As timeline states https://beyond-the-void.net/index.php/timeline/   Open beta will be here for everyone to play in just a month.  Since I cant log to my ETH wallet i did not even bother signing that message to pay this closed beta. 1 month form now game will be more ready for me and anyone else to test.  I also hope ETH will be way more ready as it is now when game will be fully launched.
