[i]Prey[/i], the much anticipated first person shooter from 2K Games and 3D Realms is now available on Xbox Live. The demo comes in at 1.17GB and lets gamers play single and multiplayer levels. It seems as though all the gravity defying, portal jumping action is intact from the PC version. [i]Prey[/i] was built on an enhanced [i]Doom 3[/i] engine, the most impressive 3D engine used in a released game. The portal technology adds a new dimension to gameplay, allowing enemies to appear out of thin air and create new and completely original puzzles and gameplay styles.

[i]Prey[/i] 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. [i]Prey[/i] makes use of Joseph's Campbell's renowned story structure, "The Hero's Journey," for guiding the main character arc. Campbell's extensive work on mythological story progression was made famous when George Lucas used it for Luke Skywalker's story arc in the original [i]Star Wars[/I].

[i]Prey[/i] is scheduled to be released on July 11. It will be rated M for mature, and will retail for $59.99 for the Xbox 360 and $49.99 for the PC.
