A guy on this forum noticed another guy in his friends list playing the F.E.A.R demo. This dude replied in the thread later on saying that due to his work he got hold of a demo disc. He also told that this disc will be enclosed with the next issue of OXM next month.

There’s not much information available whether this demo will make it to the Xbox Live Marketplace anytime soon so you’ll just have to go outside (yikes) to get a copy of OXM. But fortunately most demos make their way to Live a month later like Saints Row or Full Auto. The guy in question did say that he’d update the thread with details at a later time.

If you can’t wait for this disc or the marketplace, you can try the PC demo if your computer is up to it. You’ll need a pretty fast computer to match the Xbox 360 detail levels if that’s even possible at all. Some rumours say that the Xbox 360 version has updated graphics.

F.E.A.R (First Encounter Assault Recon) is a unique fusion of sylized first person combat and supernatural suspense in which you are an elite soldier trained to deal with situations others can’t even imagine. Be the hero in your own spine-tingling epic of action, tension and terror and discover the true meaning of fear.

A mysterious paramilitary force infiltrates a multi-billion dollar aerospace compund, taking hostages but issuing no demands. A special Forces team is sent in by the government to contain the situation, but the contact is severed as an eerie signal interrups radio communications. When the interference subsides moments later, the team has been obliterated. Live footage of the massacre shows an inexplicable wave of destruction tearing the soldiers apart before they can even react.

Thanks to LinkinPrime for the pointer.
