Way back in 2012, the Black Mesa mod for Half-Life had lofty plans to entirely rebuild the game in the Source engine.

If you'd been awaiting the release of much-anticipated the Xen levels, we have bad news—it's been delayed again, despite the mod moving from a free-to-play to Early Access model in order to take on new staff and strengthen the development team.

"We are truly sorry for getting everyone's hopes up and then delaying... again," said project lead Adam Engels via a recent statement. "We worked very hard to make December, but we are not yet ready. As a team, we take FULL responsibility for that. We have an internal deadline we are confident in, and we will be getting everyone more details as we get closer to that date.

"Thank you again to our community and Early Access supporters. The funding from Early Access has allowed us to hire many new talented developers, and has allowed older developers to put more time in the project. Simply put, Xen has proven to be an enormous undertaking, and while we are managing it to the best of our ability, it is proving to take longer than we estimated."

But while Xen release has been pushed back, there will nevertheless be an update next month. Focusing initially on improving stability and "enabling the new tech on the Earthbound section of the game", the final chapters will drop once everything's "fully stabilised". Tweaks include lens flare, texture blends, and improvements to the dynamic lighting—for the full breakdown, pop by the update on Steam.

You can pick up the Black Mesa mod now for $8, saving 60 percent off the full price. 

Half-Life 2 also continues to thrive, and Gunship Mark II's work-in-progress Half-Life 2: MMod is also gearing up for release.

Thanks, GameInformer.

Though the chances of us ever playing a new, official Half-Life game again are slim, Valve’s seminal series still has its hooks in us, as evidenced by the latest issue of PC Gamer. Ex-Valve employees are similarly plagued by visions of Gordon Freeman, the latest being Cayle George, whose free Half-Life 2 mod is now available on Steam. 

Half-Life: C.A.G.E.D. follows hot on the heels of the game jam inspired by the tweaked Episode 3 story synopsis from Marc Laidlaw, though it has nothing to do with Episode 3, instead being a prison escape mod, full of shooting and environmental puzzles. 

George’s worked with Valve, Monolith and Guerilla Games, and was a designer on Portal 2 and Team Fortress 2, as well as being a Half-Life modder before that. 

The short, single-player episode comes with developer commentary, along with a soundtrack from Lazerhawk. You can download it from Steam for free, but you will need a copy of Half-Life. 

Has it really been ten years since we last partnered with bespectacled scientist Gordon Freeman, and his daring sidekick Alyx Vance? It has! Which is why PCG UK 310 has that gorgeous luminous orange lambda scrawled over its cover. 

Inside The Half-Life Issue, Andy chats exclusively to the makers of third-party remake Black Mesa, and we celebrate Half-Life 2 with analysis, stories and jokes in our five-part retrospective. 

Elsewhere, you'll find the second half of our massive history of FPS games feature, and Steven gets to grips with the first MechWarrior campaign in 15 years. Previews this month include the new-to-PC Final Fantasy 15, Biomutant, Anno 1800 and more. And if that's not enough for you, this month's issue comes with free games: Warhammer 40K: Chaos Gate, and a Sudden Strike 4 demo. 

Issue 310 is on shelves now and available on all your digital devices from Google Play, the App Store and Zinio (they may be slow to update—look for that glowing Half-Life logo on the front). You can also order direct from My Favourite Magazines or purchase a subscription to save yourself some cash, receive monthly deliveries and enjoy our exclusive subscriber covers. This month's is an absolute belter:

This month:

• Andy gets exclusive access to Half-Life remake Black Mesa. 
• We celebrate Half-Life 2 in our five-part retrospective.
• Steven plays the first MechWarrior campaign in 15 years.
• Part two of our colossal history of FPS games feature.
• Tom recreates the PCG team for his review of XCOM 2's new expansion.
• XCOM 2: War of the Chosen, Rez Infinite, LawBreakers and more reviewed.
• Final Fantasy 15, Biomutant, Anno 1800 and more previewed.
• Our CPU cooler group test.
• And much more!

In the spirit of "why the hell not", a group of five modders is recreating Half-Life 2 in the Half-Life engine. There may be practical reasons for using this mod – maybe you don't own a copy of Half-Life 2 but you do own a copy of Half-Life – but these demakes are usually done just to see if they're possible. 

So far, so good: the team has already completed the game's first chapter, but they need help – especially from programmers and modelers. The mod's demo is currently available on ModDB, where you can also follow its progress.

