Nightmare Fuel: Watch_Dogs
Aiden. A man who with the touch of a button can turn the entire city into a weapon aimed directly at you. Imagine what's going through the heads of the mooks as fuseboxes explode in their face, their com-systems either refuse to work or let out a sudden, earsplitting burst of static leaving them reeling in agony, and grenades activate on their belts leaving them scrambling to get free: they must think they're up against some kind of murderous poltergeist.
All this coming from his obsession at protecting his family to the point of borderline Sociopathic Hero.
Dermot Quinn's introduction is chilling. Even worse when you consider the fact he ordered the hit on Aiden. He just went up to the man whose life he ruined and thanked him for his work.
The "Alone" digital trip is surprisingly unnerving for being a simple modification to the game's rules. Eerie robots with flashlights for heads searching you in a bleak, deserted Chicago—somehow, it works.
It's a particularly jarring experience since the game focuses on the player character's connections to the millions of people around him , and these people are entirely absent, their existence only hinted about by dozens of damaged cars laying around and confiscated weapons left around the city.
The Auction, where girls from around the world are sold off into slavery. They're drugged up to the point they can't remember their own name and their profiles are just names and numbers when you scan them in the Profiler. Aidan is clearly horrified by what he sees there, and vows to hunt down everyone who evaded the police raid Aidan sent on them.
The Randomizer camera feed videos you can be even more abrupt, especially since you can find them in bunches when hacking a new ctOS station.
Just walk around with your Proflier on and see how many crimes occurred in Watch_Dogs' version of Chicago for yourself...
Several ctznOS Randomizer vids are amusing like the one of the father criticizing his son's game of Assassin's Creed everyone likes to talk about, but some are definitely at this end of the spectrum:
One is a clusterfuck of weird glitching, as if a real person were experiencing videogame clipping errors, complete with messed up sound. After a few seconds, ctOS gives up and reboots the camera.
A man humming to himself happily while placing a severed hand on a table. Because the videos are heavily stylized its impossible to tell if it's a real hand at first, but the scanner is able to identify it as belonging to a missing person. The man cuts the fingers off the hand, uses them to make cocktail sausage, and walks away eating one.
Bellwether, which allows someone to use ctOS to influence the general population via data and media manipulation. It's used to get Mayor Rushmore elected. It's later used to get Rushmore to come to the conclusion that his wife is cheating on him, prompting him to divorce her.
There's even hints in the audio logs that show it learning things on its own. In short, Bellwether could be an AI!
The Hanging Woman, The Dead Grandfather on the floor, The man putting a pistol in his mouth and pulling the trigger Privacy Invasion videos also are horrifying.
From the ending; Evidently, even pacemakers are connected to ctOS and can be remotely shut down.
