Wow, finally got to play it. The most impressive looking shooter I've played this side of Crysis (and, in some ways, it's more impressive than that masterpiece). I just can't get over how much polish was put into every ounce of the game. It's just insane.
By sticking with smaller, less organic environments, you're never met with rough edges and instead are treated to perfection from start to finish.
I like the addition of cover in an FPS. It adds a dimension to the game that was missing in most FPS titles. Unfortunately, playing games like this can have a negative effect on other releases. FEAR 2, for instance, hits next week and feels a lot less appealing next to this. :\
