Since its launch, Valve's Source Filmmaker has helped budding directors create literally hundreds of movies - some good, some bad, most.... incredibly goofy. The Team Fortress 2 cast especially has sung seemingly every song, played out every meme and worn every hat and every expression - sometimes at once! But what are the ten best creations? We've scoured YouTube in search of the funniest, the most dramatic, and the just plain prettiest Source Filmmaker movies.

Scout vs. Witch



Easily one of the best directed SFM movies out there, mixing Team Fortress, Left 4 Dead and a fine sense of timing. Scout (no relation to Scout) is one of the more popular TF2 mercs, with his cockiness the perfect antidote to all that zombie misery. At least, while the moment lasts.

Just One More Hat



And he's back, in this fashion-conscious spin on one of Disney's most parodied songs. More worksafe than Dirty Little Mermaid, more morally conscious than Slaughter Your World, it also wins bonus points for having an original TF2 version of a song instead of just looping in a more general one.

Meet The Family



Mostly made (naughty naughty) with the leaked SFM, this was one of the first epic projects to be finished and still one of the best. Scout and Spy team up as literal brothers in blood to kick off a perfectly choreographed race for that all-important Intelligence. Guest starring music from The Incredibles to add pace and more than a little style. No "da-da-da" sting at the end though.

Adventures Of The F2P Engineer



He's smart enough to whip up teleporters and sentries on the battlefield... but he didn't pay for the privilege, so he's probably doing it with his flies open and his shoes undone. When he's having this much fun though, can you really begrudge him? The answer is yes. Even if you're on the other team, sometimes it just gets... sad. Luckily, there are other engineers on hand, like...

Practical Problems



An epic war between two professionals who know what they're doing, but don't know when to quit. A little parable about the importance of good manners, respect, and most importantly, not ****ing with another man's sandvich. A true Lesson For The Ages, with some fine music right alongside.



Meet The Soldier (Directed By Michael Bay)



We're firmly back in parody territory for this one; a relatively straight replay of Meet The Soldier, but with rather more boom and a surprising (though not unwelcome) lack of Alyx, Zoey, Rochelle or Chell forcibly being draped over a motorbike or anything at any point to complete the picture of one of cinema's most successful nostalgia murderers. Love or hate it, it's better than Transformers 2 any day.

The First Wave



It's not just a game mode... it's war! Mann vs. Machine gets dramatic in this epic four minutes of the mercs facing their durable doubles for the first time. Bonus points for a return of the disembodied Blue Spy, and a death scene with the power to spawn a thousand bits of erotic TF2 fan-fiction. Which exist. You'd better believe they exist. You have been warned.

DOTA Hero Pals: The Mysterious Ticking Noise



Not so much a 'parody' of the Potter Puppet Pals original as a straight copy with DOTA characters in it, this is still one of the more accomplished movies to come from that game. We just need another eighty or so instalments to cover the other characters, and I see no reason new players shouldn't have enough data to compete at professional level/troll like champions.

Heavy Doo, Where Are You?



I never understood "Scooby Doo, Where Are You?" as a show title. Admittedly my memory is a little fuzzy about the actual cartoons, but I definitely remember Fred, Daphne and Velma doing most of the mystery-solving gruntwork, with Scooby's role being to blunder into helpful things. If you called him, you'd prevent him from doing that. The song makes no sense, is what I'm saying. This movie is more reasonable. If you had to fight Old Man Peterson, having a Gatling wielding Russian psychopath on hand definitely beats anything Scrappy Doo could serve up. Admittedly, so would a crouton.

After Aperture



Chell's life after Aperture isn't exactly unexplored territory, but this Exile Vilify backed slice is one of the more interestingly melancholic SFM movies so far. A little clunky in terms of animation, largely due to the poor Chell rig (at least one other movie opted to reskin Zoey instead of using it), but it makes up for it with a different kind of atmosphere to most and that lovely outdoor setting.

Those are our picks, but there are many more SFM movies out there. Have any particularly caught your attention, impressed you, or just made you laugh? Share their names below...

It's not often you spot a softly glowing sign warning of gravity-changing crystals in puzzle-platformers, but Vitrum fills that niche nicely. On the e-shelf today from developer 9head Games, the indie puzzle-platformer shuffles up the house that Portal built with an array of power-granting crystals, a suitably bloom-ified tech motif, and a throbbing ambient electronica soundtrack worthy of space hibernation.

Solving Vitrum's Rubik-like room layouts involves harnessing energy from various crystals found during your travels. Most of the granted abilities -- a short air dash, a push of energy, and so on -- allude to solutions entailing timing and carefully aimed jumps. The real draw is the ability to combine the powers surging in each of your android hands and the almighty gravity crystal that exchanges floor with ceiling on the fly. There's a cliff-sharp ramping of puzzle difficulty -- it's no easy task to gyrate into a tiny cubby hole surrounded by deadly red crystals after simultaneously air dashing and watching the room spin sickeningly. Good luck.