"You might be aware that this has already been attempted already, but none of these have actually panned out," the description reads. "With Half-Life 2 Classic, we hope to communicate more with the community, so that even if we don't manage to recreate the whole game, we can still release a substantial part of it, which can be continued by someone else in the future."

Meanwhile, whether the mod will be a deliberately retro-styled outing, or whether they'll try to match Half-Life 2's fidelity, is yet to be seen. "We're still debating if we should stick close to Half-Life 2's graphics, or if we should downgrade them on purpose, and if so, how much. We may even make optional high-res models for the hd model pack, while keeping the base game's models low-res. But it depends on what most people want."

Check out the mod in action below. Cheers, Kotaku.

Half-Life got a new update today, which is significant for only one reason: the game is old. Old to the tune of nearly 20 years. So it's cool that Valve is still supporting it, despite Valve clearly not pulling its weight in other areas (releasing or even working on Half-Life Fricking 3).

The update addresses some small bugs the likes of which don't seem too gamebreaking, but since Valve probably wants to keep this game evergreen on Steam, it makes sense to address them. 

And yes, I've read the patch notes several times and there's no clear or obscure reference to any much-anticipated third instalment. Just take my word for it. Don't waste your precious time on this earth deconstructing the below published patch notes.

Here they are:

• Fixed crash when entering certain malformed strings into the game console. Thanks to Marshal Webb from BackConnect, Inc for reporting this.
• Fixed crash when loading a specially crafted malformed BSP file. Thanks to Grant Hernandez (@Digital_Cold) for reporting this.
• Fixed malformed SAV files allowing arbitrary files to be written into the game folder. Thanks to Vsevolod Saj for reporting this.
• Fixed a crash when quickly changing weapons that are consumable. Thanks to Sam Vanheer for reporting this.
• Fixed crash when setting custom decals

Half-Life: A Place in the West is a webcomic series set in Valve's esteemed Gordon Freeman-housing future world that's set between the events of the first and second games in the wake of the Seven Hour War. Created by Michael Pelletier, Ross Joseph Gardner, Heath Heil and Rachel Deering, issue one launch onto Steam towards the end of last year, with issue two landing in February this year. Now, issue three has a launch date: July 21. 

And to mark the announcement, Half-Life: A Place in the West Chapter 3 has a pretty nifty trailer. Observe:

Following the story of Albert Kempinski and his search for his kidnapped daughter, A Place in the West explores life and the trials and tribulations faced by the world's new cast of characters caught up in the dystopian city of New Franklin. The incoming third entry—named 'The Pit'—continues the exploits of Kempinski and his companion Leyla Poirier as they delve deeper into New Franklin's secrets. 

"The Pit is a culmination of everything we learned from the first two chapters," says writer and co-creator Gardner in a statement. "At a total of 30 pages, the condensed narrative is sleeker, much more focused, and really aims to bring the city to life."

Half-Life: A Place in the West in its entirety will run for a total of 13 issues—with chapter three due on July 21 for $1.99/£1.49. If you'd like to know about A Place in the West's origins, this article of Gardner's makes for pretty interesting reading. 

Tom Senior: Recently Game Informer disclosed the insights of a supposed Valve insider who insists that Half-Life 3 doesn’t exist in any meaningful form. RTS and FMV prototypes have apparently been toyed with, but the magical genre-shattering FPS sequel that the internet has been craving for nearly a decade isn’t real. Earlier this week Valve’s Gabe Newell did an Ask Me Anything on Reddit and suggested that Valve is still interested in revisiting the Half-Life universe, though “the number three must not be said.” Don’t hold your breath, basically.

Valve’s failure to release Half-Life 3 is not surprising because Valve has never announced Half-Life 3. The studio wanted to move from huge boxed releases to shorter development cycles and an episodic format, culminating with Half-Life 2: Episode Three. Episode Two ended on a savage cliffhanger, but that alone doesn’t fully explain why we want more Half-Life 10 years later. Half-Life 3 has taken on additional meaning. "HL3 confirmed!??" is a running gag, but a hopeful one. We want to believe.

For me Half-Life 3's absence feels like a symbol of Valve’s retreat from game development. I know this is ridiculous, because Valve is running Dota 2 and Counter-Strike: Global Offensive—two of the biggest games in the world. But I can’t enjoy Dota 2, because a) it demands massive time investment and b) in my experience as a new player in that community has been dreadful. I don't think I'm alone. I loved Left 4 Dead and Portal, and I had a great time with Alien Swarm, which Valve put out for free in 2010. I miss Valve’s humour and innovation, but if I’m honest I’m pining for Half-Life because Valve stopped making games for me. That’s a pretty petulant position, but there we are.

