Rubicon ISS [Ep.1 v0.1.7] [TNC Studio]

December 25, 2025F95

What if Earth’s space agencies never had a budget that allowed them to explore space in a relatively timely manner? It’s the 29th Century and humanity have colonized three star systems. Barely.
You, a Commander from the Proxima Space Agency, have joined an interstellar mission to Tau Ceti to investigate a system-wide communications blackout. At 0.3c, you are now around fifty years into the journey, most of it in cryo-sleep.
The Sol system agencies, Trans-Jovian Expansion Agency and Orion Space Agency – Mars Integration, have laid the foundation and laws that your agency abide by. Sending you to Tau Ceti broke those protocols.
Now, with your small crew, you will face true isolation and the brutal reality that is space, take care of your fellow shipmates and do your job.
For Proxima.
