Private servers for DayZ have been around for a while for PC, but never for PS4 and Xbox One. On PC, the servers weren’t official but rather, created by PC players who found their own way to do it.
DayZ and Arma developer Bohemia Interactive will allow hosts to make money from their servers. As of December 1, third-party DayZ servers can be monetised, with Arma 3 to follow on February 1 2016.
