Arcbound is a relaxed sci-fi colony simulation about building humanity’s last refuge among the stars.

Design and expand your own Arcship, manage a small crew of survivors, and guide a fragile civilisation through the final days before Earth’s collapse, and beyond. Every corridor you build, every mission you launch, and every decision you make shapes not only your ship, but the culture that emerges aboard it.

Balance oxygen, food, power, morale, and social stability while your crew works, rests, argues, and adapts to life in deep space. Stabilise your ship before launch… or risk carrying your problems with you into the void.

Arcbound focuses on thoughtful planning, emergent stories, and calm strategic gameplay, with moments of crisis when systems fail or people disagree on how survival should look.

BUILD YOUR ARCSHIP

Start with a small emergency platform and grow it into a functioning star-faring vessel.

Design living quarters, engineering bays, hydroponics, research facilities, and life-support systems while managing power, water, atmosphere, and maintenance across a fully simulated ship.

A well-designed ship creates stability.
A poorly planned one barely survives.

MANAGE YOUR CREW

Your crew are more than workers.

They form friendships and rivalries, develop beliefs, suffer stress, and react to the decisions you make as commander. Social relationships and ideology evolve over time, influencing morale, productivity, and the long-term identity of your Arcship.

Rescue new survivors, but every arrival may change the culture of your ship.

SURVIVE THROUGH MISSIONS

Send crews beyond your vessel on dangerous expeditions to secure vital resources.

Recover technology, extract survivors, or raid for fuel, missions always return something, but consequences follow. Injuries, conflict, and unexpected events can reshape life aboard your ship long after the mission ends.

FROM ESCAPE SHIP TO STAR-BOUND SOCIETY

Early Access includes both phases of Arcbound’s journey:

Phase 1: The Exodus
Stabilise your ship before Earth collapses and prepare for launch.

Phase 2: The Voyage
Guide a growing civilian population during multi-year transit as your Arcship becomes a living society facing internal pressure, scarcity, and unknown signals from deep space.

A CALM SURVIVAL EXPERIENCE

Arcbound is designed as a chilled but thoughtful space management experience. Most of the time you’ll be carefully expanding and optimising your ship, until emergencies, social tension, or difficult choices introduce moments of drama.

There is no single correct way to survive.

Only the ship you build… and the future it creates.
