Hi there!
Yesterday I was doing peacekeeper quest. On the map of Zeebrugge I jumped to the ship and waited for the kit. Started to break windows. When I stabbed that window 5 times, I heard some whisper which we hear when we pass a part of quest for peacekeeper.
Pic attached. Can it be a a clue to the another easter egg?