Samuel Roberts: I've always speculated that an unspoken reason behind Half-Life 3's continued non-existence is the burden to reinvent the first-person shooter again, just as Valve had done on two previous occasions. Is it enough for Valve to just make a super refined sequel, even if it doesn't have the impact of either of the previous Half-Life games? Well, yes—Portal 2 is exactly that model of follow-up. It wasn't a reinvention, it was a welcome extension of the first game's existing ideas. If the level and narrative design is strong enough, it doesn't feel like diminishing returns.

We need Half-Life 3 to complete the story of the series, but more than that, it's a better world for having more of Valve's single-player games in it.

Tom S: It is unfortunate that Half-Life 3 (or Half-Life 3: Episode Three) has become this mythical entity. We don't know what it looks like but it's everything we have ever dreamed a first-person game could be. That impossible expectation is good enough reason never to touch that series again. We've been banging on about it for so long that the stakes are crazy high now (and we are not going to stop, apparently).

Also shooters are in a good place right now. Last year brought us Doom, Titanfall 2, Battlefield 1’s Operations mode, Overwatch, and Rainbow Six Siege is ticking along nicely. If the rumours are true we could be looking at Destiny 2 on PC in the future. I’m hoping for another shooter from the Wolfenstein: The New Order team. I miss the jokes and the characters of the Half-Life universe, but the FPS hardly needs to be rescued.

Phil Savage: The thing with Portal 2, Sam, is that it did reinvent—just not the campaign. Through its level editor, It made Steam Workshop creation accessible to everyone, and not just people who are really good at making virtual hats. It worked! Portal 2's Workshop page contains over 557,000 items, and, while most of those will have never been played, it definitely extended the life of an otherwise unsurprising—albeit hilarious and with a better ending song—sequel.

I think that's what Gabe Newell meant when he said, in his recent AMA, that Valve's products are, "usually the result of an intersection of technology that we think has traction, a group of people who want to work on that, and one of the game properties that feels like a natural playground for that set of technology and design challenges." If Portal 2 was the Workshop, and Team Fortress 2 the ability to sell a fuckload of hats, what would Half-Life 3 bring to Valve's ecosystem? Maybe it's Source 2. Half-Life 2 was a great showcase for the original Source engine. Perhaps Half-Life 3 will be how Valve demonstrates the power of its successor.

Joe Donnelly: Sam and Tom's points about reinvention and the rude health of modern shooters are bang on the money, and while the FPS genre isn't in need of the same revolution brought by Half-Life 2 12 years ago, Half-Life 2 itself still one of the best first-person shooters on the market today. I revisited the Orange Box last year on a whim to see how Gordon Freeman's second outing fared against today's standards—a whim which had me rooting around Nova Prospekt a full week later, delighting in the how much of the game's wit, humour and expert design I'd forgotten since my first playthroughs.

We've missed this, and it was only by returning after such a long absence that I realised quite how much I miss this. To this end while seeing Half-Life 3—or HL2: Episode 3—powered by Source 2 or something newer would be lovely; I'd just as easy take a concluding chapter powered by the original 2004 engine. And, judging by some of the responses to Gabe Newell's mid-week AMA, I seem to be far from alone. This covers the want element, but do we need Half-Life 3? I reckon yes: evolution and nostalgia aside, denying players the chance to tie up Freeman's loose ends while treating themselves to another helping of what made number two so enjoyable is not only a disservice to players, but an injustice to videogames in general.

Tom S: Some fans have wondered if Valve could do a comic, or another similarly light-touch release, to tie up the end of the story. This seems like a good idea, and I enjoy Valve’s comics a lot.

I do wonder why Half-Life 2’s story still carries weight all this time later though. Half-Life opened with a B-movie premise—experiments gone wrong, the military sweeping in to cover things up. It gained a lot of detail with Half-Life 2, but it’s still pulp sci-fi to me. I mean, there’s a whole zombie movie pastiche in there.

Chris Thursten: Half-Life has always had revolutionary storytelling, but never a revolutionary story. The groundbreaking implementation of elaborate scripted sequences in the first game is why people remember it so vividly. The game never took control away from you: you were there, in Black Mesa, watching that otherwise-familiar B-movie premise explode to life around you.

