This achievement can be boosted with a 2nd controller, or with a friend. Whenever the game has started, no one can join in the current round. So simply set up a public battle match. Immediately ready up by pressing

. Then when the match starts, wait for the countdown to finish and immediately either suicide or kill the 2nd player. Repeat for another match and then ready up again for a 3rd match. Hopefully no one has joined in when the 3rd match starts, and you can get your achievement.
- If players join while you are ingame, select their name and start a vote to kick them. If you keep kicking players with both of your accounts before a 2nd random has joined, you can keep the lobby to yourself.
-It HAS to be a public match (either casual or competetive)
-It HAS to be 3 consecutive matches in the same lobby. Doing 1 win, then backing out and doing 2 more wins in this way does not count.
Alternatively if you cant do 3 consecutive wins without anyone joining, you can lock down a lobby with 8 accounts/controllers. (guest accounts work)
