Release Date Black Desert Mobile Global
The App Store has a release date of December 12th. Unfortunately, this date has not yet been confirmed by the developers. (There are such rules in the App Store, you can’t mix games without a release date and developers indicate the approximate date, then simply edit to the date they need).
But December 12th fits our prediction: the winter of 2019, and also Thursday, all releases were released on that day.
