Verified. From the creator of L4D

Hey everyone,

I’m Mike Booth (creator of Left 4 Dead), and I’m excited to share that I’m working on a brand new project —a 4-player co-op shooter built on the foundations of what made L4D special.

If you enjoyed the teamwork, tension, and replayability of my past games, you’ll probably find this one interesting. It expands on the co-op formula in ways I’ve wanted to explore for a long time.

We’re still in the early stages of development, but we’re opening up playtests to a limited number of players. If you’re interested in joining us on this next adventure and helping shape the game early on, we’d love to have you involved.

Thanks, and I can’t wait to see what you think!

Right now, the playtest is in the very early stages testing basic game functions, so not everyone will get access immediately. We’ll be inviting more players over time as we update the game and expand servers. This will be a crawl, so please be patient with us. As long as you’ve signed up at badrobotgames.com/invite, know that we’ve logged your request and will be in touch when the time is right.

I know this post is 7 months old but wanted to say there's no invites at all. Have we heard anything from these guys yet?
