Like Doc Brown, I once hit my head and saw the future. I didn't come round in the bathroom having the idea for the Flux Capacitor, but I did bonk my noggin pretty hard in the office games room and sit back, dazed but delighted with what had just happened.
I was playing the Budget Cuts demo on Valve's room-scale VR. Budget Cuts is a game about infiltrating an office that's patrolled with deadly robots. Because of the room-scale VR, you're really there: your actual body is your in-game body. This means that the robots are the same size as you - which is terrifying - and it also means that when you have to duck your head through a missing panel in the floor to look into the room below, you really have to do it. Except that while the game floor might be missing a panel, the real floor isn't. Bonk. I did it. Chris Bratt, who had also played the demo, had done it. A day later, so moved by what I'd played I brought in a friend to try it out. They did it too. We all hit our heads and we all saw the future.
More than just the future of video games, I really felt like I had seen the future of one series in particular. I still think this. I still think that Budget Cuts is essentially the closest I've ever gotten to playing Half-Life 3. It's not set in the Half-Life universe, although its mixture of horrific technology and the banal and bureaucratic is not a million miles away. It wasn't made by a Valve team, although I gather the people who made it did end up working on the final game at Valve as incubees. Instead, it channels that magical thing that Half-Life has always done.

UPDATE 19/11/19: After 12 long years of waiting, and enough "3"-based memes to fill an entire internet, it's finally official - there's a new Half-Life game on the way. As previously rumoured, it's called Half-Life: Alyx and Valve describes it as the company's "flagship VR game".
Half-Life: Alyx will be given the full reveal treatment this Thursday, 21st November, at 6pm in the UK/10am Pacific Time. Valve hasn't said where yet, but it seems reasonable to assume it'll pop up on Twitter and will be plastered all over the front page of Steam.
ORIGINAL STORY 18/11/19: A formal announcement of Valve's long-in-development Half-Life VR project looks finally on the horizon.

Valve has fixed NPCs not blinking in Half-Life 2, its 15-year-old shooter that may never see a sequel.
That's not all. Valve has also fixed missing sounds on Combine soldiers, fixed a hitch when saving games, and fixed SteamVR running when entering the settings menu.
The update is for Half-Life 2, Half-Life 2: Episode 1, Half-Life 2: Episode 2, Half-Life 2: Lost Coast, and Half-Life: Source. So, all the Half-Life 2s!

Valve, alongside its business partner in China, Perfect World, has given us an update on the progress of Steam China today, after both companies had been silent on the topic for over a year.
Eurogamer attended the brief presentation, given by Perfect World CEO Dr. Robert H. Xiao in Shanghai, where a small number of local and international press were told the companies were "one more step closer" to launching Steam China, which will be separate from the international version of Steam. A handful of launch games were revealed, including Dota 2 and Dota Underlords. There were no actual launch dates or broader windows mentioned for Steam China itself, mind, nor a look at how that storefront may shape up or any details on its features, barring the fact it'll support VR, multiplayer games, interesting games with "innovative, creative ideas," and "single-player games with abundant storylines". As far as we could tell, none of the non-Chinese launch games had official approval just yet, either.
In Xiao's words, "the Steam China project is undergoing solidly and smoothly" - but what is it, exactly? As it stands, Steam is actually widely available for Chinese players already. As of right now we've tested and confirmed it's possible to buy, download and play games through the Steam store in China as usual, with no issues - and no need for a VPN. Community features, such as discussion forums, are unavailable, but otherwise the platform as it stands still acts as a huge loophole in the Chinese government's strict regulation of games. Where it might take many months of admin and applications for a game to get through the approval process - if it gets through at all - or many revisions to a game's content to ensure it meets the various Chinese standards, that same game can already be bought and played in China, unfiltered, unregistered and unchanged, on regular old Steam.

UPDATE 7.58pm: As the shadow of hatmageddon continues to loom over Team Fortress 2's trading economy, Valve has taken early steps to prevent players from securing more rare head adornments using the game's current loot box glitch.
In a bid to stop further Unusuals from flooding the market, Valve has now (as detailed by TF2 reddit mod wickedplayer494) disabled the display of Team Fortress 2 inventories on the Steam Community, preventing trades and listings on the Community Market. Player items can, however, still be used in-game.
Valve has yet to issue an official statement on the glitch - or indeed what, if anything, it plans to do to restore order to the TF2 trading economy - but at least the community will be impeccably attired while the whole thing sinks into the mud.

Viktor Antonov hasn't built a world like this before.
The games you know him for are bounded and largely linear. Every tiny detail has been touched by a human hand in Half-Life 2's City 17 or Dishonored's Dunwall, striking virtual places which Antonov has helped colour with particular social histories and inscribed with visual techniques that quietly guide the player to the next checkpoint. That's also true of other games that he's been involved with over the past few years, such as Wolfenstein: The New Order, Prey and Doom, on which Antonov acted as visual design director.
But Project C, as the game is currently codenamed, is very different. "It's one of the most ambitious projects I've worked on and, I have to admit, a fairly difficult one for me," he says.

