It´s not as great as the first,but a great game.

The Good:

The Bad:
-Single Player is short

First off,I wasn´t that much into the Ghost Recon-Series before I rented the 1st GRAW and bought it after 1 evening in Multiplayer.After I played months later the Single-Player I was,simple put,stunned.I just had to buy the second!

The Gameplay :
It´s still a mix of Arcade-like Multiplayer and a tactical Singleplayer,both with countless Weapons to choose from.
The Single Player is a lot easier,shorter and not as unique as the first.Because it is almost completely set in desert-like Areas,the Visuals are great,but theres not that much around.It´s still very much fun and you won´t have a second to breathe until the end.Too bad it is extremely short...the first seem to me almost 3 times longer.If you never played GRAW before this is still a good choice because the difficulty is pretty low,which actually means if you played the 1st you see the ending after 2 evenings.
But at least theres a lot to unlock.
The Multiplayer didn´t change that much.On the graphical side,there are moving shadows of the trees and you don´t have the Super-Heat-Nightvision-Goggles anymore which makes the MP a lot more fun overall.The Basics stayed the same which is good IMO.The first is known as one of the best MP-Shooer ever so I prefer less changes over a forced re-invention.And it´s worth playing every Minute.
If you played the first,you can download a lot of Bonus-Stuff for SP and MP.
The Archivements are not as insane to archive now,which let´s you come back for many single- and Multiplayer-Rounds.

The Graphics:
The Characters and Explosions look awesome.You can see everything on you Character,plus little details you don´t expect.Actually,I can´t remember any game with such well made Characters.
But there´s a negative side too...since,like I said before,it´s more desert-based,you don´t have much difference between the areas in the Single-Player.
That doesn´t count for the Multiplayer...you have more places then you can think of and a whole bunch to download too.
It´s said to be the "Best Game in HD" compared to a "normal" TV,but I couldn´t test it until now and I will update this Review as soon as I can.

The Sound:
Stunning,well Mixed,a lot of "own" Style...there´s absolutely nothing bad about it.Just one little question : Why did they use the same Menu-Theme again???

So...:
If you´re a fan of the 1st you bought it already anyway,to all others it depends on what you want.If you play Multi-player a lot this is the right choice,if you want a deep single-player better get GRAW1 first and then think about getting this one.
