NoHead

NoHead removes the player's head from the rendered model. The change is visual: the character is drawn headless in both first-person and third-person views, while the game mechanics stay as they were. Hitboxes can shift with the change unless the game engine decides otherwise, so the effect on combat is a matter of how the engine handles the model.

The mod is client-side only, so the server does not need it and players can join a server without installing anything. It works with most character-rendering mods, though it can look stranger when paired with animation mods. The author describes the mod as doing exactly one thing, with no further explanation, and it is released under the MIT License without being open source.
