History NightmareFuel / BrutalDoom

** Former Human: Tackling and repeatedly beating his skull until there's nothing left, eviscerating him as he screams in agony with his guts coming out of his abdomen, tearing him in half, being thrown into the ground before getting his skull gets repeatedly bashed with his own assault rifle or [[TearOffYourFace ripping his entire face off with skin and all]].

** Shotgunner: Ripping his head off, snatching his shotgun before blasting his chest off sky-high or ripping his arm off before being torn apart.
** Chaingunner: Throwing him into the ground, then jumping on its back before ripping his arms out before dying from blood loss or tear him in half.

** Chaingunner: Tearing them in half, or throwing them to the ground and ripping their arms off before leaving them to bleed out. They scream for a minute before this happens.
** Shotgunners: Either the good old ripping off his head from his body, tearing him limb from limb, or snatching his shotgun, then shoving the barrel into his chest (without anything to act as a bayonet), propping him up into the air, and then blasting a new hole through his heart and back.

* Let's take a look at some of the fatalities, shall we? As much as they're awesome, they're certainly unnerving especially in the Version 21.

** Just as bad, imagine going through a place like "E1M2 - Nuclear Plant"'s maze and hearing enemies say "I smell fear..." or "I smell human..." as you get near to them, then scream "FLESH!" or "Hell awaits you!" when you enter their line of sight. Occasionally, when active but out of your line of sight, they'll mutter "Sector clear..." giving the impression that they're ''hunting you.''

** Imp: Throwing them to the ground before crushing their skull under your boot, ripping their heart out with your bare hands, knocking them down and then punching them in the face until you crush their skull.
** Cacodemons: Grabbing their upper jaw before heaving upwards to tear them vertically in half, or ripping out their single eye.

** Mancubus & Arch-Vile: Total immolation with hellfire, making you wail miserably as your body flails and convulses in excruciating pain.

* The scream Doomguy lets out if he dies from standing in a hazardous substance is very disturbing to say the least.
* One of the Brutal Doom Mutator side-mods changes the zombified soldiers' grunts and snarls with voice samples, often saying things to antagonise the player. Now imagine hearing things like "[[ParanoiaFuel You will not escape!]]" just when you quit the game from main menu.
** Just as bad, imagine going through a place like the maze in "Nuclear Plant", E1 M2, and hear enemies say "I smell fear..." or "I smell human..." as you get near to them, then scream "FLESH!" or "Hell awaits you!" when you enter their line of sight. Occasionally, when active but out of line of sight, they'll mutter "Sector clear..." giving the impression that they're ''hunting you.''
** And that same mod allow imps to crawl on the ceiling to hunt you. Each growl you hear, you'll start looking up frequently.

** Arachnotron: Ripping off one of their mech's legs and smashing it into their head, or tearing them out of it. The latter will have them screaming and desperately trying to crawl away despite clearly bleeding out, and will either die on their own or can be smashed to paste by your fists or bullets.

** Mancubus & Arch Vile: Total immolation with hellfire, making you wail miserably as your body flails and convulses in excruciating pain.

*** The giant red cyberdemon in the tower is similar to the boss at the end of episode 2, but he has two rocket launchers and can spit fire.

* Sometimes a well-place hit will blow off limbs. Sometimes [[NightmareRetardant this is comical, like an imp hopping around uselessly on one leg.]] Sometimes it's a bit morbid, like enemies crawling around or otherwise incapacitated, screaming their little heads off. But it's more unsettling when that isn't enough to stop them. [[DefiantToTheEnd Revenants might be left crawling after you and still firing rockets, zombies might draw a sidearm after you render their weapon hand useless, etc. For added fun, regular demons that lose an arm will stand there stunned for a moment. They might be out of the fight, or they might continue charging after you shortly afterwards]].

Oh, you think ''NightmareFuel/{{Doom}}'' has too much NightmareFuel? Bad news, this mod will offer even more nightmare to point where the original DOOM would look like Super Mario Bros.

* The fatalities on the player really drive home how [[OhCrap utterly screwed]] you were the moment you stepped out of that fateful hangar in how humiliating they are:

** Mancubus: Ripping open their guts and leaving them slumped to their knees, groaning in pain as their entrails fall out.

*** Instead of two Barons of Hell at the end of the first episode, you fight two centaur-like demons who fling green explosive BFG-like blasts at you.

*** The Guardian (which is Korax from ''Videogame/Hexen'') guarding the portal between the city and Hell rains fire on you from above.

* Some of the levels from the Starter Pack that came with Brutal Doom v20 are downright terrifying and push the Doom engine to its limits. In particular is "Sacrificial Grounds", a bona fide ''demonic concentration camp'' which features captured marines chained up and mutilated, screaming in agony as if they're begging you to put them out of their misery. Even though a certain variation uses the [[VideoGame/HalfLife2 Headcrab Zombie sounds from Half-Life 2 in order to make it even more disturbing.]] The music, carried over from ''Doom 64'', is also punctuated with [[HellIsThatNoise low sorrowful moans and crying]].
