SYS / 01
Run the machinery
Tune atmosphere controls, supply power, inspect the numbers, and notice the problem before the room notices for you.

Keep the lights on.

The station is the story
A home built one room, wire, and bad decision at a time.
Shape modular decks, route the systems that keep them habitable, and give your crew somewhere worth surviving for. Every corridor connects people, machinery, and the next problem.
Every failure becomes a story. An unforgiving space-station simulation for players who love the emergent survival of Kenshi and RimWorld and the physical, interconnected ship systems of Ostranauts.

Under the panels
Everything is a system.
Everyone is a liability.
The ship is more than scenery. Pressure, power, doors, cables, equipment, crew health and faction trouble all share the same fragile space.
CREW / 02
Look after your people
Crew bring skills, needs, injuries, opinions, and a remarkable talent for making routine work personal.
EVA / 03
Step outside
Vacuum is unforgiving. Rival crews are worse. Equip the right team and hope the plan survives contact.
