Aspyr has released a free demo of its forthcoming first person shooting title Prey for Mac.

The 454MB demo is available for free download from MacGameFiles.

Prey is a first-person shooter that turns the genre upside down with new gameplay features and next-generation graphics. It introduces new gaming elements, including wall walking, portals, spirit walking and gravity flipping.

It's the story of Tommy, a Cherokee garage mechanic stuck on a reservation. His life changes when an otherworldly crisis forces him to awaken spiritual powers from his long-forgotten Native American birthright. Abducted along with his people to a spaceship orbiting Earth, he sets out to save himself, his girlfriend and his planet.
