Once each year, Valve hosts a competition, called The Saxxy Awards, to find the best Team Fortress 2 animation. It is named after Saxton Hale, a character from the game's irrelevant (but amazingly well developed) lore that is best known for being an eccentric action hero and executive of a fictional corporation. Its goal is to promote the use of Source Filmmaker and the rest of Valve's user-generated content tools.
This year's overall winner as Animation vs Animator, embed below, where The Scout makes a movie where he torments The Heavy (who responds in kind). The video is likely a reference to the oppositely-named classic series of Flash animations where a stick figure in Flash Professional fights against its creator. Four videos were nominated in each of the four categories, short, action, comedy, and drama, each with its own winner.
