Saint of Chains (NEW)
Release Date: 12 May, 2026
Published by: MystiveDev LLC
Saint of Chains is a retro survival horror FPS – think somewhere between Silent Hill 3, Condemned, and Cry of Fear. You play as a workaholic father searching for his wife and kid, armed with whatever’s nearby and running low on ammo. The monsters you’ll face aren’t random. They’re grief, guilt, isolation, and anxiety wearing skin. The dark isn’t the worst thing here. The truth is.
Chasmal Fear
Release Date: 17 Apr, 2025
Published by: Wandering Wizard / Snail Games USA
Chasmal Fear is a first-person tactical shooter survival horror game that puts players in a mysteriously empty sci-fi underwater facility where something has gone terribly wrong. You’re watching this through a bodycam. The facility is empty, but there’s something in the depths. Solo or co-op – though having a friend beside you doesn’t make the depths any less terrifying. It just means something else knows where you are.
Mirror Forge
Release Date: 6 Dec, 2022
Published by: DreadXP
Mirror Forge is a first-person psychological horror game built around alternate dimensions, worlds layered beneath this one, darker and alive. Solve puzzles. Survive things that don’t follow normal rules. And try to hold onto reality when it starts bending around you.

the Wrong House

Wipe: Toilet Plague
Release Date: 1 May, 2020

Alan Sharp
Release Date: 23 May, 2021
Published by: Mystive Studios
Alan Sharp is a detective who sees things he can’t explain. And he can’t stop looking. A mystery-horror game built around investigation, open-world exploration, and the slow creep of something deeply wrong. Investigate an utterly bizarre homicide filled with supernatural elements, solve puzzles, and survive the various monsters that slumber in the dark.
About Us
MystiveDev is two brothers who grew up scared of the dark and never really got over it.
We started out contributing to projects like Alan Sharp and Wipe: Toilet Plague, learning the craft, figuring out what kind of games we actually wanted to make. That answer was always the same: horror. Atmospheric, story-driven, get-under-your-skin horror.
Our first real swing was Mirror Forge, published by DreadXP. A psychological descent into alternate dimensions and the kind of darkness you can’t quite name. Then came Santa Fell in the Wrong House, because even at Christmas, we can’t help ourselves.
Chasmal Fear was our biggest challenge yet. A sci-fi bodycam horror game, built in Unreal Engine 5, published by Wandering Wizard. Mutating creatures. Flooded corridors. A co-op experience designed to make you trust your teammate and then immediately question that decision.
Now we’re working on Saint of Chains, a retro FPS where every monster is a fear wearing a face. Loss. Guilt. Isolation. Anxiety. It’s the most personal thing we’ve made.
We’re a small studio. Two people, one shared obsession, and a long list of games we still want to make. If you’re a publisher, journalist, or fellow dev who wants to talk, we’d genuinely love to hear from you.
