Grave Orbit

Grave Orbit is a sci-fi tower defense and resource management game where players defend a central core, collect scrap, produce parts and ammunition, and build automated defenses against escalating enemy waves.

A remote Core is deployed on what begins as a routine operation at the edge of the Solar System. At first there is only dust, stone and silence. Then something moves. Strange scouts appear, the void turns blood-red, and the Core finds itself in the path of an invasion that is spreading toward Earth. Forced to retreat from one battlefield to the next, it fights through the Moon, Earth orbit and the surface while humanity struggles to understand what is attacking and why. What begins as an isolated encounter becomes a war for survival, and with every step closer to Earth, the true scale of the threat is revealed.
