Prey now available on Steam

3D Realms' sci-fi FPS Prey is now available for digital download on Valve's Steam service.

If you've yet to pick up Prey, then now is your chance to do so in non-boxed form via Steam. The impressive, but short-lived, FPS will cost you $49.95 and you don't even need to leave your chair.

The Steam website also states that anyone who has already bought a boxed or other digital download version can activate a Steam copy at no cost by entering in their existing product key.
