Fans of the iconic Half-Life series are buzzing with anticipation as some Reddit users believe they may have pinpointed the date for the announcement of the long-awaited Half-Life 3. According to a post by a user on the r/HalfLife subreddit, November 18, 2025, could be a significant day for fans eager to hear news about the sequel.
The speculation arises from a noticeable gap in Valve’s schedule on the Steam Store, specifically regarding the prominent top banner typically reserved for major announcements, sales events, or new product releases. Historically, Valve has utilized this space to generate hype, such as when Half-Life: Alyx was announced in 2019, and for the unveiling of the Valve Index VR headset.
Adding weight to this theory, another user, BeeBeeTheDev, shared an analysis indicating an unusually long absence of the Autumn Sale banner between November 18 and December 8, which has been a customary period for such promotions. Interestingly, Valve has opted to move its 2025 Steam Autumn Sale to September. In their announcement, they cheekily remarked that they had made this adjustment “intentionally,” sparking even more intrigue about their plans for November.
There’s also the possibility that Valve might reserve this November date not only for Half-Life 3 but potentially to announce the new Valve Deckard/Steam Frame headset, creating a high-profile dual reveal.
While Valve has yet to officially confirm the development of Half-Life 3, the buzz has been buoyed by comments from insider Tyler McViker, who suggested that the game could drop before the end of 2025. The excitement is further fueled by recent rumors, including data-mined assets and leaks linked to actors believed to be involved with the project.
As fans eagerly await, the prospect of a new chapter in the Half-Life saga brings a glimmer of hope for a franchise that has captured the hearts of gamers for decades.
