One civilization, three voyages. From a planet torn between multiple suns, to a star cluster ruled by suspicion, to a galaxy where thousands of stars wage war — your task is to keep your people alive as the rules of the universe are rewritten around them.
A strategy game about a civilization's survival, growth and exploration. Each part is a complete voyage, and your people climb from ancient times to a cosmic civilization across three skies that follow completely different laws.
Part I · Sky of Chaos
Your civilization is born on a planet with more than one sun overhead. The planet keeps shifting between "captured by a star" and "drifting free," its temperature swinging wildly, while red giants and white dwarfs push the environment to extremes. Guide your people from the ancient era to the cosmic era and earn the right to leave this sky behind.
Part II · Abyss of Suspicion
You arrive in a cluster of dozens to a hundred stars. There are no reliable allies here, only the law of the dark forest: a trail, a broadcast, a lost fleet can reveal your position — or be someone else's bait. Build an expansion-and-strike chain with five fleet types (colony, explorer, monitor, combat, beacon), manage energy and load, seize planets, terraform worlds and research technology, and trade information advantage for survival. Hide, or strike first — the hardest choice in the game.
Part III · Galaxy of Slaughter
In a galaxy of ten thousand stars, many civilizations are born at once, expanding and going to war. Civilizations rotate between war, technological explosion and exploration-driven expansion; nova bombs and quantum cannons can erase a star, while projects and alliances decide who lasts. The star map keeps reshuffling between free, occupied and destroyed systems until only one winner remains.
Anomalies rewrite the underlying rules of a run — star counts, AI evolution speed, the tempo of information and war — so every opening presents a new challenge.
Story Mode links the three parts into one continuous voyage. As the universe level deepens, pressure rises in different ways: faster AI and wilder multi-star gravity in Part I, larger clusters in Part II, and more intense warfare in Part III. Clear 10 levels to enter the Endless Universe, where celestial laws grow stranger and civilization fates grow more dramatic.
Before each run you can configure Talents:
Play online with others: create or join a room, up to 10 players in a single match, and freely choose any of the three parts to play. The host can also set a separate anomaly for each part, and can convert a chat room into a game room on the spot.
Two-player co-op: both players begin as allies, and a teammate's victory counts as yours — even if your own civilization has already fallen. In Part II intelligence is shared unconditionally; in Part III both players are pinned into the same alliance against the AI.
Every match ends with a full results breakdown so you can review exactly how it went. The game also tracks win-count rankings, Steam achievements and more than thirty unlockable titles. In Story Mode, the ending generates a Chronicle of the Cosmos recording your three-part data, the anomalies you encountered and your civilization's final fate.
Turn on Auto Play in the settings and your civilization is handed to AI control: Part II readies each round automatically, Part III assigns skill points and builds projects on its own, and you can simply watch your people survive. Story Mode also supports Auto Next Stage, rolling straight into the next part when one ends — ideal for letting the whole story run hands-free.
After winning at least once, you can enable Admin Mode in the settings — a free-form sandbox that never counts toward your record: adjust solar collision volume and planet-devouring distance in real time, refill civilization points instantly, trigger nuclear war, war, plague and broadcast events on demand, and switch on God's View, Blink and Super Game Speed.
Admin Mode records no game data at all: wins, statistics and achievements are unaffected, so it is safe for experimenting with extreme situations.
