Description
About This Game
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
Pause and time controls for relaxed strategic play
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.