Half-Life 2 took that further, and grounded a more sophisticated (but still familiar) story of near-future resistance in a believable dystopia. It has been widely imitated, and for good reason. It was a compellingly presented world populated by well-performed characters. Again, you felt like you were in a real place to an extent that you hadn't necessarily been in previous games.

In addition to advancing the FPS as a whole, then, Half-Life 3 would presumably need to advance our understanding of what a gameworld can be. This is where it gets much more complicated, I suspect. The advance of game engine technology has slowed. We're not blown away by see-saw physics any more. I wouldn't be surprised if Valve had experimented with VR with this in mind. Because what else could they do?

Aside from some staggering advance in graphics tech—that would still need to run on regular PCs—the best they could do is kidnap you, stick you in a helicopter, fly you to antarctica and force you to live the conclusion of Gordon's journey in real life. I mean, they could probably afford to do that. But should they? I've seen Westworld. The answer: probably not. (But please do it anyway, Gabe.)

Tom S: That’s settled, then. We do need Half-Life 3, and it needs to be an experiential future-tech extravaganza with deadly IRL headcrabs and reality-shattering see-saw puzzles. Get on it then, Valve.

Now that our game of the year awards are out of the way, we can get to the serious stuff: ventilation shafts. They’re a pillar of modern game design, shunting players from one level to the next, telling spy wannabes that a square aluminum tunnel is all espionage requires, and giving the hunted a temporary haven from their mouth-breathing pursuers. The most iconic protagonists in PC gaming depend on inexplicably designed air convection systems to save the world time and time again.I'm going to revisit a few of the most recognizable vents from PC gaming history and evaluate them based on rules I’m making up as I go. One lucky duct will win the coveted PC Gamer Gust of Approval for best vent.

Deus Ex: Human Revolution 

Gif sourceThe original Deus Ex invented the concept of ventilation shafts, and as a result is exempt from competing. Unfortunately, further iterations of ventilation shafts from the new handlers at Square Enix didn’t do much to blend them into the environments or make them feel like genuine air ducts. Instead, they serve as well-lit (somehow), long graves where you hide your dead. How many bodies can you fit in an impossible space? Deus Ex: Human Revolution steps beyond the veil.Even worse, the vents aren’t in compliance with the ASHRAE standards for acceptable air quality. According to section 5.1.1 of the guidelines, “Where interior spaces without direct openings to the outdoors are ventilated through adjoining rooms, the opening between rooms shall be permanently unobstructed.” These dead bodies are breaking the law.

Deus Ex: Mankind Divided

They are deeper, wider, and more Jensen-sized. Seriously, they’re massive. And they’re always hiding behind vending machines and small crates, leading directly to and fro with plenty of slats along the way just in case you need to see where all the guards are hanging. Subtlety doesn’t circulate in the near future, I suppose. Air isn’t getting through those suckers in a sensible way. It’s a fact: these vents blow.

Watch Dogs 2 

Pitiful, but so pitiful, I can’t help but love it. There’s been no effort made to hide that this vent in a multi-billion dollar tech company building was built specifically for drone passage. (Just a heads up, this is how you get raccoons.) Watch Dogs 2 makes little effort to mask its videogame vents as anything but transparent chunks of level design. It’s one of the bigger problems I had with the game, that it promises options for infiltration, but vent layouts are so arbitrary and assured to lead directly between points of interest that they start to feel like a big billboard, stating ‘Sneak here!’

Metal Gear Solid 5: Ground Zeroes 

Gif sourceOK, so it’s more of a drainage system, but it might also push some air around. Note the more rectangular design gives the impression that they’re a tighter fit than most videogame vents, which makes for a more immersive ventilation shaft experience. Were I in a crime film, I’d consider using such a discreet, small passage as a good place to hide the murder weapon. Were I in a videogame, I’d glitch through the floor and fire my weapon with reckless abandon. In conclusion, I love the compress of MGS5’s passages, but otherwise, they rarely make sense. Often, they’ll just lead from a hole outside a building in a direct line inside. You’re going to get raccoons, damnit.

Half-Life

So very, very dark. Like a damn vent should be! If I’m supposed to suspend my disbelief that these big metallic crawlspaces are mean for air circulation and not hiding headcrabs, I want them to at least distract me with tension. The vents are otherwise featureless, vanilla shafts. Four walls, grey, nothing particularly special about them. At least they acknowledge you’re going to get critters with such impractical vents, even if they’re interdimensional face suckers.

