on her suit's life support systems to keep her from suffocating or dehydrating, waiting for her murdered girlfriend to give her some sign of life... for the best part of a month?
- Aboard the station is Luka Golubkin, "Volunteer 37", a convicted murderer from Russia who was being used for experimentation by Morgan. An email reveals that a Typhon Telepath not only refused to enter his mind, but developed an aversion to him. He's still alive on the station and very mad.
- In the Mooncrash DLC, we finally get to see what being controlled by a telepath looks like from the perspective of the victim. Andrius Alekna gets controlled at the start of his story. The creature uses the voice of his own son, and repeatedly tell him "It's what you want". By all accounts, Andrius is still aware of what he's doing, but now there's a voice inside of him that feeds on his guilt and love to convince him that he really wants to do things he otherwise wouldn't. And the cherry on top? The telepath kills him the moment he's not needed anymore, and he's probably just doomed the entire earth.
- How Joan's personal quest ("A Little Bird Told Me") begins - with Joan hitting a man in the head with her wrench hard enough that it not only kills him, but leaves the wrench stuck in his eye socket.
- Riley Yu's way out of the facility is an example of this. Not only she gets her consciousness uploaded to a machine and her body killed, which is scary by itself; the machine gets captured by a hostile company and used to violate Transtar's secrets on the moonbase experiments, with Riley unable to do do anything about it.
