Bethesda has confirmed that PS4 and Xbox One owners will be able to sample Prey as a demo of the game’s opening will be released on April 27th. The demo is titled Opening Hour and, as the name suggests, will allow people to experience the first hour of Prey. You’ll see the early events unfold where the space station Talos 1 gets overrun with the crew members being killed by the aliens.
Prey will be releasing on May 5th for PS4, Xbox One, and PC. As you may have noticed PC players will not get a demo before launch.