Half-Life 2

Talk about sequelitis! No innovation. Expect more flat, boxy aluminum textures, more headcrabs popping out to say hello, and most grievous, of course, are the impractical air convection layouts. The thought makes me shiver, not because it’s abhorrent, but because damn, it’s cold in here, Gordon!

Batman: Arkham Series

Gif source

Gotham’s vents are comically large. Bruce Wayne isn’t a small man, especially with an extra few inches thanks to bat ears. And crouching isn’t easy in all that armor—it’s going to bunch up, Bruce. I’m sorry but your tummy is getting pinched beneath those plates. God forbid you drop a quarter. To accommodate all that batmass, the vents essentially serve as a venue for badguy shadow puppets and an echochamber for the Joker’s prolonged loudspeaker monologues. They’re a nice place to hide in if you’ve been spotted, but their design won’t win any awards from us. Often they serve as a comically short passage between two rooms, ensuring the only air they’re circulating is Wayne’s big ego.

WINNER — Alien: Isolation

We praised Alien's production design during release, and Creative Assembly's extraordinary attention to environment detail extends to the design of its vents. The aperture entrance to each vent is accompanied by a slick cylindrical animation and shrill soundbite that sounds like a sword being pulled from its sheath. Foreboding, a bit, considering there’s probably a hungry alien in there.Isolation’s detailed lighting and shadows give the impression that Sevastopol is a hulking, intricate tangle of retro-futurist industrial design. As you crawl through every vent and maintenance shaft, you’ll get small glimpses into the guts of the station, a smoky mess of pipes and dim lights and scattered tools. The result is a space station that feels so vast and cobbled together that its tiny passages and maintenance systems feel plausible. Vents that don’t make sense, make sense on Sevastopol.To the team at Creative Assembly, you’ve creatively assembled good passages behind the walls for players to bonk around in that don’t feel like a mad maintenance man’s pet project. Your congratulatory PC Gamer Gust of Approval should make it your way soon.

It's been over 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. The most recent information comes from a 2017 Reddit AMA with Gabe Newell and some major revelations from an interview with 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 screenshot began circulating. 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 

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, " ." 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.

April 2012 – P-powered

Proving that simple is sometimes best, an April Fool joker caused millions of fans to momentarily go nuts when he posted a Half-Life 3: Now Available image at store.steamppowered.com. (The URL now leads to a potential phishing site, so we've disabled it.) Some legitimate news sites fell for it, so excited were they by the prospect of Half-Life 3 being honest-to-God real that they failed to notice the extra "p" in the URL. The site remains up to this very day, although it's now tagged with a notice that it is in fact an April Fool's joke.

April 2012 - Ricochet, too?

Valve honcho Gabe Newell confused everyone when he discussed the development of Episode 3 in the context of Ricochet 2, the hypothetical sequel to the Valve-developed battle frisbee game.

"We'd like to be super-transparent about the future of Ricochet 2," he said, "but the problem is that the twists and turns that we're going through would probably drive people more crazy than being silent about it until we can be very crisp about what's happening." I can't say that I'm really with you on that one, Gabe, at least not here in the year 2016. The good news, Newell added, is that "everyone who's working on Ricochet 2 continues to work on Ricochet 2."

And so now we sometimes refer to Half-Life 3 as Ricochet 2, and may forever.

June 2012 - Concept art slips out

This leak came to us through the bad luck of artist Andrea Wicklund, whose Picasa portfolio ended up spilling concept art all over the net. Images included Alyx in various get-ups, a crashed helicopter in the Arctic, and pictures of the alien world Xen. Interestingly, while the art was dated from 2008, it didn't slip out until mid-2012.

August 2012 – No responsibility is taken

The 2012 edition of Gamescom promised to be an exciting one: Games scheduled for exhibit that year included Dragon Age 3 and Half-Life 3! Before we could line up for plane tickets to Germany, though, a correction was issued. Eurogamer asked three separate times why the titles had been listed, but Gamescom would only say that it was "a mistake."

June 2013 – Jira leak, stage one 

Data from Valve's project tracking tool (Jira) leaked to the public, revealing that 42 people are attached to a Half-Life 3 mailing list. Obviously, there was no way to verify that the leak was real, and even if it was, determining the age or status of the mailing list in question was impossible too. Maybe 42 people were working on Half-Life 3, or maybe 42 people are just too damn lazy to unsubscribe from the list. (I don't judge. I have two Felix the Fish plushies, because it was easier to let Big Fish Games sock my credit card for 7 bucks a month than to figure out how to make it stop.)

