(adsbygoogle = window.adsbygoogle || []).push({}); Hello NGU, so I was playing zombies with a friend yesterday, I was with my account and he was with his (split-screen), and we played zombies for about 5 hours. I had the 2 bones rank before starting and now my rank has gone down! His rank went up, but mine went down! How is that even possible? I made about 1000 kills online. Please help me? Thanks.
