It seemed initially like the Source Filmmaker community might be content to make only short and silly videos, but there's now a growing selection of long and silly videos starring Team Fortress 2 [official site] characters. The one that's making the rounds today is The Winglet's Live and Let Spy, a 20-minute epic that starts out with sneaking but escalates until chaos erupts. Watch it below.
For a fan project, this is absurdly well-made. It's not quite got the hand-crafted animation polish of, say, my beloved and Valve-approved End of the Line, but there's no single moment where it looks bad, either. It's also one of the few community-made TF2 shorts I've seen that manages to use the game's class dialogue in a way that doesn't feel stilted or awkward, bar possibly that one word where I think the Spy talks in the Demoman's voice.
Really, I'm nitpicking: this is good, and absurdly so when you consider it's made almost entirely by a single person over the course of six months. Using free software! And it's free to watch! What a world. Look at this cool poster for it, too.
Thanks, PC Gamer.
