The teams are divided into two teams to compete for the victory!
Team 1 (escape team) wins if they can escape for five minutes!
Team 2 (the team to beat) wins if they can beat all the people from Team 1 within five minutes!
Something strange happens or doesn't happen every 30 seconds?

二つのチームに分かれて勝敗を取り合う！
チーム１（逃げるチーム）は五分間逃げ切れば勝利！
チーム２（倒すチーム）は五分以内にチーム１の人を全員倒すことができれば勝利！
三十秒おきに異変が起こったり起こらなかったり？
