I play more campaign than online so i cannot comment on the online aspect.
I am so far thoroughly enjoying this. A good heart warming story. The combat is great. It uses the frostbite engine so gameplay/graphics is the same as battlefield so no one can say its bad.
It isn't door breach after door breach. You maybe have to do it once or twice a level if that, and the really good thing is if you get head shots during a breach you unlock different ways you can preform the breach.
The only criticism is its slow starting. The levels are very short and a lot of cutscenes, but when it gets going the levels are large.
It is definetely a good contender to get you warmed up for the other upcoming titles.
