Played through the demo
I actually enjoyed it once I got used to it.
I loved the depth of field and that, though I actually think if they had more of that, it would have been better. For instance, things are blured where your not foccused, so it would have been nice to have had the depth of field in the distance etc where your cursor wasn't pointing, and not just when zoomed in with the weapon.
Some nice touches anyway. Took me around 5 tries to get past the bit with the tank and those people with the rocket launchers.
I wonder what the graphics will be like when set to High, when the full game comes out?
