Maybe you’ve noticed that Valve loves to release cute little movies about their video games. Now, they’re getting ready to release the tool used to make those movies. It’s called Source Filmmaker, and it’s an animation studio suite that can use any prop, character, or setting built for the Source engine. You know, like Half-Life 2, Portal 2, something something Team Fortress, maybe you’ve heard of those games? Destructoid has the story.
