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.

Significant change to post combat
Combat OutcomesCombat no longer ends in one generic way. Enemy arcships now resolve into four distinct outcomes: Withdrawal, Forced Retreat, Boarding Capture, and Total Destruction.Withdrawal is now the default outcome in most fights, with retreat cooldowns, reputation impact, and possible revenge behaviour instead of constant repeat harassment.Forced retreat is now a major strategic win: crippled ships fall back multiple map nodes, lose strength/resources, and stay out of the fight for much longer.Boarding capture now has real outcomes:Capture ShipLoot and AbandonInstall Puppet LeadershipCaptured ships no longer always disappear. They can persist as allied clients or loyal puppets depending on your choice.Total destruction is now much rarer and gated behind catastrophic failure conditions, including reactor collapse, crew survival failure, and special disaster triggers.Pirate arcships now use special defeat outcomes, including long retreat cooldowns and one-shot salvage-field aftermath nodes when destroyed.Destroyed arcships now create meaningful aftermath:survivor rescue opportunitiesrefugee/pirate offshoot outcomessalvage sitespermanent arcship graveyardsArcship graveyards are now persistent map features with follow-up content like salvage, anomalies, pirate activity, memorial events, and continuum instability.Arcship destruction now causes broader sector shock:doctrine-based reaction eventswider reputation fallouttrade disruption that can propagate across the sectorThe sim now protects sector population better:minimum living arcship count is enforcednew arrivals appear with narrative justifications instead of silent replacementsDefeated AI arcships now remember losses and can react by militarising, seeking alliances, collapsing internally, fragmenting, or pursuing revenge.Destruction pacing is now capped so campaigns do not spiral into wiping out the whole sector.Arcships now use a fuller combat model including HullIntegrity, ShieldIntegrity, ReactorIntegrity, C...Read full article on Community Announcements (Vathugu)Patch NotesOfficial
