this really could be one of the biggest easter eggs treyarch has ever done i mean one that night unlock a new part of the map thats impressive this is pretty cool dude

iv been looking through the codeing for call of the dead or *nazi_zombie_coast* and i am almost 100% sure there is nothing else to be found. iv found everything that makes the original easter egg run but there is nothing in it about an ice cave or anything that even sounds remotely connected to another easter egg.They even have a whole seperate .gsc just for the easter egg. Dont you think thered be another one if there was another egg?
