Blood Moon Horror is a 1-8 player co-op survival horror game. No weapons—survive through stealth, strategy, and cooperation. Use proximity voice chat to coordinate, evade predators that hunt by sound and movement, solve puzzles to restore power, and escape before life support fails.
Blood Moon Horror is a heart-stopping 1–8 player co-op survival horror set in a quarantined lunar research facility—where the blood moon awakens something that hunts in the dark. No weapons. No combat. Only stealth, teamwork, and terror.
You are a rescue team sent to Lunar Base Alpha after three months of silence. The base has become a tomb: intelligent, adaptive extraterrestrial entities stalk the corridors, manipulate ventilation and power, and some even mimic human voices. Work with friends (or strangers) and use nothing but your wits to survive—because every sound could be your last.

The year is 2078. What began as humanity’s most ambitious lunar research program has spiraled into an experiment gone horribly wrong. The last transmission from Lunar Base Alpha cut off mid-sentence: "The moon... it's changing. The samples... they're alive. We can't contain—"* [TRANSMISSION ENDED]
Now you’re inside. The life systems are failing. The entities hunt by sound and electricity, slip through vents, and learn from you. Your mission: survive, uncover the truth, restore power, and escape before the blood moon finishes its work.


Customize your survivor from multiple scientist variants and unlock skins as you progress. From lab coats to rare designer variants, stand out in the darkness—or try not to be noticed at all.

Blood Moon Horror is in active development — we ship regular updates, fixes, and content additions. Current status and upcoming features below.

Blood Moon Horror contains intense psychological horror: confined spaces, jump scares, disorienting audio, themes of isolation, and scenes designed to unsettle. Proximity voice chat may carry startling sounds. Not recommended for players who are sensitive to horror conventions.

We’re building this nightmare alongside our community. Expect regular updates, open communication, playtests, and developer posts. Follow us on Steam for patch notes, feature previews, and early access to new content. Add Blood Moon Horror to your wishlist to be notified of major updates and early access drops.
The base waits. The blood moon rises. How long can you survive?
