Not a bad game, but nothing you haven't seen before.
A solid all round shooter, decent attempt at physics, decent graphics and good sound. Nothing that will blow your mind though. Multiplayer is fairly good. Again, nothing you haven't seen before though. Doesn't really move the genre forward from Battlefield 2 on the PC, a game that came out 5 years ago.
Cons:
Not really engaging. Controls are fairly basic and lack depth. It reminds me of a PC based FPS from earlier this decade, only with better graphics. Single player mode is entirely forgettable. It's playable, but on the whole it's boring with only a handful of new ideas.
Overall:
I'd recommend a borrow first before buying this game. I feel the whole FPS genre has gotten stale and probably peaked with Call of Duty 4 in 2007. Last few big name FPS games have fallen short of the hype in my opinion.
