Although just a rumor and nothing set in stone, someone from LostArkDB had a chat with a Smilegate employee and they mentioned that the next Closed Beta for the Korean version of Lost Ark Online is scheduled to start sometime in June or July. I'm totally excited for another beta of Lost Ark since the PC gaming market in both Korea and Japan has been super slow and dead.
