Artifact 2.0, the revamp of Valve's failed competitive card game inches ever closer with the announcement of invites starting to slowly go out.
Valve has been blogging about their planned changes, like the removal of card purchases to ensure a more level playing field and no pay to win. That alone could be what allows it to succeed, especially considering the actual gameplay was genuinely fun. Earning cards as you play gives a much nicer feel of progression.
In the latest update post, Valve gave an updated roadmap of what's going on and it indicates they're now starting to send out invites to original owners. The next step after that is to transition to an Open Beta and then release for everyone but we're probably quite a few months away from that.
As for when to expect an email? They said they should appear by next week in your email inbox. It's using a lottery system, so no need to have it installed, at some point you should just get an email and they said they will continue to communicate for the duration of this Closed Beta. Their priority is anyone who purchased before March 30 this year.
There's no restrictions on it, so anyone who gets their invite can show it off as much as they like.
Artifact can be found on Steam.
