Grave Orbit

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.

But survival is not just about holding the line.

Every assault leaves something you can use. Recover the wreckage, turn it into production, expand and upgrade the defenses around your Core, then put the system you built against an even greater attack. Each battle feeds the next cycle of growth.

What begins as a fragile defense gradually becomes a powerful automated network of production, support systems and weapons, but every expansion creates new demands. Firepower needs ammunition. Automation needs resources. Damage needs repairs. Building a stronger defense also means building an economy capable of keeping it alive.

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.

Take what you recover into the Workshop and decide what the next version of your defense becomes. Expand production, add new modules, strengthen existing systems and push automation further.

The challenge is not simply to make everything stronger. Your defenses are a connected system. More weapons increase the demand for ammunition. Support systems compete for resources. Production and collection must keep pace with the firepower they sustain.

Build well, and a desperate outpost becomes a self-sustaining war machine.

Build badly, and the next assault will find the weakness.

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 defenses into Skirmish mode and see how long they can survive outside the campaign.

Earth buried what happened out there.

It could not bury the consequences.
