I love it
I like the settings, they seem realistic to me (except for the convienant vent systems). My only problem is the guns, on medium settings atleast, they look very boring, even with the subtle lighting effects.
I will have to replay it when I have a better computer, with everything on max and softshadows on.
I love the slowmo and how fast and clever the bad guys are, they run for cover while shooting backwards with one arm
One thing that bugs me is how there are the health and reflex powerups, I've found most of them, but sometimes when exploring, you take the right direction and end up miles away or at the end of the level.
Oh and its scary for me but I enjoy it.
