This game has probably one of the best Singleplayer/Coop gameplay experiences in the franchise.

It is simply fun to just hop on conquest or breakthrough with a friend or two and have fun, the atmosphere is great destroyable environment is there although it is done better in most BF Games. Then there is Portal, which you can actually host with any rules you want. I play Jungle maps with BC2 US vs BF3 RU, desert maps with BF3 and the rest with BC2 factions.
