Valve has officially announced Half-Life 3 during the opening of the Steam Summer Sale, ending years of speculation around one of gaming’s most anticipated sequels. The reveal marks a major moment for the franchise and for fans who have waited through repeated rumors and silence from the company.

According to the announcement, the game is scheduled to launch in November 2026. That timeline gives Valve several months to build momentum around the release while keeping attention focused on the return of the long-running sci-fi series.

The Half-Life name has carried unusual weight in gaming for decades, with each new entry drawing intense scrutiny from players and the wider industry. A formal announcement of a third mainline installment is likely to reshape the conversation around Valve’s future plans and the broader 2026 release calendar.

While details remain limited for now, the confirmation alone is enough to make Half-Life 3 one of the most closely watched game launches of the year. More information is expected as Valve moves closer to the release window.
