Rubicon ISS

Rubicon ISS is a 3D adult adventure for players who want science fiction isolation with a mix of horror and humor. The mood stays tense and character-driven rather than lighthearted.

Story

In the 29th century, humanity has barely managed to colonize three star systems. As a Commander with the Proxima Space Agency, you join an interstellar mission to Tau Ceti to investigate a total communications blackout, a mission that defies the protocols set by the older Sol system agencies. Roughly fifty years into the journey, mostly spent in cryo-sleep, you and your small crew now face the isolation and danger of deep space with no clear backup and no easy way home.

Gameplay

You spend your days managing shipboard duties and the wellbeing of your crewmates while the ship pushes on toward Tau Ceti. Conversations and choices shape how relationships with your shipmates develop, with adult scenes woven into the story rather than presented as a separate mode. The horror elements surface gradually, tied to the growing sense that something aboard the ship, or waiting at the destination, isn't right.

Features

• A small, isolated crew whose dynamics carry the story forward
• Sci-fi setting grounded in a believable, underfunded future rather than clean utopian tech
• Tone that shifts between dread and dark humor rather than staying purely grim
