Nowhere near as good as GRAW1
So where did it go wrong?
First of all you can now command the entire team like in R6 Vegas (awful game) so the team then becomes a decoy that can usually look after itself rather than individuals that you you are fighting to keep breathing. It's also pretty linear. In GRAW1 you could survey the tactical map and plot different routes which was a lot of fun as once your confidence grew you could pair up with a wing man and send the other two ghosts off on a different route to flank the enemy. In GRAW2 you think you spot a route to do that only to get warned you are 'leaving the zone' = game over... The two worst things though are the option to choose the difficulty level and the possibility to save. In GRAW1 (unless I didn't notice it) there was no difficuty option - it was just realistic and the fact that you only had checkpoints to save at made your teeth itch as you tried to keep everyone alive between them. It also forced you to go slow and be tactical but in GRAW2 you lose the 'care' factor as you can just save (most of the time) and know you can reload if you die. Another gripe is that both command interfaces are now more clumsy and the AI is poor as you can walk straight past some enemies with no reaction. That sort of thing can get sorted by patches though. Finally, the music is not so good when in GRAW1 all you got was ambient synthesiser tones.
Where did it go right?
You can use fixed guns and there is a wider selection of weaponry (although the interface is clumsy, it and it is difficult to compare options). Unfortunately it seems the team also have limitless ammo now. The assault/recon modes are not a bad idea but are not well implemented. For example in assault mode a cover instruction will force suppressing fire - which is a bit pointless unless there is actually an enemy to shoot at.
End of moan, I think. I can't see any point in playing this more than once but GRAW1 for a fifth time is a distinct possibility.
***UPDATE***
As I near the end of the game (and give up on it), a quick update:
The above holds true apart from the last mission, which is practically impossible - especially if you do not have a sniper rifle for this mission (it is not your default kit). I now give up on the game as this is becoming so tedious to try and complete it.
***UPDATE2***
I have just played through a second time and decided maybe I was a bit harsh first time around; it is really quite good. However, it is very linear and the last mission is basically a solo exercise with a sniper rifle while leaving your squad out of harm's way.
