Based on demo
I recently d/l the demo from live. At first i didnt like so turned it off but then after a few days i turned it back on for a 2nd chance. Im glad i did. The graphics i would give a 9/10 there are a few flaws but only few like tiny bit of frame rate problem but i can handle that. But the noise of the dinosouse are top notch when you here the screems of the raptor sounds kewl. Also what bothered me at first was the Sound FX of the gun when fired that could use a bit more effort to make it sound like a real gun.
What else i found good was that you could creep up on enimies and it showed you a 3rd person view of him stabbing the enimy which looked new and fresh idea.
overall all i would give the demo a 8.5 out of 10 as some could be improved. We shal see for the full version on 8/2/08
