Valve’s official announcement of Counter-Strike 2 earlier this week came with limited beta test access for some players. Interestingly, those participating in the Counter-Strike 2 limited beta have stumbled upon hints pointing towards the potential development of Left 4 Dead 3.

Valve’s possible return to game development
Valve boasts a remarkable history with well-known titles such as Dota 2, Team Fortress 2, and Counter-Strike: Global Offensive. They’ve also had considerable success in the AAA industry with games like Half-Life, Left 4 Dead, and Portal. However, recent releases like Dota Underlords and Artifact failed to make an impact, while others were restricted to virtual reality (VR) platforms.
The gaming community has long joked that Valve president Gabe Newell can’t count to three, as games like Half-Life 2 and Left 4 Dead 2 never received sequels. This recent discovery may suggest that Valve is rekindling its focus on game development rather than solely operating as a gaming marketplace. However, Left 4 Dead fans should temper their excitement for the time being.
Left 4 Dead 2 was in production before the Source 2 engine was finalized. While a new game could be under development, the Left 4 Dead 3 references found might be from a canceled version. Dozens of Left 4 Dead 3 screenshots from a 2013 version appeared in 2019, and the gaming community widely believes the game was canceled in 2017 due to the Source 2 engine’s state. The game was rumored to feature eight playable characters and include cross-play and VR support.
Left 4 Dead 3 assets were allegedly discovered in Back 4 Blood, although no evidence supports this claim. Back 4 Blood was developed by Turtle Rock Studios, the same team behind the original Left 4 Dead.
While there are indications that a Left 4 Dead 3 sequel could be in development, it’s best to await an official statement from Valve.
