When Half Life: Episode 3 concept art surfaced on the facebook page of fansite ValveTime yesterday we were sceptical, but it's increasingly appearing that they really could be from the long awaited sequel.

Most of the artwork depicts a snowy wilderness with characters clad in winter clothing. This tallies with location the Borealis, the Aperture science ship that was revealed to be stranded in the Arctic in Episode Two. More intriguingly several of the stranger pieces of artwork contain the word 'Xen' in the file names, the Alien world visited in the original Half Life's final act.

OXM have been on top of the story and note that moderators on the Steam forums are claiming the pictures are genuine. Meanwhile fansite Lambda Generation traced the images back to a (since deleted) Picasa gallery belonging to Valve artist Andrea Wicklund.

Now here's the bad news. Although they were only recently discovered these images were all uploaded to Picasa in March 2008, only a few months after the release of Episode Two. This means that even if they are genuine, they aren't necessarily indicative of the direction Valve are taking now, four years later.

You can see the full gallery of images over at Valve Time.

It's alive! A bunch of new screenshots have gone online for Black Mesa: Source. In case you'd missed it, or forgotten it in these years of silence, BM:S is a fan project that aims to recreate the entirety of Half-Life 1 in the Half-Life 2 Source engine. The devs promised to releaser more details if their Facebook page hit 20,000 likes. It did, and they have. So without further ado, here are eight new screenshots for Black Mesa: Source.

It's been quiet for so long, I never thought I'd get to write that. It's worth keeping an eye on the Black Mesa site for more updates soon. "This is just the beginning. We have more in store for you in the near future! Hold on to your lab coats!" say the team on Facebook.

Oh happy day. As someone who resents leaving the safety of his Ubuntu desktop every time I want to play a game or do some benchmarking, today's headline from Phoronix.com is frankly the news I've been waiting for for years.

Valve has been recruiting for at least one Linux specialist to help port Windows games with this job ad since January. But it looks like they're getting very serious, and keen to push on with the project. Phoronix' Michael Larabel has received an email from Gabe himself asking for help head hunting.

The email to Larabel, which has been confirmed as genuine, reads:

We are running into a bunch of performance issues in Linux drivers (e.g. 50 millisecond draw calls because thedriver is compiling a shader). 

We'd like to hire someone to work on these performance issues. If you know of anyone we should be talking to, I'd appreciate getting connected with them.

This isn't overly surprising, but it is reassuring. With the rapid rise of Android as a gaming platform, and recent changes to the Linux kernel which integrate Android code, there's every reason for developers to start treating open source more seriously. The Humble Indie Bundle has proven that there's a market for Linux gaming too, as grateful Tuxheads spending more than Mac users.

It could well be that they're looking for someone purely for internal testing and research with no firm plans to bring Steam or games to Linux yet. But neither the ad or the email seem particularly speculative.

I'd never be as foolish as to predict the rise of the Linux desktop, but the operating system is pervasive in other ways that might become a more common desktop alternative.

We've seen some impressive fan-made Portal guns in the past, but they've been rare, costly one-off projects. Valve are giving us the chance to get hold of our own Aperture Science Handheld Portal Devices without having to burn ourselves horribly putting together an injection mould. Joystiq mention that, at Valve's request, toy manufacturers, NECA have put together a life-sized Portal gun. It'll hit the shops this summer with a $130 price tag attached.

There will be lights and those lights will change colour, but will it make the "pwung" noise? There's only one way to find out, and that's to buy at least five. Perhaps ten. Maybe more. More. MORE.

NECA will also be releasing a line of Left 4 Dead, Team Fortress 2 and Half-Life action figures, a few of which were shown off at the NYC Toy Fair. The Team Fortress 2 wiki has a snap of the new figures, you'll find that below along with a few shots of that Portal gun. Baggsy the Heavy.

This Saturday the 28,000 members of this Steam group are planning to play Half-Life 2 together. It's single player, of course, but there's nothing stopping fans from getting together to stroke their chins and nod slowly in mass mutual appreciation for one of the best shooters ever made.

The group hopes that the massive play session will shoot Half-Life 2 up the Steam most-played list and let Valve know how many people are still waiting for Half-Life 2: Episode 3. Valve certainly know this already, and probably receive dozens of emails every day asking "WHERE AM HL3?" but the group hopes to deliver the message in a more appreciative way.

"Instead of focusing efforts in a negative and disrespectful way, we have decided to gain Valve's attention by delivering a basic message: Your oldest and longest running fanbase would like better communication," they say on the Steam group page.

