Centuries after Humanity first left Earth, all forms of life in the Milky Way have evolved toward an inward tranquility. But there has been a mutation. A mysterious organism barrels toward the surface of a lone, resource-rich planet known as Ecosystem 9, on a mission to consume all it encounters.
Grey Goo is a real-time strategy (RTS) game that combines classic strategy mechanics and a balanced combat system with an emphasis on large-scale decision-making. It puts you at the center of a tactical struggle for survival—and ultimately, control of Ecosystem 9.
