If you've been struggling to get this achievement I have good news!
All you need is one other person, I obtained this today with one friend.
Just to make it simple, ill write step by step what we did. Firstly we were not in a party in-game, we went into matchmaking separately.
Change the Data Center to Japan West or any other, that is just what we changed it to but i'm sure you can use others.
Both match-make into a game mode that has no one from your region and also has an evac at the end of the match, there should be plenty.
When you get into a lobby it should say waiting for players, but because you have no other players in your region it will do one of two things, either put you in a match out of your region which doesn't happen often, or into a match on your own with your friend.
Just win the game and wait for the evac prompt then kill your friend and it should pop.
If you leave bad feedback please also leave a comment to go with it.
