I can not now play, for now I don’t have any Steam account.
In a future, if I let me being borg’ed, I would play.
Or, maybe you talk about an hack to play at now without an account.
If you have an early access key, please follow the [post=120886]OP’s instructions[/post], so that you can play now.
If you are “only” an early supporter without alpha or beta access, please wait for Crate opening access to all early supporters, which is intended to happen in January … provided nothing interferes with this plan.
In any case, thanx for your support and welcome to the forums. 
I just activated my copy on Steam… Glad to be here!