June 2013 – It was just a joke, we swear

A motley crew of yuksters manages to "accidentally" convince people that Half-Life 3 is in development in a segregated section of Valve's studios, and that a reveal of the project was finally imminent in the pages of their own magazine, no less! Which gang of comedy doofuses cooked this one up, you wonder? I cannot tell a lie: It was us (but it was meant to be an obvious joke, not a hoax).

August 2013 - The pen is mightier

A Steam dev posted an announcement of the beginning of a Half-Life 3 internal beta on the community announcements page. Real developer, real community post but fake announcement, as a close look at the list of updates makes clear. The dev in question quickly copped to it, saying he didn't "expect it to show up everywhere." Because when has that ever happened before, right?

August 2013 – Mr. Overwatch causes a stir 

John Patrick Lowrie, voice of Odessa Cubbage and husband of Combine Overwatch and GlaDOS voice actor Ellen McLain, caused a stir when he explained that Half-Life 3 wasn't moving forward because of challenges with motion capture which of course implied that he had some insight into the situation. He even said that overcoming mo-cap limitations was "one of the things they're working on," meaning that it was gasp! being worked on. Progress! Except, four days later he took it all back, saying that he doesn't know nothin' about nothin', and nobody can prove otherwise.

September 2013 – Jira, part deux 

Jira leaks again! This time there was a new "Half-Life 3 Core" group listed, and the number of people on the project had grown, too. That's practically an official announcement, right?

October 2013 – European trademark 

A trademark filing for Half-Life 3, owned by Valve, appeared in Europe. Trademark filings are a great way to get an early heads-up on new game projects: Deus Ex: Mankind Divided and Gwent are two high-profile examples of games that came to light first as a result of a trademark filing. Half-Life 3 trademarked? Half-Life 3 confirmed!

October 2013, one week later – European disappointment 

Half-Life 3 de-confirmed. Fake filing. Why does this keep happening?

May 2014 – Minh Le has seen things 

Counter-Strike mastermind Minh Le told goRGNtv that he'd seen Half-Life 3 concept art, and the game is in fact being worked on! Sort of, anyway. More precisely, he said he saw something "that looked kinda like in the Half-Life universe," although he seemed surprised that anyone would be interested in such a thing. It also wasn't clear when he'd seen the material in question, since he'd left Valve several years prior to the interview. He was also clearly far more interested in Left 4 Dead 3 than anything to do with Half-Life. Thanks for nothing, Minh.

October 2014 – A bad idea 

The "We Want Half-Life 3" Indiegogo campaign wasn't a Half-Life 3 hoax or broken promise, just a monumentally bad idea. Basically, a couple of advertising types decided to crowdfund a harassment campaign to let Valve know that people really want them to make Half-Life 3. You know, in case that wasn't clear. They asked for $150,000 for their campaign (which, in their defense, they later clarified was meant to be a one-day lark rather than concerted stalking); they closed with a little shy of $1600.

June 2015 – Another fake site 

Sweet Aunt Petunia, a Half-Life 3 logo actually appeared on the Valve.Software website. Unfortunately, that site is not actually related to Valve Software, but for a few delicious hours (or minutes, depending on when you heard about it and how innately suspicious you are of such things) we could let ourselves believe that the light was finally shining. The site is still up and the HL3 logo still there, but the fine print makes it clear that it is "just a joke site." Half-Life 3 hoaxes are no joking matter, Timmy.

October 2015 – Dota 2 discovery 

A file named hl3.txt was found in a Dota 2 update, containing references to "Combine Pulse Ceiling Turret" and "NPCs that are in the same squad (i.e. have matching squad names) will share information about enemies, and will take turns attacking and covering each other." That's straight out of a Combine soldier AI script, but what's with the hl3 filename? Valve maintained its usual stony silence, but I think it's worth noting that a year later, Gordon Freeman still hasn't appeared in Dota 2. That has to mean something.

Jan 2016 – Confusion on Reddit 

Drama in r/HalfLife, billed as "possibly the first legitimate Half-Life 3 leak." What's interesting about this one is that as far as I can tell, nobody is entirely, 100 percent certain that it was a hoax. The information provided was deep, detailed, and not at all flashy in the way of most other gag teases, and its veracity was backed, in ways he couldn't or wouldn't make clear, by the forum mod. Eventually, the whole thing just fizzled out, without the usual "lol suckers" flourish at the end, which could be seen as further "proof" that the leak was real. But probably not.