Vitrum carries a pay-as-you-like price on Gumroad with a requested $5 minimum for covering overhead.

Let's kick off this Friday morning with one of the cutest weapons of war you'll ever see - a Portal 2 turret that replaces its guns with flashing lights, but otherwise acts just like the turrets in the game.



While nowhere near as nice, if you want your own turret, Gaming Heads is selling one in very limited quantities. As for other Portal merch, ThinkGeek on the other hand would have been your place to go for an authentic, though sadly non-functional Portal Gun, had it not sold out of them 30 minutes after saying "So, we have this..." A few other options are still around though if you don't mind paying a little more to have your very own Aperture experience.

Cake and jumpsuit sold seperately. Literally.

Note: This post originally suggested that the one in the video was the Gaming Heads model. This turned out to be inaccurate, so has been changed. Sorry about that.

It looks as though Valve are working on a proper follow up to the Source Engine they've been gradually improving over the course of the last decade. Valve Time have pulled numerous references to a "next-gen 'Source 2'" engine along with various "Source 2 tools" icons from the guts of the Source Film Maker.

Valve have previously played down the need for an entirely new version of Source, and have concentrated instead on updating the original version to keep up with modern engine tech. That's worked quite nicely so far, but if these references are correct, a more significant step up is on the way. Here are a few of the pulled strings referring to Source 2.

------------------------------------------------------------------------
def setEngine( self, version=ENGINE.SOURCE ):
'''
Set the engine version for the project, i.e. 'Source 2'
------------------------------------------------------------------------

------------------------------------------------------------------------
Line 1387:
'''Return an str with the current engine version.
If key doesn't doesn't exist, assume 'Source', otherwise invalid -- assume next-gen 'Source 2'.'''
------------------------------------------------------------------------

Exciting stuff. But it wouldn't be a post about Valve and the future without somebody saying something about Half-Life 2: Episode Three. Is the reason that it's taken so long that it's being built in a more advanced engine that will explode our minds when it's finally released? I have no idea. Here are the icons that Valve Time discovered. Look at that high fidelity hammer. Oooo.

Way back in December 2009, when this humble intern was an even humbler college sophomore with no job who was sinking scores of hours into Dragon Age: Origins, we reported on a guy who goes by DemonStrate beating Portal in a touch over 10 minutes. While that seemed astounding at the time, the record has since been smashed to pieces by SourceRuns, demolishing GLaDOS in just 8:31. That's a good minute and a half faster than DemonStrate, and 53 seconds faster than their own previous record-breaking run. See the video for yourself below.



"To be SDA legal we have done our run without using scripts/cheats/hacks for any portion of the run," the speed demons posted on YouTube. "This run first started after the discovery of a new glitch, which snowballed into a whirlwind of discoveries of new tricks, skips, and glitches. We started running chambers in April, took a brief hiatus, and then resumed work in late June. The bulk of the run was completed in about 2 weeks time."

This is a picture of a panel that, on Friday, will be bolted onto the Japanese HTV-3 resupply craft and hurled into space. The craft will ferry supplies to the International Space Station and launch a little bit of Portal 2 into the cosmos. A post on the Portal 2 blog spotted by VG247 mentions that an anonymous NASA tech managed to burn the tiny picture of Wheatley space core onto one of the craft's panels. "Please note that when we mentioned an "anonymous tech at NASA" we weren't kidding: NASA in no way officially endorses secretly laser-engraving characters from Portal onto their spacecraft," say Valve.

On which note, if you happen to be a NASA engineer with access to a laser-engraving machine, and you just happen to accidentally burn the PCG logo onto a panel and then send it into space then I'd like to say that we'd absolutely keep it a secret, and definitely wouldn't post it everywhere on the site and then look at it and burst out cheering every day forever. JUST SAYING.

Now, because space is brilliant, here's a video that Tom spotted over the weekend made up of pictures snapped from the International Space Station in low Earth orbit. Prepare to have the tingly awe receptors in your frontal lobe tickled ... NOW.

Update: Thanks to those who have pointed out that it's the space core. The Internet Error Police will be here shortly to perform a routine disintegration. My last request is for someone to laser-etch "I should have written SPACE COOOORE" onto my tombstone, and then fire it into space.

Remember the prototype for a Portal 2 Lego set that we mentioned a few weeks back? It was submitted on Lego Cuusoo, a site that hosts idea pitches for future commercial sets. If an idea gains enough followers it's forwarded to a "review stage" where giant Lego men poke it to see if the idea's viable, and then gradually rotate a huge, C shaped fist to deliver a clumsy thumbs-up or thumbs-down on the project.

