I mentioned this in the latest HQ Report, but I feel like further clarity is needed.
The "Pre OBT" version on Steam, as noted in its description, is the Asian version.
Our page is currently only a coming soon page.
Our (Aeria Games/Gamigo) focus territories are NA/SA and EU (including some "extra" countries such as Turkey.)
If you are from these regions, you won't be able to play the game on the "Pre OBT" version.
The pages will soon be blocked properly on Steam and we'll be closing registrations on Asian regions for our version as well.
And when will our version be playable on Steam? Well, can't tell you now.
But keep an eye out on our news and reports for both Steam and further news regarding region restrictions.
We apologize for the confusion.