 February 2016 – Virtual teasing 

The innocuous-sounding SteamVR Performance Test software, an app intended to determine whether or not your rig is up to the strains of virtual reality, is found to contain some Half-Life secrets in its code, including a high-quality 3D model of Dog, the super-strong, ball-fetching robot from Half-Life 2. Half-Life 3: The VR Experience, perhaps? Not likely: The software contained material from other Valve games too, including Left 4 Dead and Dota 2, and writer Chet Faliszek was quite clear on the point when asked about it last year. (He said "No.")

August 2016 – Gamescomedy 

Right there, large as life and side-by-side with Titanfall 2, was a poster proclaiming, plainly and boldly, Half-Life 3! And some fine print underneath, which might have been missed at first because the poster said Half-Life 3! Except it was actually Half-Life: 3, as in, "Half-Life: 3 editors who played it back then." It's not so much a hoax as a lazy gag, but we all spasmed reflexively and so it gets the credit.

And that brings us to today, at least until the next joke, leak, hoax, apparent ARG, or off-hand comment. We give it at least 24 hours before that happens.

January 2017 – We never promised you a rose, Gordon 

"There is no such thing as Half-Life 3," an anonymous Valve developer tells Game Informer. "Valve has never announced a Half-Life 3. The closest they’ve come is after Half-Life 2, they said there would be three episodes. We only got two of those. That is arguably an unfulfilled promise. Anything else that we might think about as a full game or sequel has never been promised."

In other words, who ever said you were getting Half-Life 3 in the first place?

January 2017 – Ask no questions, hear no lies 

Valve top banana Gabe Newell takes part in an AMA in which he acknowledges the existence of questions about Half-Life 3. When asked about the status of HL3 or Half-Life 2 Episode 3, he says, "The number 3 must not be said." And all those rumors that just won't go away? "I personally believe all unidentified anonymous sources on the internet."

February 2017 – Kids will be kids 

Newell lays the blame for some of the persistence of Half-Life 3 rumors at the feet of Valve employees, who he says get a kick out of messing with people—although he's above such things himself, of course. "Some of the more childish members of our company have worn Half-Life 3 t-shirts to GDC," he says (via VentureBeat). The appearance of an HL3 icon in a photo of a monitor at Valve was, Newell adds, was "news to us."

(Click the upper right corner to enlarge the image above, and squint at the icon above the recycle bin on the monitor.)

July 2017 – "I have no interest in going back." 

Half-Life and Half-Life 2 writer Marc Laidlaw, who left Valve in January, tells Arcade Attack that he has no idea if Half-Life 3 will ever see the light of day, and doesn't much care anyway. "I had ideas for Episode 3. They were all supposed to take the series to a point where I could step away from it and leave it to the next generation," he said.

And even if it is released someday, he doesn't think it will actually bring with it any sort of proper resolution: "My intention was that Ep3 would simply tie up the plot threads that were particular to HL2. But it would still end like HL1 and HL2, with Gordon in an indeterminate space, on hold, waiting for the next game to begin. So one cliffhanger after another."

August 2017 – Gertrude Fremont gets involved 

This one also comes courtesy of Mr. Laidlaw, who shares what is apparently a twisted-up synopsis of Half-Life 3 on his blog. Eli Vance is confirmed dead, Dr. Mossman tracks down the Borealis, Gordon and Alyx travel to Antarctica to handle the situation, and of course the plan falls completely apart before it even begins. What's especially interesting about the story is that it's basically "gender-swapped fan fiction," as we called it: Male characters are female and vice-versa, names are changed up slightly, but remain close enough to the originals to be recognizable by fans.

Assuming Laidlaw didn't make the whole thing up to mess with people (as Valve employees like to do, remember), Half-Life 3 would end with Alyx Vance murdering Dr. Mossman, after which the G-Man takes her away in place of Gordon; Gordon escapes his seeming inevitable doom with the help of the Vortigaunts, and by all appearances his role in the series is over, as Laidlaw had intended. How much validity there is to Laidlaw's tale is impossible to judge, but it does have one thing going for it: You can play (kinda, sorta) play it. 

