If you are trying to get the crossbow and ballistic knife gold, then your in luck. If you have notice by now it may not be easy to get it gold just play playing public matches. So here are some tips. First make sure that you have either the crossbow or ballistic knife unlock or else this won't work. Then simply go to party games and start up sticks and stones and only use the gun that you are trying to get gold. I personally got them both gold in four hours. Also don't be surprised if your ballistics knife kd is 100 or some other crazy kd. For some reason when you die with the ballistic knife it downs your crossbow's kd not your ballistic knife's.
