Publisher's description of Prey demo
This game is intended for adult audiences only. It contains graphic violence and profane language.Prey tells the story of Tommy, a Cherokee garage mechanic stuck on a reservation going nowhere. Abducted along with his people to a menacing mothership orbiting Earth, he sets out to save himself and his girlfriend and eventually his planet.
In Prey, players enter a living spaceship that enslaves alien races and devours humans for lunch. Prey turns the first-person-shooter genre upside-down with new gameplay features like wall-walking and gravity flipping, making for intense single- and multiplayer experiences. Prey is built on a heavily modified version of Doom 3 engine and is developed by Human Head Studios under the direction of 3D Realms.
