Sound when u act farm tv and buy b23r first time

[funky419]

So I will admit this is my second call of duty, first zombies. I wtch ed a vid of shangri la and when they were leaving the first area of the map opening a door or moving rubble i forget the same noise comes up when you activate the farm tv or buy the b23r the first time. I guess its the same on moon maybe a few other maps? It seems that in previous games the noise was referring to opening a door or unlocking a new area. I am starting to think it might not be a coincidence that those two different actions make the same noise? Just a thought and was wondering if anyone can think of a third place they have heard this noise? it is 3arch and all.

I have activated both in a game where both sides of the egg were done. In that same game i tried to get the lights at the laundry but i just melleed it and nothing happened. I wasnt really EE hunting but we played til round 39 and had everything built, visited pap a bunch and all four players were almost everywhere on the map and no one noticed anything unusual. Although we could see the orange and blue lights on the tower i realized one of the players in the game didnt build the nav table yet.
