Riot’s fighting game, 2XKO, differs from many in this genre by not utilizing a peer-to-peer connection. Instead, it has a server-based rollback netcode that helps stabilize the connection when one of the players is having some network issues.
So it’s even more important than ever to have a stable connection. So if 2XKO won’t connect, matchmaking keeps failing, or you’re stuck at login, the first thing to figure out is whether you’re dealing with Riot-side downtime or a problem on your end.
