Prey demo for 360 and PC on June 22

3D Realms has announced the June 22 release of a Prey demo on Xbox Live Marketplace and PC.

The demo will feature five levels from the game, taken from single-player and multiplayer game modes. 3D Realms says that the size of the demo, what levels will be included, and what time of day the demo will be released, are all still to be determined.

Prey features the original storyline that sees Tommy, a Native American mechanic, somehow at the centre of an alien invasion, and must use the powers of his ancestors (plus some guns) to defeat the alien threat. Prey is scheduled for release in Europe for Xbox 360 and PC on July 14.
