Check the discord.

Basically, you and your teammate join or host a lobby with your opponents. You start a standard game of squads and whichever team has the most kills wins. If it is a tie, then the duo that survived the longest wins. For more in depth rules, check the discord above.
The games are best of 3. After a team has won 2 out of the 3 matches, both teams must direct message me or post the scores in the results text channel located in the discord server so that I can update the bracket and allow the teams to continue ahead in the tournament.
