Hmm, where to start...
The multiplayer and gameplay itself is good. Some maps are very large and feel like a larger amount of people playing would be better, like 32 people as opposed to the 16 it allows. Even with the addition of vehicles the larger maps they dont make up for much, other than coolness. Campaign mode allows you to set your difficulty level, I chose Normal, not hard at all really, I couldn't imagine easier modes. If you plan to play online and do well, practice, especially if you played through campaign thinking online would be a cakewalk, its not.
