For kai run player :
you can use the other setting such as "the key body setting"
It means that only one player is the key body so only he can open the door.
Despite someone ,who are kai run player,go to the safe room,he still wait the key
body to come to open the door.
i know "VS01 2018瘋狂高對 。8V8" is using these setting
For out game(走埸) player :
firstly,you must know why they out game.then,the problem is "lose=out game".
since they always die fast ,so they can not make any fun in your ser.
no fun no play~that i suggust you can change the basic hp to 200 in everyone(exp setting is still (+80hp) here),then they will not die easily.
so no more kai player out game la!!
it is good ser .>~<.
