They buried the truth. The invasion did not end. Now it is coming home. Grave Orbit is a dark sci-fi survival campaign of relentless escalation, impossible odds, and a war that grows far beyond anything humanity was prepared to face.
They buried the truth. The invasion did not end. Now it is coming home.
What began as an isolated incident at the edge of the Solar System was erased, contained, and forgotten.
It should have ended there.
Instead, the enemy kept coming.
In Grave Orbit, every battle pushes you deeper into a dark sci-fi campaign where survival is never permanent, victory is never clean, and each new chapter reveals a threat larger than the one before it.
Build your position. Strengthen your arsenal. Automate what you can. Then hold against assaults designed to overwhelm everything you have created.
But Grave Orbit is not a war fought in one place.
The battlefield moves from the distant reaches of the Solar System toward the Moon, Earth’s orbit, and finally the surface below. Across 4 acts and 16 chapters, new enemies appear, familiar rules break, weapons evolve, and defenses that once felt unstoppable become barely enough.
And behind it all, something vast is drawing closer.
SURVIVE THE ESCALATION
Each chapter changes the pressure.
Enemy forces grow stronger, faster, stranger, and more numerous. New threats demand new answers, while bosses turn every hard-earned advantage into a desperate test of survival.
BUILD POWER BETWEEN BATTLES
Every run leaves something behind.
Expand your Workshop, unlock new technologies, strengthen your defenses, and return better prepared for what comes next. Progress is persistent, but the enemy never stops evolving.
FIGHT YOUR WAY HOME
The farther you travel, the greater the war becomes.
What starts as survival in forgotten space grows into a battle for humanity itself. Follow the invasion across the Solar System, uncover what was hidden, and face the force waiting at the center of it all.
BEYOND THE MAIN CAMPAIGN
Discover how the first incident began in a dedicated Prequel, then take your strongest builds into Skirmish mode and see how long they can survive outside the campaign.
The first attack was buried.
The next one will reach Earth.
