idk O.o

how many downs do u have and kills

u guys know how the ranking works i had the shotgun emblem then got deranked to knife and shield emblem "(

there isnt only one way to get that, but you need to get constant better than you are... also everyone did the round skip glitch gets it instant, so if you get to round 200+ you will have it
basically theres a KD as in mp, try to get down as less as possible and survive into higher rounds...
also you can boost it in custom games and start at round 15 just pack a punch the pistol and get like 100 kills no death, then leave game and do it again... after a time you will have the shotgun rank...
(sorry 4 my bad english)
