This is the best price I've seen yet for the PC version of this popular game - prey. It is £14.99 including delivery and there would be 2% quidco.com cashback as well.
I bought this game recently, and I'm having great fun playing it. It's running quite nicely on my ATI radeon X1900XT 512mb card...:p
Details: Prey tells the story of Tommy, a Cherokee garage mechanic stuck on a reservation going nowhere. His life changes when an otherworldly crisis forces him to awaken spiritual powers from his long-forgotten birthright. Abducted along with his people to a menacing mothership orbiting Earth, he sets out to save himself and his girlfriend and eventually his planet.
