January 17, 2020 Valve says no Left 4 Dead game is currently in development.

While recent leaks have suggested movement on the Left 4 Dead 3 front, Valve has now confirmed in no uncertain terms that no follow-up to its classic co-op FPS is in the works. The company has confirmed that it’s worked on a L4D sequel in the past, but there’s been no further development on the idea in years. “We’ve seen rumors to this effect for the last couple of months,” Valve tells IGN. “We did briefly explore some Left 4 Dead next opportunities a few years ago. But we are absolutely not working on anything L4D related now, and haven’t for years.” The company adds that “It’s clear some people are having fun creating misinformation to spin up the community and other outlets. Unfortunately, for now a new L4D game is not something we’re working on.” Though the statement shuts down rumours that L4D3 is back in development, it partially verifies the claims from YouTube channel and fansite Valve News Network that the studio started making Left 4 Dead 3 “in late 2011 or early 2012” before cancelling it in February 2017.
