You read the headline, there's a demo of F.E.A.R. available on Marketplace right now. Our more astute readers will no doubt notice that this demo is exactly the same as the demo available some time ago in OXM. Giving it another go this morning, X360F wonders whether or not F.E.A.R. can stand out among upcoming blockbusters like Gears of War and Rainbow Six: Vegas. Also, it may just be us, but why does this game require such a monster PC to run? There are plenty of particle effects and the textures are all very high res, but the geometry just doesn't look that impressive -- again, see Gears of War and Rainbow Six.
Still, if you haven't picked up the demo through OXM, you just can't beat the price (hint: it's free).