There is a saying in architecture that no building is unbuildable, only unbuilt. Structures may be impossible in the here and now, but have the potential to exist given enough time or technological development: a futuristic cityscape, a spacefaring megastructure, the ruins of an alien civilisation. However, there are also buildings that defy the physical laws of space. It is not an issue that they could not exist, but that they should not. Their forms bend and warp in unthinkable ways; dream-like structures that push spatial logic to its breaking point.
The Tomb of Porsena is a legendary monument built to house the body of an Etruscan king. 400 years after its construction, the Roman scholar Varro gave a detailed description of the ancient structure. A giant stone base rose 50 feet high, beneath it lay an "inextricable labyrinth", and atop it sat five pyramids. Above this was a brass sphere, four more pyramids, a platform and then a final five pyramids. The image painted by Varro, one of shapes stacked upon shapes, seems like a wild exaggeration. Despite this, Varro's fanciful description sparked the imaginations of countless architects over the centuries. The tomb was an enigma, and yet the difficulty in conceptualising it, and the vision behind it, was fascinating. On paper artists were free to realise its potential. If paper liberated minds, the screen can surely open up further possibilities. There's no shortage of visionary structures within the virtual spaces of video games. These are strange buildings that ask us to imagine worlds radically different to our own.
Whilst many impossible formulations are orientated towards the future, there are also plenty from the past. The castle in Ico is one example of this. During the Renaissance, Europe was obsessed, not with future utopias, but with ancient Greece and Rome. While the box art of Ico is famously inspired by Giorgio de Chirico, the long shadows and sun-bleached stone walls only make-up a portion of the game's mood. It is the etchings of Giovanni Piranesi that best capture what it's like to explore the castle's winding stairs and bridges. Piranesi's imaginary Roman reconstructions were absurdly big - so colossal you could get lost in just the foundations. In a similar way, Ico's castle is impossibly large, the camera zooming out in order to overwhelm you and build up the unfathomable mystery of its origin and purpose.

CS:GO went three to play and got a battle royale mode last week - but the surprises didn't end there, as players discovered a cryptic message which some speculated was an ARG to tease Portal 3. Despite the best efforts of CS:GO sleuths, however, Valve has since confirmed this is actually just an Easter egg - although it's still a pretty neat discovery.
The fun and games began when YouTube user snaileny posted a video of a "strange broadcast" they'd found on the new battle royale map dz_blacksite. According to snaileny, to hear this you have to stand in Room 3 for over two minutes before the (slightly creepy) message begins to play.
Players figured out the beginning of the list is in the NATO phonetic alphabet, and translates to PGPW50 SMS757 - the first half of which refers to the PGP word list (an extended biometric word list designed to prevent wiretapping). The transmission, when converted into the PGP word list, gives you 50 pairs of numbers and letters. Reddit user GetSomeGyros then figured out that the "SMS7" part of the message, meanwhile, refers to GSM 7-bit encoding: and when you put PGP pairings into this, you get the following message:

UPDATE 26/10/18: All good things must come to an end, but it seems TF2008's end came particularly quickly, as the mod's newly-approved Steam page has now been removed.
According to an email screenshot shared on the mod's Discord server, it appears Valve has U-turned on its decision to launch the mod on Steam. The reason cited is the modder did not sufficiently prove they were creating "a mod of TF2 and not just repurposing leaked code". The email did not rule out the possibility of the mod returning once the modder had sufficiently demonstrated the code used was not leaked.
It seems modder XYK had other ideas, however, as the TF2008 Discord server has now been deleted. Well, sort of - it's called "Burger" and all the previous comments have been replaced with pictures of food. XYK left the server with a deeply unpleasant parting comment, while footage saved on YouTube shows the mod community go into meltdown following the news the server was to be deleted.

Despite being released over 10 years ago, Team Fortress 2 still boasts one of the biggest player bases on Steam. Today, the number of players peaked at 54,350 - placing the game at seventh on Steam's leaderboard of most-played games. And behind the player count, there is still a significant esports community organised by a series of leagues unaffiliated with Valve. TF2 players have run a small but passionate competitive community for several years.
Over the past few weeks, however, a darker side of the community has emerged. Several competitive players and community members have reported experiencing a culture of harassment and toxicity. The community members took to social media to reveal harrowing personal stories of racism, sexism, transphobia and sexual abuse. To make matters worse, some professional TF2 players have responded to the social media posts with insults and derogatory terms aimed at the victims. Since the reports of toxicity in the competitive scene emerged, other players have come forward with their own stories, and it seems the problem is pervasive. The affected branches of the TF2 community include the TF2 workshop, Steam comments and public matches in the game itself.
Although many of the competitive leagues have responded with statements, bans and policy changes, some have remained silent on the issue. Players have also reported the toxicity goes beyond the competitive sphere to almost all parts of the Team Fortress 2 community - so the question is, should Valve do more to discourage it?
