Campaign isn't nearly as bad as ppl claim,Coop missions are some of the most fun you will have with a friend and Online.
When i heard all the bad things about Battlefield's campaign, I was bummed. I love fps-war campaign's, so I played it anyways. By no means is it inspiring or innovative, but it's fun nonetheless. The locale is varied and beautiful, and the mission objectives change enough to keep you interested. It's only 4 hours long, but that was expected.
The hidden gem of BF3 is coop. Me and my buddy have spent hours coordinating attacks, driving helicopters, and silently securing targets. They provide a huge challenge and are very gratifing. Not only that, playing them will unlock weapons for multiplayer
As everyone knows online multiplayer is the reason people play BF 3, and it's everything that it claims to be. Larger maps, gorgeous graphics, fun game modes, realism, and the best part NO LAG!!! cough COD cough cough. Overall, if this was a game you wanted, you will not be disappointed.
