Easter eggs are meant to be hunted...we have found many on this map but none of which are large scale. There are many little objects like electric sockets and mannequins that undergo a "physical" change after a bullet contacts them, some change back some do not but either way they do something that sticks out from other objects in the map. Whether these are relevant to a large scale Easter egg is unknown. Nuketown is a small zombies map and in the past maps Treyarch has scaled each of their larger Easter eggs steps and game-play to be comparable to their partnered maps overall size and playable areas. My Theory is that this map is meant to be a prelude to TranZit and only has audio recordings that help build the baseline for the new story as well as the connection to the future maps and the Characters (maybe this is how Marlton is found?!?!?! 4 characters to 4 DLC packs) Maybe Treyarch is focusing on Large Easter Eggs only being in the Tranzit Mode and theres smaller easter eggs on survival that give you extra game play perks/powerups like that stupid yellow shed and the population counter changing it. (not to say that the symbols, shed and clock don't connect for a smaller Easter egg) Maybe it is there we just need to stop thinking it has insane steps with many things to do and look smaller. For example that we may need to control certain numbers of zombies alive or killed at certain times with certain weapons to make the next step unlock. (just thoughts guys seems practical to me and treyarch is most likley dedicating more time to tranzit easter eggs than survival bonus map easter eggs) Let me know what you think.
