Black Ops 3 Fringe Rocket Easter Egg (Original Map Launch)
Black Ops 3 Rocket Easter Egg
Load up the map Fringe and head to the left side of the map, West, and look out in the distance.
You will notice tall structures and a few rockets. The first rocket will launch after a minute or so. I believe this is a reference to the original map launch from Black Ops 1 that was released 5 years ago.
