I was a wee lad, but the Butcher in Diablo 1 always got my heart going. “Ahh, fresh meat..”

There was an 3d fps Aliens game (I think AvP 1) that scared the pants off me. Playing that game and having the aliens running across all surfaces out of nowhere was too tense for me. It actually ruined horror gaming for me for a long time because nothing else seemed scary after playing that.

It’s probably always going to be Alien Isolation’s Xenomorph for me

For me it's kind of hard to say. The Groom from Outlast really stuck with me a long time, but I think P.T.'s Lisa is the one I think of first when I think of scary

The Pinkies/Piggies/Demons from Doom and Doom II. I guess Doom qualifies as a horror game? Buy yeah, after playing a lot of Doom as a kid, I had a nightmare on Christmas eve that the pig demons ate Santa.

I'm thinking about replaying RE4 VR. Went through it once - first time playing the game - and had a blast, but there's one enemy type that's really making me reconsider: the snakes that sometimes jump out of boxes. Brrrr!

The green, reptilian monsters that replace standard zombies later in Resident Evil 1 called Hunters... Those things jumping out of nowhere were crazy!

I don't know about the most, but I think the Girl in Resident Evil Requiem was the most recent one that got me. I know the Uktena in Uktena 64 got me the first time I played it. I want to say the Anglerfish in Anglerfish got me once or twice. Ooh, and the creature from FAITH Chapter 1.

Cyberdrmon from the original doom. Playing this at 2am as kid gave me occasional nightmares for years. 10/10, would recommend.

The AvP aliens and Diablo 1 Butcher are brilliant. But also would like to add two creatures from Dead Space: the wall snake, and the one who regenerates. ::: spoiler Motivation/spoilers The wall snake is more of a surprise. But it is such a great setup. You walk into a corridor and you see a hole in the wall. You are very careful not to take your eyes off it. Then you exit, nothing happened. You ho on, do some other stuff, and you have forgotten all about it. Then bam you opened the door to the corridor but forgot about it, a snake grabs you and throws you arround, and you realize where you are.

And the regenerating one. Brilliant. You face it, start you usual thing, shoot the limbs, it goes down, nice. It fucking regrows its limbs?! Run! Slow it down, run, slow, run, ... :::

Alien Breed (top-down shooter) on Amiga had these insectoid queen aliens that would suddenly crawl into view and take up half the screen. Startled the shit out of me every time.

I think it was that red zombie that came back after you killed a regular zombie in the first RE (might have been just in the NGC remake).

Old lady from Visage. Don't like that peaking around corners at me nonsense.

Used to be Pyramid Head, but now that I've grown up it's the bandaged guy from Mouthwashing. More horrifying than any monster could ever be

Shivers in Vintage Story. Those things just move wrong
