Unfortunately the majority of players will not be able to test and play the game soon. If you are not living in Russia. And there is no official information when other regions will be considered because the studio said that they want to focus now on learning as much as they can from the closed beta period in Russia.
There is another interesting fact that to game will have micro-transactions which is visible in the trailer. Let's hope it will not move to the pay-to-win model.
No release window has been announced yet.
