At first, it was a reskin mod for the Scout by AyesDyef. A few months later, Rebbacus and MaxofS2D reworked the model for special uses in Max's videos, featuring enhanced faceposing and new textures. This enhanced model, while playable, was not intended for use in Team Fortress 2. It's most prominent in Earthbound Fortress 2, sporting yet another reworking of the original model.
