Ok well a person from treyarch who acually works on the story but the group from zombies had them work on part of the map and story while they worked on the next two map packs{3-4} but this is something he talked about along with lots more{I will have more posts later tonight about the rest of the things} but this is what he said
He said that PHD Flopper will be returning but it will be nerfed{Dont know how they nerfed it} and their is another new perk call something i cant remember the name but heres what it does it doubles basicly everything on curtain guns that you buy off the wall or get from the box it gives you more 2x ammo and 2x power and everything else
and Another new perk is the perk we saw in the video and what it does is when you reload it electriccutes zombies around you and the last perk is called bandilier what is does is when you kill a zombie it gives you just a little bit of ammo not very much at all but it will help becauase every bullet counts but it will only work with bullet type of guns not 115 or wounder weapons! That is it about the perks i have a lot more info coming later!
