PUBG: BATTLEGROUNDS

This is a retroactive achievement: if you satisfied the requirement during the period of Game Preview, it will unlock automatically once downloaded the complete game.

To unlock this achievement, you have to be the winner of a Squad Match. You can play either third-person or first-person modes. The achievement will pop in both cases.
You don't need to be alive to unlock the achievement. If your team is the last one standing, everyone in the team will we awarded with the achievement, even if one or more of you are dead.
I highly recommend to play with 3 friends to coordinate together your movements, balancing your equips, etc. If you try to find a game alone, the game will automatically match you up with other players. They can be a team made up in any combination from: a whole team of alone players like you, or a team of 3 friends. Like in the case of Duo, it's harder to win if you don't know what your allies are doing, but not impossible of course. Just remember that you will find enemy teams made of up 4 players who probably are talking each other...
There is also another way to obtain this achievement. You can enter a Squad Match with an undersized team. In the main menu inside the lobby, below Squad, you will find "1-Man Squad", "2-Men Squad", "3-Men Squad", depending on how many players are present in the lobby with you. For example, you can decide to start a Squad match with only 2 friends by chosing "3-Men Squad". In this way, you are going to face enemy teams made of up 4 players, but the decision is up to you and, for the achievement, a victory will count as well.

I started a one-man-squad match on the oceanic server.
(Depends on your time zone, choose a server, where nobody should be)

After 6 or 7 minutes, the lobby started and I was the only gamer in this lobby.
As the plane flew over the beginning of the take-off line, the match ended and this achievement popped for me.

I hope that this method will work for other players too.

P.S.; If you vote negative, write a comment or send me a pm for your explanation, please.

Find very easy way to obtain this achievement.

After hours of trying I can't win single game, everyone killed me by one shot... spend 200h+ hours, after this solution 3 remaining cheevos obtain in cuple of hours

I change in settings multiplatofrm by turning it off.

Than start game, after 3 min you will be asked to turn on multiplatform - say no, next question change server - you can or not, doesn't matter - done on both and it worked as well.

After about 10/15/20 min (don't know from what it depends) game start, you are the only player in plane - 8s and you win the game, achievement pops.

If game load more than 25min just abort and start matchmaking again.

Happy hunting!

Just play Casual Quads it's only 12 real players and 88 bots you can only play 3 a day but with only 8 real players to worry about its an easy chicken dinner in deed
