Blood Moon Horror is a 1–8 player co-op survival horror game set inside a quarantined lunar research facility after the Red Horizon incident.
The blood moon has risen. The base has gone silent. Something inside is awake.
You have no weapons. No backup. No easy way out. Work together, stay quiet, restore failing systems, and escape before corrupted machines in the dark learn how to hunt you — by sound, light, and power.
The Blood Moon Horror Demo is a focused preview of the main game’s co-op survival horror experience.
This demo lets you enter Lunar Base Alpha alone or with friends, explore a limited section of the facility, complete core objectives, solve electrical puzzles, collect evidence, avoid hostile station threats, and attempt to escape before the base overwhelms you.
The demo uses a limited mission setup and a single gameplay seed, giving players a controlled sample of the atmosphere, tension, objectives, and enemy behavior found in the full Early Access version.
Explore – Search a limited section of Lunar Base Alpha for clues, access points, and mission-critical systems.
Restore – Repair electrical systems, solve switch box puzzles, and bring parts of the base back online.
Investigate – Collect files, recordings, and evidence connected to Red Horizon and the disaster that followed.
Survive – Avoid hostile station threats, manage noise, stay together when you can, and split up only when you must.
Escape – Complete your objectives and reach extraction before the base — or what’s inside it — overwhelms you.
1–8 Player Co-op Horror – Enter Lunar Base Alpha alone or with a team and experience the core co-op survival loop.
No Combat. Only Survival. – There are no guns and no traditional fighting mechanics. Hide, run, distract, and survive.
Proximity Voice Chat – Speak to nearby teammates through in-game voice chat. Whisper plans, call for help, or listen carefully.
Enemies That Hunt by Sound, Light, and Power – Threats react to movement, noise, light, and electrical activity. Slam a door, trigger a puzzle, or speak too loudly, and you may give away your position.
Biomechanical Station Threats – Corrupted security frames and service robots patrol the facility, investigate disturbances, and punish careless behavior.
Electrical Puzzle Gameplay – Restore systems through switch boxes and objective-based interactions. Mistakes create noise, sparks, and new danger.
Environmental Storytelling – Collect documents, logs, and clues to uncover what NovaTech discovered beneath the lunar surface.
Claustrophobic Lunar Atmosphere – Explore dark corridors, failing systems, emergency lighting, and a soundscape designed to make every step feel dangerous.
The demo is designed around communication, tension, and bad decisions made under pressure.
One player may be restoring power while another searches for documents. Someone may be hiding in a dark room, whispering for help. Someone else may hear that whisper coming from the vents.
Every mission is about teamwork — but fear makes teamwork difficult.

The year is 2078. Lunar Base Alpha was built to push humanity further than ever before — until its final transmission ended in panic:
"The moon... it's changing. The samples... they're alive. We can't contain—"
[TRANSMISSION ENDED]
Three months later, your Ashlight Recovery team breaches a sealed sector to investigate. The corridors are empty. The power is unstable. Life support is failing.
And what was left behind is not only hunting — it is listening.
Search the facility, recover crew logs and evidence, complete dangerous objectives, and reach extraction before quarantine locks you in again.
Blood Moon Horror contains intense horror themes, jump scares, confined spaces, darkness, disorienting audio, isolation, and scenes designed to unsettle players. Online voice chat may also include sudden or startling sounds from other players.

Work together. Stay quiet. Restore power. Escape before the base learns where you are.
The base is silent. The blood moon is rising. How long can your team survive?
