Arcbound

Earth is dying, not from war or fire, but from the collapse of reality itself.

Humanity’s final hope lies in the Arcships: vast interstellar lifeboats built in orbit during the final 300 days before planetary collapse.

In Arcbound, you are entrusted with designing and preparing one of these ships for launch.

Build carefully. Stabilise your systems. Protect your crew. Decide what survival means.

Because when the launch window closes, there is no return.

Design Your Arcship

Begin with a fragile orbital platform and expand it into a self-sustaining spacecraft.

Construct living quarters, engineering bays, hydroponics systems and storage modules while balancing space, efficiency and safety. Every layout decision matters.

Build walls, floors and compartments.
Manage airflow, power and water systems.
Create functional rooms for crew survival.
Optimise your ship under constant time pressure.

Your ship becomes a reflection of your decisions.

Manage Your Crew

Your crew are survivors, not disposable units.

Each crew member develops skills, relationships and beliefs shaped by life aboard the ship.

Keep them alive and functional by managing hunger, oxygen, sleep, morale and workload. Social dynamics and psychological pressure can influence how your ship’s culture evolves over time.

A stable crew builds hope. An unstable one can threaten everything.

Risk Missions to a Dying Earth

Launch recovery missions back to Earth while civilisation collapses below.

Every expedition trades safety for survival.

Recover industrial resources.
Raid fuel reserves.
Rescue stranded survivors.
Accept consequences when things go wrong.

Missions always return with something, but survival always carries a cost.

300 Days Until Launch

Time is limited.

You may launch early if your ship is ready, or be forced to depart when the final window closes.

The condition of your Arcship at launch determines humanity’s future beyond Earth.
