3D Realms has announced Play Demo for a June 22 release on Xbox Live and PC.

Altogether, a generous selection of five levels from the game will be featured in the demo, which is extracted from single-player and multiplayer game modes. 3D Realms is yet to determine the size of the demo, the kind of levels that it will include in it and the timing of the day to release it.
You will be able to try out not only the PC version of Prey but also Xbox 360 one. The lucky ones who are presented at the E3 event had the chance to play the game there and the frustrated souls only had to content themselves with Prey E3 trailer, which is not half as exciting as the last year's one.
