FIGHT THE CHAOS. OR HARNESS ITS POWER.

Drawn to a remote world, intelligent lifeforms fight for control of its resources. Here they must each answer the primal choice of life...extinction or evolution?

Grey Goo is a real-time strategy (RTS) game that combines classic strategy mechanics and a balanced combat system with an emphasis on base-building. It puts you at the center of a tactical struggle for survival—and ultimately, control of Ecosystem 9.

Take on the single-player campaign to command three factions: the Humans, masters of defensive architecture; the Beta, a proud, versatile alien race; and the Goo, an enigmatic, highly mobile life form. Or compete with any of the four multiplayer factions—including the disruptive, unpredictable Shroud.
