OK I played one hour, it does indeed seem very polished for an UE3 game... Digital Extremes and Epic are butt buddies and it shows
the whole game is nothing but tints of gray with a few colors here and there and lots of shadows, it's a pretty original look and it's very impressive at times, it helps a lot to mask the roughness of the assets
the action itself seems OK, but it has an unoriginal cover system like Killswitch, Gears and Uncharted have, though... this kind of gameplay is beginning to feel fuck boring
I didn't like the enemy AI, they seem to have weird animations too, they move strangely when they're shooting you and then move
also the aiming is pretty shitty, I tried to change the sensitivity of the analog sticks but it wasn't improved
