I have ‘Studied’ horror psychology for quite some time now a lot of videos made by Extra Credits is a very good place to look this will be a lot of good tips for psychological horror. My main tips is to learn the ‘tension and release cycle’ as well as the ‘uncanny valley’ I do not wish to explain these here but a simple google search should be able to help you. Another tip I have is to not make the game so open what makes players feel panicked is when you take away their control if I have a huge open room with 5 zombies in it the player will walk around the zombies but if I had a narrow corridor with 5 zombies it forces the player to fight them. That’s some quick tips sorry for this being so unorganized and messy I hope this has some understanding, I might drop a tutorial on the dev forum going very in-depth. DM me if you got further questions or reply here.
Everybody hates rats and bats, so don’t make them impossibly annoying…
In general Roblox games never have enough graphics sound and FX. Lag is caused by bad code; not graphics… Gamesare supposed to be eye-candy…!
I feel like a game that has black figures with red eyes following you and… basically almost all you listed above that’s actually pretty good is Identity Fraud. Kinda perfects that eerie feel, even with all those things. But yeah, I can’t say I disagree with this.
I like horror games that genuinely horrify you. For example, being stuck in an building of which you THINK something is after you > a building where you constantly run away from something and if you get caught you get jumpscared and have to restart
Phasmophobia is a spooky game cause of the vibes. If you die, you only lose your items, and it doesn’t jumpscare you. However, Phasmo is only spooky, whereas a game that is more creepy and the outcome unknown, that would be a scary game.
So here’s what bothers me…
Horror games that try to scare players with only spooky sounds/music, lessened lighting quality, and jumpscares. Like dude, that’s A) not a very immersive experience, and B) far too common. Your game has to be more creative than what I’ve described if you’re going to keep my attention and interest.
- Games that require you to find a key are fine, but when the key is in a room that’s about 500 studs by 2000 studs with 10 stud black fog, it’s a problem.
- Games with jumpscares that have seemingly no tie to why the player was jumpscared. For instance, if I’m walking down a hallway and I’m jumpscared, I expect to have lost the game/for a major plot point to occur, not to just continue walking as if nothing happened.
I really hate games that rely to heavily on jump scares. While jump scares can be used effectively so many games rely on spawning a deformed avatar in front of you and then playing annoyingly loud, distorted audio.
In addition, it feels like lots of horror games are also reliant on the fact that their entity is twisted, stretched, and baked to bizarre proportions. Instead of making good, steady, horror that builds up pressure they rely on thrusting a human face that’s been stretched out disproportionately with the scale tool in front of you while playing a loud bang.
I also hate it when horror games in Roblox are so dark that it’s really hard to see anything. Darkness is of course natural and good to have in a horror game but so many games are so dark that you can barely see.
So right now, horror on Roblox is (for the most part) not actually scary, just startling.
I’m currently trying to create good horror in my own game by building up pressure on the players as they race to complete their tasks before the entity strikes again. Sound Design and lighting are also hugely important and will play a key role in building tension and suspense.
Hope this helps

Yeah I agree, I watched the Tomorrow War once(which probably isn’t classified as horror but still creepy at times), and the spookiness of what was after the people was when you didn’t know what it was, after you did know, it was a lot easier.
