A signal got out of a place that was sealed
The year is 2078. Lunar Base Alpha went silent after the Red Horizon incident, and Ashlight Recovery breaches a sealed sector three months later. Power is unstable, life-support is failing, and something left behind is not only hunting — it is listening.
Where
Lunar Base Alpha. NovaTech's research base on the ridge between two craters at the Moon's south pole, built on top of something it found in the dark below.
When
2078, plus three months. The base went silent during an eclipse. A signal got out ninety-one days later, and that is why anyone went back.
Who you are
Ashlight Recovery. Unnamed contractors sent in to restore systems and carry out evidence. Not sent in to fight anything.
One shadow, two names
The game's title and the program's name describe the same moment, from opposite ends of the same shadow.
From Earth: a blood moon
During a lunar eclipse the Moon is lit only by sunlight bent through Earth's atmosphere, and it turns red. The eclipse of 2078 was a partial one, barely worth a photograph: only the Moon's southern edge went dark.
The southern edge was Lunar Base Alpha.
From the Moon: a red horizon
Stand on the base's ridge during the same eclipse and look up. Earth turns black, ringed by a thin band of red light: every sunrise and every sunset on the planet at once.
NovaTech's lead scientist named the program after that ring, so that nobody would forget what the thing under the base was waiting for.
It is one shadow, seen from both sides.
Red Horizon, in order
From a survey that heard something answer, to the run you play.
2071
Something under the ridge answers
NovaTech survey machines map the Moon's south pole for ice and pick up a return from under a shadowed crater floor that is not an echo. NovaTech buys the ridge and builds a base on top of it.
2074
Lunar Base Alpha and Red Horizon
The base opens its public decks. Below them, NovaTech's Red Horizon program starts feeding power, station telemetry and recorded crew voices to what it found.
2078 · Totality
The eclipse
During a partial lunar eclipse NovaTech runs its riskiest trial. Earth's shadow crosses the base, its quarantine system seals it, and Lunar Base Alpha goes silent.
+3 months
A signal gets out
A damaged message leaves the sealed base carrying a valid crew biometric stamp. Nobody can explain how it was signed.
Now
Ashlight Recovery goes in
Your squad restores failing systems, recovers NovaTech evidence, and extracts before rewritten station machines turn the base against you.
Totality, minute by minute
Recovered records are stamped from the minute Earth's shadow reached the base. The first ninety minutes, as the records tell them:
| Time | What the records say | Record |
|---|---|---|
| 03:17 | Earth's shadow reaches the ridge. The solar arrays read zero and the reactor carries the base alone, held at NovaTech's trial frequency. | OPS_078 |
| 03:21 | Service robots ignore three shutdown commands and drag sample carts toward an exterior lock. | AEGIS_003 |
| 03:24 | AEGIS votes quarantine and seals the base. Seven minutes have passed. | AEGIS_003 |
| 03:26 | The base commander holds Outer Lock Twelve against orders for nine minutes. | CREW_ROURKE_04 |
| 03:42 | A corporate override reopens the route, eighteen minutes after the seal. | AEGIS_003 |
| 03:58 | A message is recorded in Lab C. It does not leave the base. | COMMS_091 |
| 04:40 | AEGIS refuses to purge the air from a dormitory where three suit beacons are still moving. It is overruled. | AEGIS_019 |
Six names in every record
Everyone involved has a defensible public reason and a private one. The records are where the two stop matching.
Ashlight Recovery
The recovery contractors you play: up to eight operators, unarmed, breaching a facility sealed for 3 months. Ashlight calls itself independent. Read the ledgers before you believe it.
NovaTech
Owns the base, the research and the evidence, and pays for the contract that recovers it. Its briefings are accurate in the way a legal document is accurate.
Lunar Emergency Authority
The off-world rescue regulator. It opened contract 7-Alpha because a signal carried a live crew signature. Its oversight officer, Inspector Tomas Iriarte, has started leaving notes inside the base.
AEGIS
Lunar Base Alpha's security and quarantine system. It sealed the base seven minutes into the eclipse and was overridden eighteen minutes later. It still decides which doors open, and its voice is not always its own.
Red Horizon
The incident that sealed the base, and the NovaTech program behind it. Beneath both: a lattice of crystal, tissue and signal that was under the ridge long before anyone built on it.
The Chorus
What the crew called the voices on internal comms: dead colleagues asking for tools, jokes weeks out of date. AEGIS counts fifty-eight people on the base, and fifty-nine voices.
The names in the records
None of these people is you. You are an unnamed Ashlight contractor. These are the names you will find written down.
Director Mara Voss
NovaTech incident commander
Calm, precise and legally careful. Led the 2071 survey that found the site, and handles the Ashlight crews from orbit.
