GRAW 2 is one good tactical shooting game but not quite there yet....
Unfortunately, if you haven't played the first GRAW, you will not know much of the insight of what happened in the prequel. Basically, in GRAW 2, Scott got called back to Texas to save the day again. But it doesn't matter cuz' most of the time you will be given objectives throughout the game and you just have to complete it. There isn't much of the story to it, anyway.
The graphics is well designed. The physics in the game is very detailed even without one of those AGEIA card. However, I found the music to be a little annoying at times. I've been playing the game for 2 days now, I have to admit that the game is quite difficult even at Normal difficulty. (of coz, because I didn't know that you can do a quicksave with "K" button til now so learn the controls now!). The AI is very chellenging as in, they could spot you really quickly even if you are hiding in the higher ground. The best way to go undetected is to flank them from behind or when they are not looking at your direction. From act II onwards, your quicksave is going become your best friend for this game.
Now, the downside about the game is that I find that this game certainly still has rooms for improvement for its Single Player Mode. Right now, it isn't quite satisfying yet. Besides, there are bugs regarding those with NVIDIA Geforce 8 series as playeres reported seeing artifacts in game. This problem shouldn't happen to high-end cards. There are few other gameplay bugs here and there as well. Right now, patches are being processed to fix the issues, though. I haven't tried playing Multiplayer mode though but most players have reported positive feedbacks about the gameplay. Overall, if you like tactical FPS game like Rainbow Six, this game maybe for you.
