Yea @oxxxxxygen, Operation Enigma is kinda a Easter Egg puzzle thing.
We don't know exactly why it even exists, or why the Team does a puzzle thing like that.
But it's nice and you can win Prizes. 🙂
Website link: enigma.battlefield.com
There are 5 Missions and 5 Prizes.
First Mission is already available!
> first Prize is a trip to Gamescom 2018 in Germany.
> Code to solve it is "27041943"
Other Missios will follow to unlock always after a couple days.
INFO: Some Countries seems they can't win at all, cause you need to choose your country before you can start the Mission and there are just a few in the available list.
I mean you can choose another country and just complete the Mission, but not sure if you can even win then.
Counties that are available, listed in the pic. below!
