When may I download the game? I just bought it but I cannot download anything yet.
If you got the Beta, you should have gotten a key, which you can enter in steam.
I bought the digital download. The $33 one. None of the purpose options said “Beta” on them. Which option should I have chosen to be able to get into the beta?
You can only get Beta access on the Early Access Tier or higher, iirc 110$+
Customers on a non-Beta tier will get to redeem their keys on release day: 2nd September 2021.
