It took me a long time to finish the Assignments from B2K, but I guess I wasn't really trying that hard to get them :p The weapons in this DLC sound more to my liking and I will get CQ as soon as it's available on Xbox.
I'm done with all assignments except for the JNG-90 and the M5K. That's only because I can't get into Gun Master or C-Dom matches yet. Stupid DICE/EA fucked up some how and made it so only UK servers are working for the Close Quarters maps.
Last report said there was no ETA on when it'll be fixed either. Maybe someone else could elaborate on this.
