BF4 - Battlefield Friends Easter eggs
Mission: South China Sea
At the start of the Campaign mission called South China Sea there is a Battlefield Friends Easter egg. Right after you can walk out of the cabin, go the first left and stand in front of the first door that is to the left. Stand here for approximately 30 seconds to trigger the dialogue.
There are several things Neebs and Sniper talk about. The conversations are about morse code, pizza, sleeping and cleaning guns.
