Left 4 Dead project lead Mike Booth is working on something new, and if you're hoping it's something like L4D but different in some undefined, hopefully additive way, I have good news: It sure sounds like it.
"I’m excited to share that I'm working on a brand new project—a four-player co-op shooter built on the foundations of what made L4D special," Booth wrote on the Left 4 Dead subreddit. "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."
