As a game where anyone could do just about anything, Garry's Mod is known for creating some very disturbing stuff.
The base game
- Sometimes, turning up the sensitivity of the Face Poser allows you to make some extremely disturbing expressions. Case◊ in point◊.
- Similarly, for GMod 13, Garry removed the restrictions on facial muscle animation, and added some more ways of manipulating bones. This essentially allows the player to make any kind of Humanoid Abomination they'd like out of the NPCs they have installed. Hoo boy, are the results genuinely terrifying.
Mods
- The blood effect mod Real Life Blood MOD is Exactly What It Says on the Tin, where it is blood decals that are based off of real blood splatters from actual forensics pictures. The thumbnailspoiler doesn't help matters either.
- The Perfectly Harmless Companion Cube. At first, it seems to be a regular Companion Cube from Portal...but when you turn around, you'll notice it's moved closer. Look away for too long, and it'll creep up on you, before pulling out a knife and stabbing you to death. It's even worse if you've lost it.
- Alternatively, there's mods that offer the weeping angels and SCP-173.
- Whenever a Nextbot isn't some 2D picture of a meme or Narmy creepypasta character, it can be scary to know that you are in the same map as a predator that always knows where you are, is faster than you, is actively trying to murder you, and the only way you could defend yourself is by trying to lose it in labyrinths, and even that's not guaranteed to save you.
Maps
- The classic map gm_Shambles is a good example of a creepy map. It is an old abandoned British neighbourhood at night with faint fog. It has only a few enterable houses and they are all missing their furniture, and all of their doors are either missing or knocked down. Some windows are boarded up, some rooms have only a few lights on, some houses have been damaged and some houses even have splatters of blood. There is also a creepy ambience throughout that sounds like a very faint drone and sometimes, church bells may ring... It leaves little to no evidence of what kind of apocalypse had actually happened here, but the only clue of '"what"' may have happened is a small newspaper left on the floor of one of the living rooms of a house. There are also some disturbing Easter Eggs around the map, with an example being a well that has a gnome in a middle of a pentagram at the bottom. All of this results in a map so creepy that sometimes some players are not even able to explore the map fully.
- it is also a bit depressing to go through the map, as it's original creator Fartomaticatron died in January 2015.
- The daytime version isn't any better.
- If that's not bad enough, some Trolling Creator decided to make a haunted version of the map, where there are black shadow people that are scripted to appear every once in a while. Have fun!
- Night Paranoia, an open-ended and dynamic horror map which involves the player being required to survive a home invasion by a solo Civil Protection unit. It is very intense to experience, as the player is required to use stealth just to survive. there are ten Multiple Endings, and being spotted can result in a Jump Scare courtesy of a very loud Scare Chord, which could be triggered at any moment...
- In a way, it also makes the Civil Protection a lot more menacing.
