Call Of Duty Zombies History!

Since Call Of Duty: World at War, Treyarch has been puting clues to discover all the secret zombie history. Not many people know about it, but there is one reason that explains every map and every easter egg of zombies.
I will showing you all the meanings of the call of duty zombies things, starting from the guns and perks to finish with the most secret thing.

I will start explaining the meaning of every perk of zombies.

First Perk.- Quick Revive!

The quick revive is the representation of the help that the secret group provide to Doctor Maxis, beacause Maxis had a secret plan but we don't know why it went wrong.

That plan was to revive the dead person of Shi No Numa. This plan went wrong but Maxis had a plan B, that plan is directly conected whith what hapenned under the sea.

The quick revive provides you the capacity to revive faster to your teammates and if you are playing solo the machine revives you if you fall down.

That's because Maxis died in Origins, and his brain was saved by Richtofen as you can see in that image.

And it revives you beacuse it's explaining how the secret group wants to revive Doctor Maxis. 

And soon I will explain what does this mean :
