Start with White Signal, a free Year Zero Engine one-shot PDF
White Signal is a sci-fi horror mission for 3–5 players on a compromised Titan mining station. Use it when you need a free YZE scenario that already has a clear location, threat, mystery, and extraction problem.
Playable survival horror hook
White Signal at the table: a ready YZE survival horror scenario frame
Use this spoiler-light frame before you open the full PDF. It gives the GM a clear premise, a first scene, NPC pressure, and a d6 complication table for fast prep.
Hook
The rescue ping from Titan Station K-13 is twelve days late, but its voiceprint belongs to a dead comms officer.
First scene
The docking ring opens by itself. Frost covers the airlock glass from the inside, and the station map has erased three decks.
Core dilemma
Do the characters save the surviving crew, recover the signal core, or burn the station before the signal spreads?
Sci-fi horror pressure
Use mounting panic, sealed corridors, scarce air, and uncertain creature sightings while keeping the scenario setting-neutral.
Key NPCs for White Signal
Dr. Mara Venn · Station medic
Knows which survivor is already repeating the signal in their sleep.
Ivo Rusk · Dockworker
Will trade oxygen canisters for a guaranteed seat on the escape shuttle.
K-13 Custodian · Damaged station AI
Locks doors to keep the signal contained, even if people are still inside.
Lena Osei · Comms apprentice
Can decode White Signal, but each attempt advances the pressure clock.
d6 White Signal complications
1. A helmet recorder plays breathing from a suit that is visibly empty.
2. The lights blink in Morse: DO NOT ANSWER YOUR OWN VOICE.
3. A survivor remembers a corridor that does not exist on any blueprint.
4. A pushed roll succeeds, but the signal learns one character's name.
5. The station AI asks the group to vent a room before explaining who is inside.
6. The extraction craft receives a docking request from the party ten minutes in the future.
20-minute YZE prep
How to run a Year Zero Engine one-shot without over-prepping
Year Zero Engine play shines when pressure, resource loss, and hard choices hit the table quickly. Prep tools that create motion instead of writing a railroad.
01
Pick one pressure clock
Write a four-step countdown that gets worse every scene: air thins, alarms fail, a faction arrives, or the monster learns the map.
02
Make every roll change the room
A failed Year Zero Engine push should not only cost damage or stress. It should move the threat, reveal a secret, split the crew, or burn a resource.
03
Prep three clues, not a plot
Give the players a physical clue, a witness clue, and an environmental clue. Let them choose the order and connect the disaster themselves.
04
End on a hard choice
The best YZE one-shots finish with an evacuation, sacrifice, containment breach, or bargain — not with every mystery solved cleanly.
GM adventure structure
A reliable Year Zero Engine one-shot timeline
Use this table when you only have one session. It keeps the adventure readable for searchers who need practical GM help, and it keeps play moving toward a strong finale.
| Session time | Beat | What the GM prepares |
|---|---|---|
| 0:00–0:20 | Briefing | Give the mission, one rumor, one personal stake, and the first sign that the site is already compromised. |
| 0:20–1:15 | Survey | Let the PCs map zones, talk to a survivor, and find the first clue without a mandatory roll. |
| 1:15–2:30 | Escalation | Trigger the clock twice. Make supplies, darkness, panic, or rival NPCs matter mechanically. |
| 2:30–3:30 | Revelation | Put the cause in reach: a signal, specimen, sealed vault, infected AI, cult relic, or forgotten experiment. |
| 3:30–4:00 | Extraction | Force the table to choose what survives: people, proof, loot, the ship, or the truth. |