Status Active, in orbit
Inspector Tomas Iriarte
LEA oversight officer
Cannot reach the crews through NovaTech's channels, so he leaves letters where only they can read them.
Status Active
Dr. Anika Vale
Red Horizon lead scientist
Asked to stop the survey in 2071. Named the program. Objected to the eclipse trial in writing. Her signature is on the signal.
Status Vitals lost, E+2
Commander Elias Rourke
Base operations commander
Held Outer Lock Twelve for nine minutes. Gave one order afterwards that the base still enforces.
Status Suit beacon active
D. Reyes
Maintenance technician
Heard a dead colleague in the vents on the third day, and started writing everything on paper.
Status Suit beacon intermittent
J. Kessler
Maintenance technician
The night-shift joker who talked to the samples. Died the day after the eclipse. Still the most common voice in the vents.
Status Deceased, E+1
Dr. P. Nand
Chief medical officer
Named the symptoms cognitive contamination, and wrote down what the ward frames learned at the bedside.
Status Suit beacon active
Not aliens — the machines were rewritten
The thing that makes Lunar Base Alpha dangerous is not something that arrived. It is the station itself: its machines have been rewritten into corrupted machine-flesh frames, and they are still running on the base's own power. What rewrote them was in the lunar rock before there was a base. NovaTech plugged it in.
They react to what you do
- Sound. Proximity voice is not a chat feature here — it is a thing that travels, and something is learning it.
- Movement. Running solves a problem quickly and creates a different one.
- Light. A flashlight is the difference between seeing and being seen.
- Power. Every system you restore changes what the base can do, for you and for them.
Why that changes the run
Because the threat reads the same signals your objectives produce, restoring the base is never purely good. Lighting a sector helps you find the evidence and helps something else find you.
That tension is the whole design: there is no loadout answer to it, only decisions made together, usually in a whisper.
Seven machines, seven old jobs
Every frame in the base was a station machine first, and it still does its old job. That is the whole trick to surviving one.
Echo Mimic
Built as a relay repeater that carried crew calls through dead zones.
Learned which recorded voice makes someone stop and turn around.
Reliquary Statue
Built as nothing. It is the lattice from NovaTech's cold vault, grown to human height.
Learned that nothing grows while someone watches it under light.
Bulkhead Brute
Built as a bulkhead rig that braces pressure doors.
Learned the crew's knock, but not the pause in it.
Ward Attendant
Built as a bedside medical frame.
Learned grief, and what it means when a room fills with people and light.
Sounding Frame
Built as the 2071 survey machine that found the lattice.
Learned to listen, for longer than anyone alive.
Lockstep Sentry
Built as AEGIS's quarantine enforcer.
Learned that in a sealed sector, anything that moves is contamination.
Custodian Frame
Built as a crew-welfare steward that also served the officers' mess.
Learned a standing order: no one walks alone.
Seven questions the records keep circling
The records do not agree with each other, and they are not meant to. Nothing on this site answers these. Some records are public; the rest are still inside the base.

What a mission actually is
Blood Moon Horror is built around co-op decisions under pressure inside a quarantined lunar facility: restore unstable systems, collect NovaTech evidence, keep the squad together, and extract before Red Horizon's aftermath turns the base against you.
- Breach a sealed sectorQuarantine held for three months. You are the reason it stops holding.
- Restore what still worksPower and life-support are failing. The electrical objectives are how you push back.
- Recover the evidenceNovaTech's documents are the mission. Every record is stamped, and the stamps do not always agree with the briefing.
- Extract togetherBefore the base locks down again — and it will.
Story FAQ
Do I need to know any of this to play?
No. The mission works as a co-op survival run without a word of it. The lore explains why the base is dark, why nobody is coming to help, and why the evidence is worth carrying out — which tends to make the quiet parts land harder.
Is Blood Moon Horror about aliens?
No. Nothing arrived. What rewrote the station's machines was in the lunar rock under the base before anyone built there, and the things that hunt you are the base's own machines. NovaTech plugged it in.
Why is it called Blood Moon Horror?
Because the incident began during a lunar eclipse. From Earth, the Moon's southern edge turned red: a blood moon. From the base on that southern edge, Earth was ringed in red: a red horizon. Same shadow, two names.
Is the story finished?
Blood Moon Horror is in Steam Early Access, so the world is still being built out alongside the systems. What is on this page is settled canon, and the seven open questions are open on purpose. The roadmap covers what is being added.
Why does the squad have no weapons?
Because Ashlight is a recovery team, not a strike team — and because a gun would answer questions the game would rather you solved. Every threat in the facility is handled with light, sound, positioning and the base's own systems.
What does “machine-flesh” mean?
The station's machines were not replaced by something else. They were rewritten — still the base's own hardware, still running on its power, no longer doing what it was built for.
