If you're wondering what Undead Labs is planning beyond State of Decay, including its posited MMO sequel Class4, the Seattle-based studio is working that all out right now.
"Discussions of future games are ongoing," said Weathers. "As in, going on now. Thank you from the bottom of all our hearts here at the Lab for making SoD a success, or these conversations wouldn't be happening!"
State of Decay passed 500,000 sales shortly after hitting Xbox Live Arcade, and it looks like it's nearing the million mark; we see 938,000-plus players registered on the leaderboards. That's why those conversations are happening.
