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...

Ninjas taught us silence is the language of assassins, but a half-crazed, blood-soaked theoretical physicist demonstrated silence works just as well for everyone else. Although Dishonored's Corvo Attano and Half-Life's Gordon Freeman share a common penchant for reticence, Arkane writer Austin Grossman told Kotaku he's rooting for his creation more than Valve's beloved hero. Why? "I find Gordon creepy as hell," he stated.

"I hate what Valve does with the silent protagonist," Grossman explained. "I find it incredibly awkward and really creepy. The difference between Dishonored and how it works in Half-Life 2 is that it's a lot more personal. I think you get that involvement because the character has personal relationships with people from the beginning. And it's very clear that people have f***ed with you in a very personal way."

Grossman contrasted the differences between Gordon's silence as a coping mechanic against the events transpiring in City 17 and beyond with Corvo's intentional muteness as an emphasis for the message conveyed through his actions. Grossman says Gordon's encounters involve people "talking at him, about him, and sometimes even for him. He just happens to be in the middle of this whole thing."

"I'm biased, of course, but I think Dishonored grips you much more viscerally and emotionally," he continued. "And that's on purpose. Corvo doesn't talk, and I think it works because everybody knows what Corvo would have to say, His actions form a sort of speech, something like, 'If I could kill the people who screwed with me...and if that includes you, then I'm going to kill you right now.'"

"This is like if Gabe Newell took acid..." is (the decent half of) one gamer's apt description of Half-Mind, a Half-Life 2 mod released in 2009 which was recently given a boost back into the disco spotlight via a gameplay video by YouTuber "vinesauce." A quick jaunt to Half-Mind's Mod DB entry reveals a terse mission statement of bringing Valve's magnum opus "to the brink of hilarity." It's easy imagining Gordon Freeman's struggles through the Combine's tyrannical grip on City 17 juxtaposed with an insatiable need to make everyone get down and party.

Among other oddments, the recorded footage features a chronically jiggling Dr. Kleiner and a pair of citizens exceptionally talented with communicating through foley. For the truly brave, the mod awaits your download.

Nothing rumbles like the metal mosh pit of a medieval scrap in full swing. After a successful Kickstarter run, Torn Banner's Chivalry: Medieval Warfare expanded upon its origins as a Half-Life 2 mod into a standalone first-person multiplayer slasher with blood-soaked jerkins and jerks soaking in blood. Chivalry's latest trailer, comprised entirely of in-game footage, blasts the mayhem of battle into your eyeballs before revealing an October 16 release date. Have a look above, but we heartily recommend augmenting your viewing experience with the thrash-metal riff of your choice.

Only a few days remain before Black Mesa's Higgs-inclusive LG Orbifold teleportation (thanks, Kleiner) zaps it onto our PCs this Friday, and the team's latest batch of screenshots invokes a similar sense of mystery and alien terror Half-Life's original preview shots carried so long ago. Check out Resonance Cascadians the Vortigaunt, Houndeye, Bullsquid, and Gargantua below.

September 14 is the release date for the first build of one of the most long-awaited mods of all time. The Black Mesa project remakes Half-Life in Valve's Source engine with prettier textures and lighting. Gordon's beard is now super high-res and headcrabs are 20% prettier.

The first release "will include our re-envisioning of Half-Life all the way up to Lambda Core," according to project leader Carlos Montero, writing on the Black Mesa forums. "We believe this is a great way to provide a complete-feeling 8-10 hour experience with a solid ending, make our fans happy and help us make the best overall game possible."

To celebrate the announcement, the mod team have launched an ominous doom clock, the likes of which I haven't seen since way back in July last year. When the clock hits zero we'll finally have the chance to sample the action shown in the official trailer, released three years ago. These recent screenshots offer further evidence that Black Mesa Source is actually happening.