Even if you're not interested in sending Valve a message, any excuse is a good excuse to dip into Half Life 2 again, so why not join in? You can join the Call for Communication to add your weight to their message, or you can boot up and play a little for old times' sake and spend some time with Eli, Alyx and the crew. It's set to kick off at 7PM GMT / 11AM PST this Saturday. Thanks to Brett and Smash for the heads up.

Even though Lego Lord of the Rings has been announced, we reckon they’re fast running out of franchises to render in acrylonitrile butadiene styrene. Lego James Bond is the one we always mention when we see the Traveller’s Tales guys, but so far we’ve had no luck convincing them that squashing a plastic version of Sean Bean with a giant satellite array would be a very good thing.

Flickr user Catsy has completely inspired us to believe that a Lego version of Half-Life would be the way for Lego to go. As Kotaku reported, he/she has created a Lego version of Gordon Freeman using stock Lego bits and bobs, equipped with a customised Overwatch Standard Issue Pulse Rifle made from a Lego tommy gun.

As Catsy notes, Freeman needs a little more smoothing and painting. But between his/her and Orrange Stahl’s attempts at Lego Half-Life, we think there’s more than enough to convince the Danish toy giants to create Lego versions of Freeman, Alyx Vance, The G-Man et al. Who knows, maybe they could even make a game of it.

It's just a man in a T-shirt of course, but there's a Half-Life 3 logo on the front of it and a Valve employee inside it.

Art director and executive producer at UberEnt (the team behind Super Monday Night Combat) posted the photo above on Twitter with the message "All I'm saying is I saw this at a local game developer event worn by a Valve employee," sensibly attaching a #ValveTrolling hashtag. He couldn't get any more info out of Valve's man but he confirms that "I did try to smother my face in his chest on the HL3 logo." This did not help.

A long time ago, when dinosaurs roamed the earth, Valve announced that they'd release three follow up episodes for Half-Life 2, allowing them to put out shorter stories at a faster clip. The episodes so far have taken longer and longer to develop, and Episode 2 ended up being longer than most modern shooter campaigns. Years on from Episode 2's release, it would make sense for the next game to ditch the episode format and become Half Life 3. Recently, the Cambridge Student asked Gabe Newell whether he considers releasing Half-Life 2 sequels in an episodic form a mistake. "Not yet," he said.

Valve have repeatedly said that they're still committed to the Half Life series. We'll surely see another one one day. WE JUST WANT TO KNOW HOW IT ENDS.

Half-Life: Origins comes from the same team behind the excellent Beyond Black Mesa short film released earlier this year. It's a short but evocative take on those famous first moments of the original Half-Life, the peaceful train journey before all that nastiness with the interdimensional portal, and the aliens, and the crowbar. It captures the workmanlike atmosphere of Black Mesa quite nicely, though the chap playing Gordon keeps reminding me how perfect Hugh Laurie would be for the role. Infectious Designer should ask him to do their next film, I'm sure he's not busy.

As reported on Gamasutra, a bunch of Valve's writers have been taking part in a roundtable question and answer session at GDC Online.

Read on for some insight from some of the most talented writers in the industry.

Valve might be famous for its use of silent protagonists but according to Mark Laidlaw, one of the writers at Valve, it can be a restrictive on a studio's creativity: "Now that some of Valve's most popular protagonists are silent, there’s no turning back. “At this point we’re fully committed to it and taking it as far as it possibly could go.”

Eric Wolpaw, another writer at Valve, also provided some insight. Referring to Valve's hugely successful free to play game, TF2, he said: “that whole game is us desperately trying to keep our jobs."

“Comedy stuff is tougher because it’s more subjective and it’s really hard to gauge peoples’ reaction," he said. Wolpaw added that sometimes it’s a bit depressing, when people playtest a part in a game that’s supposed to be funny, and there's little reaction. “Pretty much no one that played Portal 2 cracked a smile, but testers still said the game was funny... It’s hard to tell if a joke is failing or not.”

Laidlaw was equally humble when referring to his own work: “We fail all the time, we just don’t advertise it too much...we always want to feel like we’re on the edge and challenging ourselves and growing all the time.”

So now we know that Gordon Freeman will return in Renegade Ops. We can't say exactly why, but we can show you what he'll look like. See three new screenshots of Gordon's buggy in action below, along with some new artwork in which Gordon has a bit of a glare, perhaps a bit irate at how long it's taking for Episode 3 to come out.
