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.

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.

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.”

What's your favourite example of writing in games? Let us know in the comments.

In the fast-paced world of PC gaming, Half-Life 2 may be considered 'getting on a bit', but its fan base still stands strong. No better evidence could be found than this great fan-film, telling the story of a resistance fighter opposing the rule of the Combine.

Found by the guys over at RPS, Singularity Collapse features some spectacular looking props and costumes that perfectly capture the atmosphere of Valve's iconic shooter, as well as some great CGI work using assets from the game itself. Gunfights and aesthetics aside though, it's really the gunship vs buggy chase that makes this a must-see.
