15/12* is the date actually. And there is no price for this Alpha, invitation only. You may buy access to other Alphas and Betas in future, prices are unknown as of yet.
Subscription being considered is $15 a month.
Alpha 1&2 and Beta 1&2 are purchased keys, they do NOT require a subscription to play.
Thank you UnknownSystemError. @NightSongGr did that answer your question?
