We both live on Korean soil and have designated the steam area as Seoul, South Korea. And my friend doesn't have a network error, but I'm the only one who does, so if my friend digs a room for two, invites me, and tries to enter after being invited, I can't enter by saying that the room number doesn't exist. When I try to sell a room, the network error/none repeatedly pops up and I can't create a game room.

Hi 꺄악 더러워 ,

Did you already try to change the region? May be you both are located in different regions and that cause this issue. Please, send us a note to team@metapublishing.io and we will try to help you.

I bought a biped and played with my friends many times and never had a network issue, but when I try to play a biped with a new friend, I can't enter the game with no network/error. What should I do? I've tried changing the steam area, but I still get an error.

HordeCore servers are on already and you should not experience any issues with it.

СЛЫШ мета кок, денюшку за бипет свой получил? А теперь быстро иди и мультиплеер чини, потому что в стиме есть пометка "кооператив по сети"

TURN HORDECORE SERVERS BACK ON PLEASE
