Secrets in zombies

In zombies in Call of Duty: Black ops there are many different secrets. One of my favorite secrets is that in every map they have three "meteors" which you hold X while looking at one it will make a buzzing noise. Once you hear this noise you know that it has been ativated and once you activate all three a secret song will come on. Except in one map "five" you will have to activate three Telephones. In dead ops arcade you will not be able to do this at all.


Another secret is that some weapons that you get out of the box you need to do the Easter egg. Like Call of the Dead with the V-R11, or Shang ri la with the raygun and "Baby gun?", and also with Moon and the Gersh devices.
