Grey Goo

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, frankly, fantastic. From the opening scenes through the entire narrative thread of the campaign, you’ll want to improve your game if only so you can see what happens next as quickly as possible.”

– The Escapist
