Nightmare Fuel: Dead Space 3
Isaac and John Carver investigating an abandoned ship, filled to the brim with coffins. Isaac mentions earlier how it looks like a funeral and Carver points out that the deaths were executions based on where the blood splattered. And then, as if on cue, dozens of Necromorphs attack.
The Necromorphs of the abandoned flotilla all by themselves. 200 years of waiting around doing nothing does interesting things to a Necromorph's biology and appearance, as they're more mummies than zombies by this point. Their dried-up and often-missing flesh somehow makes them even more revolting than the fresh-meat Necromorphs you deal with in the previous games.
The characters think that this was the Admiral leaving a clue to stop the Markers. It's actually a command/plea from a necromorph the size of a moon, speaking through the Markers right into the Admiral's head.
The new Feeder enemy subtype is chock full of terror. These are necromorphs that are formed when a person eats necromorph flesh. Whether out of desperation or Unitologist fanaticism, it doesn't matter- it's still terrifying. And disgusting.
Here's the most terrifying thing about the Feeders: THEY AREN'T DEAD! Recordings indicate that the Feeder transformation is much more a mental one than a physical one. Eating necromorph flesh makes your mind into that of a cannibal, and turns the person into a creature that can starve and starve, but never die of hunger. They are constantly hungry, but never die. We hear recordings made by those who succumbed to the transformation, and they were, 200 years ago, still capable of speech. But after 200 years with no food save humans and dead necromorphs, they are completely mad with hunger beyond all possible reason. This is why they are now a Fragile Speedster enemy: their bodies are still living, but just barely on the verge of life and death.
One audio log from a soldier mentions how not only did he know some of the Feeders attacking his base, but when he looked into their eyes they seemed, for a moment, to recognize him as well.
In one of the optional missions, you end up in a room with about 5 Regenerators... Thank God none of them broke out. Until three of them appeared to ambush you as you walk Isaac out of that mission.
The wasters. Just the way they walk up to you muttering unintelligible things while trying to kill you.
An entire civilization is consumed in the creation of a single Brethren Moon. Now, how many moons are there?
The entire DLC counts as this. The developers said that Awakened was intended from the start to hark back to the terror of the first 2 games, and even surpass it.
With 3 chapters chock full of Mind Rape, Body Horror and self-mutilation, they succeed to quite an extent. And you thought the Necromorphs were scary.
For starters, the main menace of the game: a Necromorph-worshiping Unitologist cult, a cult hit with a final, pure dementia signal from the fallen moon right before its demise. The insanity of the cult as a result is so horrific and ungodly that even devout Unitologists think they are batshit insane. One Unitologist, who had already witnessed all the horror of the main game and maintained his religious beliefs, outright lost his faith upon witnessing the cult for himself.
Their main religious practice is the main source of the terror. They cut off pieces of their body voluntarily as a mad symbolic offering of dead flesh to the Necromorph moons. That isn't even the worst part: they use their body parts to decorate the ship. They string up their dismembered limbs on strings like Christmas lights. At one point, you discover mini towers made up of human hands made to hold candles.
The ending. The Brother Moons are attacking/devouring Earth now. For the first time, it appears that Isaac has outright lost.
Not an exaggeration. Unless there is a sequel, humanity is literally done for. Even after the desperate struggle against the Necromorph scourge of the last 4 years of games, books, and movies, The Bad Guy Wins. This really is the darkest the series has gotten.
"They are hungry. They are coming."
I'll do you one better:"We are here."
The combined moons emit a signal strong enough that it can make pretty much anyone insane, even from light years away. They can move so fast that they can even outrun shockpoint drives. There is no way of escaping them. Just their active presence in the galaxy can destroy civilization. So unless there is an actual sequel or a new dlc release, it's game over. The bad guys have won. There is absolutely nothing out there that can stop them.
