Just been playing it for about 30 minutes… looks amazing, plays amazing, nice touch with a lens look on the screen when you using your night vision googles. Great stuff, and the demo provides videos and hows to’s on new tricks , new moves, basically a break down of the games controls…
only downer is the demo is just under 600meg. :!:
but worth it…
