I am currently a level 37, first prestiege in black ops 2, I am trying to find out how to Earn exp for your clan. I have been completing challenges but my clan is still level 1 with 0/100xp
It's not in-game challenges, its CLAN challenges and CLAN operations that level up your clan in BO2. There no challenges or operations at the moment. Keep checking ELITE so you can ENLIST in them. Till then, your clan will remain at level 1.