November 2019 – Half-Life the third 

It isn't exactly Half-Life 3, but Valve has just announced a prequel to the series called Half-Life: Alyx coming in March 2020. You'll be able to play it with any PC-based VR headset when it releases. Although it doesn't actually have a "3" in the title, this is very much a third Half-Life game, clocking in at a similar playtime to Half-Life 2. It is reportedly the biggest team of developers that Valve has ever had working on a single game. Check the link above for all the other details on the prequel.

In a followup interview, The Verge asked designer David Speyrer if this was a full return to Half-Life and if we could expect more games in the series now that Valve has finally brought it out of stasis. "It’s probably no surprise that many people at Valve have been wanting to get back to the Half-Life universe for a long time," Speyrer said, "and this experience has only reinforced that." He elaborates, explaining that Valve has explored new ways to tell stories in the Half-Life world and new gameplay experiences it can create for players.

"Of course, we’ll have to wait and see how people react to Half-Life: Alyx once it’s out, but we’d love to continue pushing forward," Speyrer said.

In the original Half-Life, as Gordon Freeman makes his way to work on that fateful day in the Black Mesa Research Facility, you find a break room. A scientist sits at a table drinking from a coffee cup, and another paces the room. Then you see it. A microwave with a container of some unidentifiable food within, begging to be interacted with. There s no button prompt on the screen telling you to do so, but you just know that if you press the use key next to it something will happen. Something incredible. Something messy.

So you press it, and it beeps. Nothing. You press it again, and this time it beeps at a slightly higher pitch. A clue that you should keep pulling this thread, even though it looks like nothing is going to happen. So you hammer the use key until, suddenly, the dish explodes. The microwave is covered in yellow gunk and the pacing scientist rushes over. My God! he exclaims. What are you doing? He sadly observes the mess you ve made, but Freeman says nothing. You walk away, no apology, no remorse. Classic Gordon.

Valve knows what we re like. If we see something, we re going to try and interact with it. Doubly so if it looks like it was never meant to be interacted with, or if it s out of reach. And it s great that games like Half-Life reward this very human curiosity. There are few things in videogames more satisfying than hitting the use key next to some prop, and something happening in response. When it doesn t, it s always a disappointment. It makes the game world feel somehow more lifeless, more artificial. Like you re in some kind of cardboard film set rather than a real place. If I ever move near a hand dryer in a videogame bathroom and it doesn t roar into life, my immersion shatters into a thousand twinkling pieces.

I feel for the developers, though. They have to dedicate time and resources to modelling, texturing, animating, and creating sound effects for the most mundane objects. But it s work that s always appreciated. In the latest Deus Ex game, Mankind Divided, Adam Jensen s apartment is a funhouse of stuff to switch on and mess with, from the flushing toilet to the washer and dryer that start rumbling when you power them on. Eidos Montreal didn t have to do any of this stuff, but it makes all the difference that they did.

Flushing toilets, incidentally, have become the go-to test of a game s interactivity. There are even websites cataloguing all the games that feature them. Because it s the internet, and of course there are. Be honest: the first time you encounter a toilet in a game, you try to flush it. You probably even do it without thinking, instinctively hitting the use button when you re near one. And if nothing happens, and you don t hear that familiar rush of water, you wonder if the game s even worth your precious time.

In the years since Half-Life was released, the exploding microwave is still perhaps the best example of this kind of interaction. But there are others. Human Head s 2006 shooter Prey opens in a brilliantly interactive bar, boasting a TV with channels you can switch, playable gambling and arcade machines, and a jukebox with tracks by Judas Priest, Blue Oyster Cult and other classic rock groups. It s completely unnecessary, and doesn t reflect the rest of the game, but it speaks volumes that people still mention it now. In fact, I can t really remember anything about Prey except the bar scene.

Some games even make a feature out of switching things on. In Hitman, turning a radio on or getting a sink to overflow is a frequently invaluable way to lure a guard away from his post. But often you need a certain item to turn said thing on, such as a wrench or a screwdriver. IO Interactive has cleverly looked at how people love interacting with objects in games and designed a system around it.

Environment artists are doing incredible work these days, giving you increasingly detailed, atmospheric worlds to exist in. But no matter how complex the geometry is, how high-res the textures are, and how gorgeous the skybox is, it won t matter if we approach that toilet, press the use key, and it doesn t flush. As games get more expensive to develop and assets get more time consuming to make, I hope developers never forget that, above all, people just love turning things on. The toilet must always flush.
