Not as good as the first FEAR, but still great
I have to say if you haven't played the first one, play that one instead. It's better than this one I think. The first game had you exploring the levels a little more to find power ups and hidden items. This new game dropped that aspect, and everything was pretty much out in view for you.
That said, this one is still great too. I had a lot of fun playing this. The levels are a lot of fun to go thru, and you come across a lot of different weapons to play around with.
I just didn't feel like same attachment to the character or the story as I did in the first game. Something was just a little off.
Oh well, I have to say I had more fun playing this game, and the original FEAR, than I had playing the game I just played before those 2 (Killzone2 - most overhyped game of the year so far in my book)
In summary, if you liked the first game, then definitely get this one too. It explains what was happening a little more with the story and is a lot of fun.
