To enter the arena, you need to build a team of 2v2, 3v3 or 5v5. In the past, there were arena managers in Nageland, Fengdaoshan, Garkison and Area 52. You can buy a team application, then you need teammates' signatures, and then submit it to the administrator, so you can queue up in the main city and above to join the arena. But now it seems that 3.0 can't build a team, but you can arrange a practice match or join someone else's arena team to enter the arena to participate in the competition.
