so, if you didn't know, there is a new easter egg out there on the zombie level ascension. it involves the gersch device and ballistic knife. you have to find a generator and find the 4 nodes to activate the egg.

what you need-
gersch device
ballistic knife
good eyes
patience

to start the hunt-
by lunar lander A, and by the PhD Flopper, outside the map is a sparking generator. use a gersch device and throw it at the generator. if you get it right, the black hole opens up and sucks the generator into it and starts the hunt for the 4 nodes.

first node- by the C lander by the stamin-up, look for a snow screened TV. look at it and hold X. the illuminati symbol (unfinished pyramid with eye on top) should appear, then the same voice from the begining of the game will speak again telling that you found the first node.

Second Node- to find the second node you need 4 players. first, buy all perks except quick revive. when a monkey round comes up, have one person be assigned to one perk machine. have all 4 of them look for a red button. when they all find it, everyone hold x at the same time and the 2nd node should activate.

third node- after you launch the rocket and are able to get to the pack a punch room, have everyone get on the pressure plate. after a few minutes the clock should count down to 1, then a nuke should go off and end the round. this is the third node.

fourth node- after you get the first 3 nodes, whenever you ride in a lunar lander, letters should appear in the sky. moving the landers from one pad to the other puts a letter in the sky. to finish the node, you need to spell "LUNA". this is the 4th node.
(thanks to oliboy7 for the word)

here are the 4 node locations. if you need help with them, or know how to do more, leave a post on here and i'll test it out then post it with your name by it happy hunting!
