Valve Releasing More Team Fortress 2 SDK

Not content with releasing a software development kit for Team Fortress 2's maps and environments, Valve will soon be releasing the SDK for the game's character models and animations as well.

What does this mean? It means modders have access to some of gaming's finest characters and can alter their appearance and movements as they see fit. This will help out now only those looking to spice up the appearance of the game, but machinima enthusiasts as well, as it'll allow them to "have more control over how characters animate in their movies."
