HOLLOW KEEL

HOLLOW KEEL

The ship does not need to lie. Your report needs its history to have happened once.

You are a Wreck Surveyor returning alone to a derelict vessel.

You have already inspected it. You have already signed the report. Your conclusion has already set a recovery operation in motion.

Now an independent review is approaching, and you have one unsupervised return to determine whether the wreck can still support what you claimed.

HOLLOW KEEL is a solo, print-and-play sci-fi horror investigation about route control, physical evidence, and the consequences of deciding what to preserve and what to take away.

What you do

- Survey a failing network: Discover routes, control them with three dice used as temporary survey beacons, and validate loops to establish reliable access.

- Reconstruct an event sequence: Record only chronological relationships directly supported by physical evidence.

- Choose what survives: Preserve evidence in place or extract portable material at the cost of its original context.

- Decide when to return: No oxygen countdown forces you deeper. How far to investigate is your decision.

The wreck does not provide a simple answer. Your investigation is about what can be proved, not what you want to believe.

What you need

- Three double-sided A4 gameplay sheets

- Exactly three six-sided dice (3d6)

- A pencil

- An optional notebook

Included in the download

- Illustrated 45-page A5 rulebook

- Six-page A4 gameplay sheets

- 56-page mobile-friendly rules

- One-page A4 quick reference

Important: Keep Gameplay Sheet 3 closed until your first physical arrival at L8, as instructed by the rules.

Format: English-language solo tabletop print-and-play. No software required.
