Nothing new to the FPS genre, but certainly unique !
As a free to play fps, this one is holding up very nicely when compared to the rest of the genre.
Level design is very good and graphic is as good (if not better) than the other fps around.
The "free to pay" aspect is very well balanced (I play with the basic gear and still am able to be competitive). You don't become a god just because you fork over some cash. You still need skills.
The review is not fair toward the hardsuit ion my opinion. It is hard to get used to the clunky movement (Took me about 4 hardsuit before I got decent with them), but for the firepower you get it has to get a drawback. I personally am a hardsuit enthusiast in all my games and I must say it can be a serious asset to any match.
Bottom line : Do try it. It's free. You will not lose anything :)
