The only one that unlocked for me was the one for getting three headshots in a row. That was on the anniversary playlist on an anniversary map. Theese are the others I should have gotten but I did not.
Kill an enemy with a gernade they stuck you with. This was done on an anniversary map.
The jetpack beatdown thing. This was done on an anniversary map.
5 splatters. This was done on the noble map tempest.
Am I doing something wrong or ius everyone having this problem?
