Arcbound is a colony simulation game set entirely on a single evolving starship.

Everything is connected. And everything can fail at any moment.

Design and expand your ship room by room, manage oxygen, power, and crew survival, and guide a fragile civilisation from Earth’s final evacuation into deep space.

WHAT YOU DO

Design and expand your Arcship room by room

Manage oxygen, power, water, and food to keep your crew alive

Send missions to Earth to recover resources and survivors

Grow your ship into a self-sustaining spacefaring civilisation

Every system connects. Every decision has consequences.

Inspired by classic colony sims, Arcbound takes the genre into a single fully interconnected starship, where layout, systems, and social dynamics are tightly linked.

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.

BUILD YOUR ARCSHIP

Start with a small emergency platform and grow it into a fully 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.

Missions can trigger injuries, political tension, or unexpected consequences that ripple through life aboard the ship.

KEY FEATURES

Grid-based ship construction and expansion

Fully simulated oxygen, power, water, and resource networks

Crew needs, skills, relationships, and ideology systems

Consequence-driven mission system

Research unlocking new technologies and discoveries

Civilian population and societal stability management

Emergent storytelling driven by player decisions

Designed for long-form sandbox progression

In Arcbound, your entire civilisation exists within a single evolving Arcship. Every decision shapes not just your ship, but the society living inside it.

Stabilise your ship before Earth collapses… or carry your failures with you into the void.

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 you create.