Portal Lego has now reached that stage! Will it succeed? Who knows. It's impossible to know what's going on behind those fixed ever-smiling faces. It's out of our hands now, but we can still look at pictures of the prototypes, which are probably the cutest thing on the internet right now. Take a look.

UPDATE: Rabbit Island is in fact the cutest thing on the internet right now, but Portal Lego takes a close second place.

Speaking to Eurogamer, Portal 1 lead designer Kim Swift has explained that there are a couple of bumps in Valve's otherwise-flat management structure.

"They have management, there's the board of directors of the company, there's Gabe Newell" she explains. "Those guys at the top of the company definitely have opinions on how things should be run."

It's a slightly different picture to the one described in the Valve Employee Handbook, which a few weeks ago gave us a rare glimpse into the workings of the famously private developer - but it's doubtful that Swift's claims will surprise many people.

Her statements moderate Valve's own depiction of itself in a way that makes a lot of sense. "There are definitely people behind the scenes making decisions for the company" she says. "To me, that's normal."

What she says doesn't necessarily contradict Gabe Newell's recent interview with Bloomberg Businessweek, where he explained that Valve describe their employees as individual and group contributors rather than managers and employees. A flat system still provides room for people to exert influence, and it's no surprise that this is apparently the case at Valve.

Swift is currently working on dimension-shifting first-person puzzler Quantum Conundrum at Airtight Games, and she stresses that she parted from Valve on good terms. "I still have a great relationship with those guys."

The Portal 2 puzzle creator will let players make their own test chambers without having to dive into Valve's complex level creation tools. We got a chance to catch up with Chet Faliszeck and Erik Johnson at GDC for a chat about Valve's plans for the user friendly level editor. "I believe they’re beta testing it right now," said Erik Johnson. "When the puzzle maker comes out, you will have a lot of content, that’s for sure."

Valve announced their plans for the Puzzle Creator on the Portal 2 site last year, where they released the first couple of screenshots. It looks very similar to the animated diagrams of the first Portal trailers, released way back in 2007. Much, much friendlier than Valve's Hammer editor.

Valve are expecting a rush of new maps when the new tools are released. October's Portal 2 post mentioned that Valve were also planning "a community site to host all of these player-created puzzles." The recently released Steam Workshop can do just that, presumably players will be able to use the Workshop to show off their levels and vote on their favourites.

"Correct," said Erik. We can expect to see Steam Workshop support appearing in other Valve games, too. "You’ll see the Steam Workshop coming from there, then to Left 4 Dead and then we’re going to keep using it," Chet Faliszeck added. "It’s not just for the modders, it’s for the players. It’s a super easy way to consume the creations of other people that are just really hard to do otherwise."

There's no release date for the new tools yet, but if it's in beta testing, it can't be too far off.

Not all of Valve's discarded ideas are great, the binned competitive multiplayer mode for Portal 2 is one such example, but some of them are. The video above is from a Valve talk at GDC in which they discussed many of the ideas that never made it into the full game. This scene was originally Portal 2's opening.

There were many more great ideas left on the drawing board. In fact, the whole game was set to pan out very differently. Eurogamer sat in on the conference, and describe out Wheatley was originally supposed to stay dead when Glados crushes him near the beginning. Rather than being a persistent companion, he was merely the first in a series of personality spheres you'd meet as you travelled through Aperture's labs. Other spheres included a paranoid AI and one that Valve's Eric Wolpaw calls "The Morgan Freeman sphere."

Players were originally supposed to find the Morgan Freeman sphere sat on a lonely stand in the middle of an empty room. "He'd been sitting on that little pedestal for a few centuries, and he was just incredibly, incredibly wise" said Wolpaw. "But only about the 20 by 20 space that he was in."

"As soon as you dragged him 22 feet out of the room, his mind was blown and he was pretty much useless. Although as the game progressed, he eventually got his feet under him and started delivering some homespun wisdom that all related back to this 20 by 20 space." Valve discarded the extra orbs when they found that players didn't bond to them as well as Wheatley, the first sphere went on to become an integral part of Portal 2's plot.

Valve were also planning to have several endings scattered throughout the campaign. "We had these parts throughout the game where Chell would die and that would be the end and we'd play a song, and if you wanted to you could just quit there." Wolpaw told the audience. "We had one that was like two minutes into the game, and if you died there, there was a song that was just about reviewing those first two minutes."

They also had a few other ideas. The next bit contains spoilers for the end of Portal 2, in case you haven't played it yet.

Initially, there was a scene part way through the game in which you'd catch a glimpse of the moon. To trigger an early death you could portal up there to "asphyxiate while listening to a sad song about the moon." Valve eventually dropped the multiple endings because they felt as though they didn't have enough good ideas, but the moon went on to become Portal 2's memorable finale. According to Wolpaw, it was the "perfect mix of being totally awesome and completely stupid." It's hard to disagree.
