What Treyarch didn't want you to know...the zombies Ranking system. It's been a mystery for a while now and nobody really knows how it works. Truth behold, It's rather easy. In this post you will:
A.Figure out how to rank up

B.Figure out why you get De-ranked

Now go to the next section and start learning!

Think of the Emblems and Slashes like Multiplayer. The Emblems are prestiges and the slashes are levels. You get 5 Slashes per prestige. After the fifth slash, you basically prestige. The prestiges are:
Prestige 1-One bone
Prestige 2-Two bones
Prestige 3-Skull
Prestige 4-Skull with blue eyes
Prestige 5-Skull with dagger
Prestige 6-Skull with blue eyes and dagger
Prestige 7-Skull with shield
Prestige 8-Skull with blue eyes and shield
NOTE:People have claimed to have a skull with shotgun and skull with blue eyes and shotgun. This would explain Prestige 9 and 10 but this HAS NOT been confirmed yet. If anybody does have it message me on xbox :"Tig Lobbys" so i can confirm the shotgun emblem.

Now the deranking system is a little weird. It is true that is based off the players skill level (as confirmed by the creator of BOII on his twitter) BUT AS A TEAM. So if your partner gets downed 50,000 times then you're most likely going to go down a rank. Hope this helped and please reply and tell me if this helped you
