No-Spoiler Plot Premise
Safe context for players who have not finished the first run.
Directive 8020 begins as a desperate deep-space survival mission. Earth is in crisis, the colony ship Cassiopeia is tied to humanity's future, and Tau Ceti f becomes the stage for a body-horror threat that attacks trust as much as bodies.
The central story pressure is simple without spoilers: the crew cannot safely assume that every human face is human. The Growth and Mimic threat turn routine survival choices into paranoia, making scan checks, separation, and final-message decisions matter.

Spoiler Policy
The page is structured to avoid turning a plot query into unwanted ending spoilers.
This story page is intentionally layered. The first sections explain premise, setting, and entity terms without naming late-game route outcomes. Ending explanations, Humanitarian vs Scientist framing, Curator/O Death claims, and post-credit context are marked as spoiler-heavy.
If you have not finished the story, stop after the lore table and use the guide or walkthrough instead. If you are here after the credits, use this page as a bridge into the endings tracker, secret-claim tracker, and choice consequences matrix.

Curator, O Death and Secret Claims
A high-spoiler boundary section for searches around Curator scenes, O Death content, and hidden-ending claims.
Curator and O Death searches are high-risk because players often mix secret scenes, collectibles, hints, and endings into one claim. This page can explain what those ideas mean in story context, but it should not say that Curator or O Death content unlocks a secret ending without route evidence.
Treat Curator/O Death as story-adjacent and evidence-labeled. If a claim says all secrets unlock the true ending, that belongs in the Secret & Hidden Endings tracker until repeatable proof exists.
