I've been playing the shit out of the extraction mode and love it! It took up my whole weekend (Friday-Tues) and it has been what I was hoping DMZ would be like. Obviously a reach for COD, but they do it well here! Update: 1.5 weeks straight playing, still great!
They need to give us a grunt infantry mode or something. I miss the bf3 and 4 days and 1 when we got different military armies each map fighting each other, and we were just regular soldiers.
