For PC gamers around the world, Half‑Life 3 is undoubtedly the game we’ve all waited far too long for — many even consider it a “daydream.” Yet ever since Valve rebooted the series with the 2020 VR title Half‑Life: Alyx, the momentum behind its successor has grown stronger and stronger.

The ending of Half‑Life: Alyx cleverly retconned the conclusion of Half‑Life 2: Episode Two, seemingly freeing Valve from the narrative impasse that has blocked the series for years — and giving Half‑Life 3 a real possibility to exist. Add to that various Valve insiders in recent years claiming that the game is actively in development, and now a bold fan theory argues that this legendary sequel may soon reveal itself.

The leaker in question presented a theory based on the schedule of the Steam storefront homepage — they believe Half‑Life 3 could be unveiled as early as November 18. Valve normally uses large banners on the Steam home page to promote major events and sales. But fans observed that between November 18 and December 8, no activity was scheduled on the Steam homepage — a striking blank for Steam.

Further, Valve moved its usual November Steam Autumn Sale up to September that year — when asked, they said it was intentional, but gave no further explanation.

These irregularities have led fans to speculate that Valve may be clearing out prime homepage promotional real estate just in case they’re gearing up for a Half‑Life 3 announcement. The date of November 18 is given extra weight because it’s the anniversary of Half‑Life: Alyx’s announcement day.

If Valve were to choose that date to announce Half‑Life 3, they could then direct momentum toward the upcoming The Game Awards (TGA) on December 11 and unveil a full trailer there. Though this might be a guess built on coincidences, given how Alyx’s ending left that big cliff‑hanger for Half‑Life 3, it seems unlikely Valve would just leave things hanging again.

It’s worth noting that well‑known Valve insider Tyler McVicker recently stated that a trailer for Half‑Life 3 is currently in production, and that Valve’s approach to announcing a trailer and a game release differs from other publishers — in his words, the trailer reveal will be very close to the release date (much like what happened with Half‑Life: Alyx). McVicker emphasised: “Let’s keep an eye on November.”

With the date of November now matching both fan speculation and insider hints, we could be in for a surprise this month. Stay tuned.
