Since I have played since late 2016, I think I have only saw 2 beta servers up. But of course I was too "noob" to enter it. LVL 50 and 1000 hours I think it was. Too hard! But... I have been playing for over 2 years now and I have reached those goals. I was wondering when the next Beta Server would come up! Last time was the Balloon Warz beta server which was a long time ago... Excited!
