TO get shotguns you need a 160-200 kd but also need good stats deaths and headshots have a slight bit but downs to kills is kd revives boost your chance of getting them faster same with high rounds
Everyone here is right but honestly P-wave has the more logical answer. KD really has nothing to do with it at all. Some girl I knew legitimately had a 42.6 kd with shotguns and blue eyes. I asked here how she did it and she said around when the game first game out all she did was make it to high rounds EFFICIENTLY.
i know people like that too but their co-op stats are good. grief and turned doesnt count fir rank so ignore the career stats
