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.

Command one of three unique factions: the Humans, masters of defensive architecture; the Beta, a proud, versatile alien race; or the Goo, an enigmatic, highly mobile life form. Fight from behind massive walls, attack from strategic outposts, or swallow your enemies whole. Just remember, the choices you make on the battlefield will mean the difference between glorious victory and agonizing defeat.
