A Lovecraftian survival horror RPG where your sanity is both your weakness and your only way through.
Stygian: Outer Gods is a first-person survival horror RPG from Misterial Games, published by Fulqrum Publishing. It entered Steam Early Access on April 14, 2025 and exited with a full 1.0 release on October 26, 2026. You play Jack Harrison, escorting a mysterious girl through the drowned, fog-bound city of Kingsport while hunting the truth about her family and her missing father. Scarcity is the baseline - ammunition, medicine and light are all finite - and the sanity system sits underneath everything: break down and you fight worse, hear worse and see worse, but you also unlock the dialogue, lore and puzzle routes that sanity normally keeps shut. This wiki covers the sanity mechanic, the crafting and survival systems, the Kingsport environment, and what the 1.0 release added.
Your mental state is a tracked resource with real mechanical weight. Low sanity degrades your combat, colours the sound and the picture, and quietly opens routes that a stable mind cannot reach. It is not a meter to keep topped up - it is a trade-off.
Ammo, medicine, batteries and light are all finite, and the world does not resupply generously. Every encounter is a question of whether the thing in front of you is worth the rounds it will cost.
A drowned, fog-bound city built on layered architecture and bad geometry, designed to be hard to navigate. Learning its sightlines is a genuine skill, and the map you build in your head is more useful than the one the game gives you.
Artifacts, melee weapons and firearms sit on real progression curves rather than a single upgrade tree, which means the way you solve a problem in the back half differs from how you solved it in the first hour.
Stygian: Outer Gods is a first-person survival horror RPG set in a world of Lovecraftian decay, developed by Misterial Games, a studio based in Kazakhstan, and published by Fulqrum Publishing. It entered Steam Early Access on April 14, 2025 and left it with a full 1.0 release on October 26, 2026, priced at $24.99 with a 20% launch discount.
You play Jack Harrison, a mercenary escorting a young woman named Katherine through the drowned, fog-bound city of Kingsport. The errand is to find her missing father and to understand what her family was involved in. Katherine speaks to you throughout, and a substantial part of the game is her account - a thread of recovered documents, letters and testimony that you assemble alongside the physical journey.
As a prequel to 2019's Stygian: Reign of the Old Ones, the game does not require you to have played the original, but it will land harder if you have. The setting shares the drowned-city imagery and the same library of eldritch reference material, and the 1.0 update explicitly closes off the story that Early Access left open.
Structurally it is a survival horror game first and an RPG second, and the ordering matters. The RPG systems - artifacts, weapons, progression - exist to give you agency inside a loop that would otherwise be pure attrition. The sanity system is the clearest example: it weakens you on purpose, and the game pays you back with content you could not otherwise reach.
Reception has been positive, with Steam reviews described as Very Positive across several hundred reviews. The 1.0 release also brought performance work in Unreal Engine 5, including Nanite and Lumen.
Kingsport is a city that has been submerged for long enough that the architecture has become geography. Streets end at walls that were once floors. Whole districts are vertical. The fog is not atmosphere alone - it is a mechanic that limits sightlines and turns navigation into a memory problem.
Because the map is unforgiving, the practical skill in this game is mental mapping. Learning which stairwell leads to which street is worth more than any early upgrade. Several areas also change as the story progresses, which invalidates a route you had mastered, so the map is something you keep rebuilding rather than something you finish learning.
Encounters are built around scarcity and sound. Ammunition is counted, reloads are a decision, and most enemies are easier to avoid than to defeat. The game does not reward aggression the way a standard action RPG would - it rewards knowing which fights to skip.
