I’d recommend Control by Remedy. It’s got some SCP vibe and has liminal spaces, spooky supernatural shit and great looking environments and game play.

Subnautica has some creepy overtones.

Outer Wilds. It’s better to play it without knowing much beforehand. All I’m gonna say is: it will make you feel very lonely and even vulnerable at times, although it’s not a horror game by any means. It’s a beautiful videogame with a mind-blowing story.

I’d say Arkane’s Prey hits that for me. The feeling of isolation, not only on the station, but by virtue of being in space, and the story itself. The mechanics of the mimic enemies can create emergent jump scares, but I’d definitely say it’s not a horror game.

I’d also say Death Stranding, at times. While the human NPCs are very wholesome, the atmosphere and experience of delivering the packages out through the timefallen wasteland and that isolation lends itself well to introspection and the BTs are pretty creepy and axiety-inducing until you’re used to them and can fight them.

Half Life/Black Mesa. I replayed it recently and I had forgotten the level of unease that pervades most of it. While short of horror, there’s been an obvious disaster, people are panicking, and it’s unclear to the PC what is going on for most of the game.

• Bloodborne

• Control (definitely what you’re looking for)

• The Last of Us

• Little Nightmares (quite similar to Inside, horror-inspired and creepy but barely any jump scares)

• Inscryption

• Dying Light (admittedly not very scary, but at night where you get chased by creatures can be very intense)

Control does a good job of starting out uncomfortable and weird, and continuing to escalate as the story progresses. A great deal of unease since you don’t understand what’s going on with your character or the environment she finds herself in.

Subnautica is not a horror game, and was not intended to be scary; and yet the way it captures the dark, oppressive nature of deep waters makes it an extremely terrifying experience.

Hollow Knight

What Remains of Edith Finch. It’s not horror at all but you’re the last person alive in your family, exploring your childhood home, which is a crazy house with tons of weird add-ons and secret passages, exploring how your family members died. Mental illness, insane unlucky accidents, all that. It’s a really truly excellent game. It’s unsettling in a way that keeps you on edge without ever being actually afraid

I’m surprised I haven’t seen Morrowind in the comments yet. The storytelling gave me the impression that Todd Howard must’ve played a lot of DND campaigns while under the influence of psychedelics just to lay the setting for the plot. I highly recommend because I’ve had a lot of moments throughout my playthrough asking myself “wait, did that actually happen?” And, “Is this a Bethesda bug, or is the game straight up cursed?”. Also, Many of the characters, creatures, and a certain “house”, or faction in the game are straight up Lovecraftian, with aesthetics pretty on par with Bekzinski’s art-style. I also think the Marathon series fits the bill on a lot of these aspects. It’s Bungie’s precursor to Halo, and while its narrative may be similar, I think the devs had to get creative with the limited software capabilities available at the time and so the narrative ended up being an experience I’d describe as “wild and uncanny”.

I’ve been playing DREDGE and it definitely has the creepy element down. It’s gotten me hooked for sure

Signal Simulator is a game about being completely alone in a base in the desert doing science stuff in search of aliens. It’s not really horror but there’s plenty of uneasy stuff in it.

There’s also a newer game inspired by it called Voices of the Void which is more actively developed. Technically, it’s not horror but the developer likes to fuck with you in all kinds of ways.

The world of Scorn felt pretty alien and unnerving.

GMOD.

Something about Source engine maps set in realistic locations devoid of anything but a player has an overpowering creepy, liminal space vibe.
