Finished the damned thing this morning. I tend to agree with Gamespot... 8.5 out of 10. It had a nice, detailed, and long single player campaign, which is a big plus for me as I don't do much shooter multiplay (too much twitch, I usually don't even see what's killed me a dozen times). It was a damned scary game at times, sometimes (especially after a glass or two of wine) I just couldn't keep playing it. Too much adrenaline.

That said, it definitely had some flaws. The "boo" factor that's so nifty can also at times get very old. Eventually I found myself rushing back and forth from point to point just to trigger the spawn events. The lack of open or outdoor levels confine you to a pretty linear transit of what is already a linear game. The tight confines also help disguise what is essentially a pretty weak AI. There are no gang tactics, no flanking, no running to get help, etc. Again, because of the nature of the game, it's not glaringly noticeable, but in the post-Half-Life universe smart baddies are half the fun.

The storyline was very immersive, and unfolds nicely, but I would've liked a few more main objectives. I wanted a little more redemption, maybe an extra rescue or two.

Still, it is a very good game, definitely a healthy "check-your-brain-at-the-door-and-blow-stuff-up" bit of entertainment. If all you want to do is run around and blast demons and devils, you could do a whole helluva lot worse.
