- The fate of Isidor. When you finally get access to his room, it looks like he exploded from the inside out and painted the walls with his organs. This is when you realize the plague is far worse than anyone could have thought.
- Those terminally infected by the Sand Plague are often wrapped in thick, burlap robes. Meaning we have no idea what they look like under their clothes, but it's guaranteed to be absolutely horrifying considering the plague covers houses with Meat Moss. While you at first feel awful for them, it quickly becomes apparent that they are trying to intentionally infect you.
- The Albino, a mysterious Steppe entity who is said to be an embodiment of the Plague itself. Simply standing near him erodes your immunity and infects you, and he his proportions are nothing short of terrifying.
- The first sign that the Plague is not any mundane disease is that the clouds of it's germs form into screaming, tortured faces, or in advanced stages, the Grim Reaper.
- You know what's absolutely terrifying in that game? The infected districts. The unnerving music that starts playing, the men and women in cloaks stumbling around, the scab-like growths on the houses, the children writhing in pain...but worst of all are the houses in the districts. Dilapidated green walls, and you can only stay there for a limited time because the fog that occurs in the streets that makes you ill happens inside too, but now it's chasing after you. Sometimes, deep in the house, you will find people in the fetal position, unresponsive or weeping. Other times they are deserted, resulting in a good amount of Nothing Is Scarier. When they're NOT deserted, creepy marauders clad in black are trying to kill you. They jump right the hell out of nowhere, so it's even worse.
- Oh gods, the infected houses. Not only is there everything in the above paragraph, but the rooms are so claustrophobic and the clouds are so fast that just going in is extraordinarily stressful.
- Compounding it, there is no logical reason for the houses to look the way they do. Furniture has been thrown around like a tornado had just ripped through the building, despite the infected being barely able to move let alone rip shelves off walls. Blood is splattered everywhere, and it seems like the entire house is rotting like a piece of meat.
- The worst part of Pathologic is simply the creepy juxtaposition of supernatural, surreal horror in an otherwise realistic setting. It's just so extremely unnatural and wrong, and evokes strong feelings of how this should not be happening. Plus there's the Psychological Horror aspect of how people realistically react to such a supernatural and nebulous foe...
- The use of the first-person perspective breeds tons of nightmare fuel on its own, due to you not having any peripheral vision. There could be a disease cloud right next to you and you won't know it until you either turn the camera or it's right upon you. And of course, there's always the fun game of guessing what's going to be in store for you when you turn around...
- The bad ending. Just...the sickening montage of the town itself literally rotting from within due to the plague, the images of the diseased people lying in the streets (including a child)...it's a pretty big incentive to not screw up during the main game. Oh, and speaking of which, while you watch, you know that it's your fault for failing to save your Adherents or being unable to make a choice during the final council.
- The Kickstarter video. The burning pyres, the utterly still Tragedian resembling a standing corpse, and the fact the devs speech to you is from the perspective of them cutting you open and tossing out random bits, which include a heart, what appears to be your spinal cord, and... a rock, which they just drop in the plate without commenting on it. Combined with the eerie speeches about the Sand Plague and eternity bleeding into the ground, it is probably one of the most eerie Kickstarter videos ever made.
