It's been ten years since the Half-Life series last showed life, with the shocking conclusion of Half-Life 2: Episode Two. And surely, we thought, Valve wouldn't leave such a stunning cliffhanger untended for long. Surely, that heart-wrenching finale meant that Valve had a proper finish already cooked up, and the infamously long Valve-time waits between games would be a thing of the past. Surely.
The decade since has not resulted in Episode 3 or a proper Half-Life 3. But much has happened: through both official channels and clever hoaxes, our hopes have been raised up and then dashed on the rocks, again and again.
We've recently updated our list to include what has come to light in 2017 thanks to a Reddit AMA with Gabe Newell and some major revelations from ex-Valve writer Marc Laidlaw.
Here's every Half-Life 3 hoax, rumor, and leak we've collected.
May 2006 – Confirmed
The fun begins not with a hoax, but an actual, official announcement: Half-Life 2: Episode 3, in time for Christmas 2007! There was even talk of Episode Four! Because sure, why not? Gabe Newell said episodic releases would be "pretty frequent," ideally spaced out by six to eights months. By my calculations, that means we're just about due for Half-Life 2 Episode 16.
January 2008 - The faking begins
Half-life 3 fakes started pretty much as soon as The Orange Box was out the door. Just a few months later, this . It was obviously a fake, but it was a sign of things to come: the years of hoaxes, leaks, rumors, and wishful thinking that led to this article today.
October 2008 - Two million copies?
Just as things were getting into full gear for the 2008 holiday season, Valve's Doug Lombardi told Videogames Daily that Valve "may [show Episode 3] at the very end of the year." Emphasis on "may," obviously, as Valve ultimately had nothing to say. He also expressed worry about over-committing to Half-Life 3, saying that if the studio got too deep into it, "We have to sell two million copies or else we're fucked." Two million copies, you say? I suppose that seemed like a lot back then.
July 2010 – The blob shake
Half-Life 3 references are found in the Alien Swarm SDK, in object properties like "Ep3 Blob Shake Position," "Ep 3 Fire Cover Position," and "Ep 3 Blob Brain Cover Position." It obviously wasn't proof of anything, but we were so hungry for a new Half-Life by this point that it was taken as rock-solid evidence that Gordo and co. would be making their return any day now.
May 2011 – Bad advice
"Combine Advisor – Roaming" code is found in the Portal 2 SDK. Advisors had previously appeared in Half-Life 2, primarily in Episode Two, but that particular slice of code was not in the Episode Two SDK. It was new! And then Valve removed it! Clearly there was something to hide, although by now probably everyone involved has forgotten what it was.
July 2011 – A small, strange room
A brief, very strange video clip containing a hex string led to the discovery of a small Half-Life 2 map on Megaupload. Hidden in the tiny, decrepit room is a heavily distorted image of a face and an audio file that, when fed into a spectrograph, revealed... well, not a hell of a lot of anything, really. The Half-Life connection at that point was pretty thin but that's the conclusion everyone jumped to because we were all so desperate for some crumb of hope, and it did have the distinct look of an ARG in its early stages. Alas, Valve kiboshed the idea in short order, and that was that.
December 2011 – T-shirt guy
All I'm saying is I saw this at a local game developer event worn by a Valve employee. http://t.co/8trtqZ2o #HalfLife3 #ValveTrollingDecember 2, 2011
Some guy, who some other guy said works at Valve, wore a Half-Life 3 t-shirt to a "local game development event." The wearer of said shirt was cool with having a photo of the shirt taken, although not his face, which is perhaps telling—although whether it's telling us that the over-sharing Valve employee wanted to keep his identity on the downlow, or that he was just some rando who dropped a fiver at a t-shirt shop, is impossible to say.
December 2011 – Wheatley gets involved
Valve whipped up a video for the 2011 VGAs featuring Wheatley of Portal 2 fame, complete with Stephen Merchant's voice, and also some science-y looking guffola in the background. Among it was a spot of Russian text which translates in part to "Lanthanum," derived from the ancient Greek "lanthanein," meaning "to lie hidden," and written, "λανθανω." That first character look familiar to anyone? Sadly, Wheatley didn't win his award, and we still don't have the game.
December 2011 – Black Aperture
The last month of 2011 was a big one for Half-Life 3. A couple of weeks after t-shirt guy made his appearance, a mysterious site appeared at black-aperture.com bearing a very similar logo, along with branding for Valve, Steam, and the Source engine. Alas, the hoax effort didn't even stand up to the cursory inspection of a domain whois check, but it's to the credit of the owner that the site is still up, now bearing a blurry ".../3" image.
