I don't have a lot of good things to say about this game. The story itself isn't terrible, but the only time it's every really anything "gripping" is at the very beginning where the game does its best to show us what dire condition the no longer United States is in; and with decent results.
But from there, the game just sort of drifts off into becoming every other first person shooter I've ever played; not that I expected much different.
I'm slightly disappointed in how few of the areas within the campaign actually take place in well-known areas (other than the Golden Gate Bridge, you really never see any recognizable landmarks). So the areas you're running in are very generic; it honestly reminds me of a Left 4 Dead campaign where I'm running through random suburbs and fields, rather than a war-torn America.
I'm glad we don't spend every moment of the game skipping between the Statue of Liberty and the White House, but it would have been nice to see some really defined areas. This isn't a game-breaker, so much as it is a small disappointment.
All in all, the campaign isn't bad, but it's certainly not worth rushing to the store to purchase this game to play it.
As for the multiplayer, the only word I can use to describe it is "clunky". Whenever I'm jumping, it almost seems like I'm in some sort of moonbounce. I also seem to run into and get caught up against a multitude of things that I don't feel as though I'm very close to, which causes me to die far more than it should (because it shouldn't be a problem at all).
I really wish there was a better way to describe it, but movement in this game just seems off. With this being such a new game it may just be something I need to attempt to adapt to. But the multiplayer isn't anything too diverse, and with a lack of game modes that take us anywhere but far from just playing team deathmatch, it really just doesn't seem worth getting used to.
One thing I can say I enjoy about the online experience is that the maps are fairly large, and they don't have a whole lot of places where one can simply camp the entire match, thus keeping it from being a CoD clone (the controls are the exact same, but really, the control scheme CoD uses is fitting, so I'm glad).
The addition of being able to use vehicles (by earning them, rather than by being first to the cockpit) is also a welcome change to recent FPS releases. They're used by earning BP throughout the battle, allowing you to spawn as whichever vehicle you purchase.
But as far as I'm concerned, the online play isn't anything legendary, and all of the problems I seem to have outweigh the few good things I've noticed about it. Personally, I've never been a real expert in the FPS department, so this is more of an observation by the average gamer; if you're not big into FPS games, I would certainly avoid this game altogether. The campaign is decent enough, and the multiplayer isn't the worst thing I've ever played, but the game really doesn't have enough diversity to keep its head above water, IMO.
Is it because I'm not a hardcore FPS player that I dislike the online? Maybe. I look forward to seeing what anyone who has any actual skill with games like this has to say.
