So alot of people love to do camo grind and to get interstellar you have to max 36 weapons. Most of them gets unlocked easily. But some of them doesn’t unlocks.
So i have tried every thing Activevision support asked me to do. Which included, reinstalling the game, reinstalling the licenses, and after all these steps nothing helped me.
So finally I found a way which can helpful to alot of people. So here is the trick:
Add one of your friend into party, if you dont have any you can ask someone randomly to help you. So after joining in party, ask your friend to get to zombies mode, ask that friend to select the gun in the loadout which is not unlocking for you. After that go to game, ask your friend to drop the weapon. Make that one your primary weapon and do the exfill. Just make sure that you exfill with the gun in hand which is locked for you. As soon as you will exfill, go to loadout and that gun will be unlocked for you.
So i help this will help you alot
