Stygian: Outer Gods is a survival horror game with RPG elements, developed by Misterial Games and published by Fulqrum Publishing. It launched in Steam Early Access on April 14, 2025, for PC. The game draws on the cosmic horror themes of the Stygian universe and asks you to unravel a thousand-year-old mystery tied to the Outer Gods.
Survival drives the gameplay. Ammunition is scarce, every encounter has a cost, and your character's sanity can slip as you face the unknown. RPG systems let you shape your skills, and the choices you make change how events play out. It is a single-player experience with full voice acting in English and text support for several other languages.
A Stygian: Outer Gods CD key suits players who prefer slow, tense horror over action and who enjoy resource management and Lovecraftian themes. Because it is in Early Access, content and balance may still change. Follow development on the official Steam store page.
