Haha. Yeah, I know. "Half-Life 3". The long-fabled, often-rumored, still non-existent third numbered entry in the Half-Life series that fans have craved but never heard a credible whisper of. It's been a pervasive joke in the industry and among fans for years, a stand-in for a thing that doesn't exist and never would.

And yet, for some reason, a lot of people seem to think it's being announced soon. Possibly in the next few weeks. Maybe even today.

You might have seen it. The sudden flurry of mentions of Half-Life 3, some humorous, some quite serious. The surge of memes. A handful of people that seem to have lost their dang minds:

So what's going on? Why do people think Half-Life 3 is imminent, seriously or unseriously? We investigated:

Half-Hope

Half-Life 3 rumors have existed pretty much since Half-Life 2 first released, so that's nothing new. But the last couple of years have seen a steady trickle of interesting little threads that have lead many to believe that a third entry was actually in development, quietly, at Valve. There were vague nods, such as the Half-Life: Alyx team

and a Final Hours documentary that

between 2013 and 2014. We've also seen dataminers pulling crumbs from various Valve releases over the last few years of what seems to be an in-development game internally at Valve

using Source 2. Dataminers have worked out that it's a full-fledged, non-VR, Half-Life game of some sort, that's been in the works since at least 2021, probably earlier. That game is possibly the same one as was accidentally leaked by a voice actor in 2024, who referred to it as

, delving deep into an album cover image and the number 197 for what they believed were even more hints that something was in the works.

But an already simmering pot of rumors turned into a full boil with the announcement last week of new Valve hardware:

, complete with a new Steam controller, and a

. Notably, there were no software announcements alongside these hardware reveals, which is a bit odd given that Valve tends to release new games alongside new hardware - recall Half-Life: Alyx and the Valve Index headset. Around the same time,

of Valve and

began mentioning Half-Life 3, saying confidently that it was planned for a 2025 announcement still. One leaker, who has a good track record of getting Valve stuff right, said back in May that

Go, G-Man, Go

There are so many other weird little indicators floating around that are leading to wild speculation. For instance,

And there was an incredibly silly saga where

that showed he had one game in his Steam wishlist. When

, he responded with an eyes emoji, and then

. Of course, the Half-Life nerds pounced. Keighley then posted a screenshot of his wishlist showing only the game "Dadlympics," but notably, this was added on 11/18, the same day he posted the screenshot, suggesting he's hiding something. Is he hiding Half-Life 3? Probably not! It doesn't have a viewable Steam page! That's not how Steam works! But that hasn't stopped Half-Life 3 fans from pouncing. Seriously, the replies are hilarious.

Whatever you believe is happening here, the reality is that this has resulted in the community going completely bonkers. The Half-Life subreddit is overflowing with Half-Life 3 summoning and hope posts. A quick search for Half-Life on

Okay, so let's say everyone's right, and we really are getting Half-Life 3 announced soon. When? Well, some think it's as soon as today. November 19, as The Game Awards posted, is the anniversary of Half-Life – what better time to make an announcement? We've already passed the anniversary of Half-Life 2, and the anniversary of Half-Life: Alyx's announcement, but that particular anniversary is the reason you're likely seeing so much noise around this today. The other big possibility floated by some is an announcement at The Game Awards,

. That would be a little surprising, given that Valve doesn't need an awards show to command attention with such an announcement. But Valve also has a long history of friendliness with host Geoff Keighley, so maybe it's not so far-fetched after all.

Whatever the case, one thing is certain: either Half-Life 3 is getting announced before December 31, 2025, or an awful lot of folks are going to have egg on their faces come January 1, 2026. I'm personally hoping for the former, but the community has been hoodwinked before with Half-Life rumors, multiple times even. Keep injecting that Hopium, folks. Perhaps the return of G-man is right around the corner.
