For the campaign challenge expert, the first task is to complete a mission without firing a gun (Melee, grenades, and gadgets only). I just completed the entire mission of Operation Ember Strike without firing a gun, using only knife, grenades and the drone and did not get the completion.
Ive been looking online and apparently when you shoot a gun in the previous mission it'll bug out and carry over. Same with other challenges too. Ive read that if you go to the main menu and try to do the challenge it'll be complete as you didnt shoot in a mission. Hope this helps
Unfortunately that didn't work. :(
Same issue here, i try that on 2 missions, and does not get the skin.
