Campaign is real dope, I'm liking how you can basically assemble your own gun out of all the parts of other guns, it feels a lot more polished and complete then the first game, the co-op tactics flow more naturally and feel less forced, online is cool, 4 on 4 warzone has different objectives throughout the match that your team has to meet (blowing up the package, taking out targets, taking intel), there's also straight up team death match both 4 on 4, and teams of sets of teams of 2 going up against each other (thing Wing Man from Gears of War), custom masks are cool too, you can log in at armyoftwo.com make your own mask and import it into the game as well.
