Imperium of the Stars is a real-time 4X grand strategy set in a procedurally generated Gothic Space Opera galaxy. Lead asymmetric factions, expand across thousands of star systems, and survive a living galaxy shaped by a dynamic Game Director.
The Game Director ensures the galaxy never stands still. Rival empires rise and fall, galactic crises erupt, and new threats emerge as the balance of power shifts throughout every campaign.
Every faction believes it is right.
The Imperium seeks to reunite a shattered galaxy and calls it salvation.
The Void Eternal seeks to return creation to an older truth and calls it restoration.
The Grokhar take what they can hold and call it enough.
In the end, history remembers only the victors.
Key Features
Every faction plays differently - The Imperium governs through a court of great offices, ruling faith as infrastructure. The Void Eternal seeks unity through the Void’s many faces, spreading Oblivion across the galaxy. The Grokhar forge power through salvage, war, and ritual to prove the strength of their Pack-Lord.
More factions and systems are in development.Factions are starting points, not destinies - The Imperium can become a beacon or a hammer. The Void Eternal can be patient or consuming. The Grokhar can be honour-bound or ruthless. Your choices and policies define what your empire becomes over time.
Permanent faction war. - There is no diplomacy between the great powers. The Imperium, Void Eternal, and Grokhar exist in a state of perpetual war.
Only remnant systems, lost worlds drifting after the Long Silence, can be reclaimed, fought over, or consumed.Massive procedurally generated galaxies - Play across 1k to 10k star systems in configurable galaxy scales, each run generating a new strategic landscape.
Layered economy - Faction-specific resources, per-planet building queues, infrastructure tiers, sector-level governors, edicts, and income deltas broken down to the planet.
Sector-level command - Build and govern at the sector level, and group fleets into task forces that operate across entire sectors. Set priorities, define objectives, and let the task force handle the details. Full control when you want it, high-level automation when you don't.
Naval and ground combat - Fleet battles between dozens of ship classes, ground sieges with regiment-level warfare, terrain modifiers, and morale systems.
Unique asymmetric tech systems - Each faction advances through a completely different research structure, unlike anything in traditional 4X games.
The Ordinator (Game Director system) - Choose your Game Director: Balanced, Grimdark, Chaotic, and more. The unseen force shaping the epoch answers to you. Change it mid-game whenever the galaxy needs a different hand.
The Factions
The Imperium of the Stars
Twenty thousand worlds. Ten thousand years. One Eternal.
The Eternal is ancient and doesn't die, but not a god, not a tyrant. They speak rarely, and only when the word is final. The Synod turns that word into law. The court of great offices handles the rest.
The Choir is what holds the Imperium together across the dark. Shared conviction has real, physical weight on the warp. It looks like a religion, runs like infrastructure, and reaches far enough that no world it can hear gets left alone.
The Imperium's faith isn't faith in a god. It's faith in the covenant: duty and endurance, not divinity. The Synod guards that line deliberately. They mean it. The Imperium believes it's the galaxy's best shot at keeping the lights on, and ten thousand years of history give them something to stand on.
The Void Eternal
There's no clean name for what the Void Eternal actually is. Something ancient, wearing an approximately human shape. They spread Oblivion across the galaxy and call it healing.
They look at the Imperium, the wars, the faith, ten thousand civilisations grinding against each other, and see a wound. Oblivion isn't destruction. It's a return. A world touched by Oblivion stops fighting. Stops suffering. Goes back to what the galaxy was before civilisation scarred it.
The Long Dark was three hundred years of quiet. The Void wants that to be permanent.
There are no gods. There is one Void, and it isn't empty. It's full of everyone who crossed before. Every person who looked at their own pain and chose the end. In crossing, they joined it. They didn't die. They arrived. No living mind can hold something that vast in a single thought, so the Void gets met in four faces: the Hollow Moon, entropy and dissolution; the Carrion Choir, the peace that comes when the killing finally stops; the Unwritten, forgetting and the warp's slow rot; the Glutton Below, the mercy of being swallowed whole. Four ways of seeing one release. None of them hungers. They wait on the far side of every event horizon.
Ahnor-Vex, the Sleepless, leads them. A human who walked to the edge of Oblivion and was held one step back, kept from crossing so the rest could be shown the way. A dark mirror of the Eternal Emperor: both ancient, both holding a civilisation together, both convinced they're the galaxy's last mercy.
The Grokhar
Multiple packs, each with its own lord, its own iron, its own way of making war. The Grokhar build from salvage, stripped from wreckage and hammered into weapons that work because they have to. Every pack has a Pack-Lord, and the Lord must be proven. Through war, through ritual, through blood. A Lord who grows weak loses everything. A Lord who stays strong takes more.
The Grokhar don't explain themselves.
The Lattice
The Lattice are not a hive mind. They are not biological. Crystalline. A void-energy entity with no history in this galaxy before the Long Silence. They don't communicate. They don't negotiate. When their assessment of a region is complete, they advance.
"Crystal does not hunger. Crystal simply grows."
The Lattice turns up in every campaign. Every faction will run into it. It is not playable at release.
The Galaxy
Before the first fleet moves, you shape the galaxy. Choose your scale, from 1k to 10k star systems, then set your scenario and choose your Game Director. The Ordinator, the unseen force shaping the epoch, answers to you. You decide the pace and pressure, and you can change it mid-game. Dial it up, pull it back, and the galaxy responds.
Rival empires expand, remnant systems rise and fall, crises come in without asking. There is always a situation demanding attention, always a fire somewhere on the map. And when the last system finally falls, the game does not end. New threats emerge. You decide how long you play, and how hard you want it to be.
Situations and Events
The galaxy doesn't wait. Story events surface without warning: a Cardinal's petition, a Void whisper taking hold on a frontier world, a faction situation demanding a call right now. Some resolve in a single decision. Others escalate over months into something much harder to contain. A galaxy-wide crisis can shift the balance of power overnight. And faction situations cut deeper: gods grow restless when neglected, courts fracture when unattended, Pack-Lords grow bold when they go too long without blood.
Other 4X games give every faction the same tools with different numbers. This one doesn't. The Imperium's court, the Void's gods, the Grokhar's Pack-Lord are not flavour. They are the game. The Ordinator is yours to configure. Some players want constant tension and rivals that never stop pushing. Others want to build at their own pace and pick their fights. Choose your Game Director before you start, change it whenever you need to. The galaxy responds to what you ask of it.
Economy and Buildings
The economy runs at every level. Planets generate resources, house populations in the billions, and run their own building queues. Buildings unlock at infrastructure thresholds, scale through upgrade tiers, and feed into sector-level accounting. Appointed Governors manage each sector, pooling and redistributing resources across their worlds. Sector and empire edicts stack further modifiers on top of all of it.
Faith and loyalty are resources too. A world with falling loyalty bleeds output and invites unrest. Faith sustains the Choir, enables edicts, and holds the Imperium's grip on distant systems. The spiritual health of your empire is as important as its ledgers.
Combat
Naval battles pit fleets of cruisers, battleships, destroyers, and capital ships against each other. Ships carry autocannons, lance arrays, torpedo salvos, and launch bays. Ground warfare runs through regimental armies of infantry, artillery, armour, and recon battalions, with planet type shaping the fight. Fortress Worlds give defenders heavy armour. Sprawl Worlds turn every district into a kill zone.
At the centre of the galaxy, the largest black hole turns. The Void Eternal calls it a door. The Imperium calls it a heresy. Every fleet in the galaxy orbits the same point.
Ten thousand worlds. One throne. The largest door is at the centre of everything.
