Here is a Q&A about new event.
Q: Sir, what’s single-elimination? Will there be new gameplay with a knockout system?
A: No, it’s the new multi-team PVP. [Multi-team PVP] is more about strategy because it will be a maximum of 3 teams for each participant. After a team wins, it can continue to attack other teams. That’s why it’s single-elimination. You have to plan wisely to win!
Q: It sounds like a combination of Arena and multiplayer sections. Except for the different officers and troop formations, are there other differences from a standard arena?
A: Of course, there are. [Multi-team] does not mean all three teams are available at once. Our commanders must reach the required ranks to unlock the second and the third team, and the slots for the teams will be locked again if commanders fail to meet the requirements. (The number of teams allowed to play is different depending on the rank.)
