It's been a painful wait, but a demo of Prey is now available to download on Xbox Live Marketplace.

The demo was originally scheduled to hit marketplace on June 22, accompanying the PC demo, but Xbox 360 owners were left cursing their luck when it failed to materialise. The short wait is now over, as the demo has finally made its way to Xbox Live Marketplace. Sadly, if you live in Japan or Germany, there's no demo for you.

Developed by Human Head Studios in conjunction with 3D Realms, Prey makes use of the Doom 3 Engine to create an atmospheric alien environment. The PC and Xbox 360 versions of the game will arrive in North America on July 11, and a few days later in Europe on July 14.
