Choreography group battle HOW TO PLAY
1. In game (what is 46/64)
Do you see the green keys in the key note list?
They are 4 and 6 in numbers. (Refer to the number pad on your keyboard)
And accordingly 46 means to type in 4 and 6 first then follow the top key note from
the skill list.
Choreography group battle must be choreographed between the group members
so this can be understood as the set rule by the group members for that reason.
