Generic character for prototype games

them0nster

does anyone know if there are any free generic models out there that are good for prototyping a game? I don't care as much about textures, but having a bipedal character with a basic walk animation would be great. I was hoping to use a model like this to prototype a couple ideas i have for games in unity3d, xna, or UDK.

so far i have just been using boxes. white box for the hero, and green boxes for the zombies.

thanks
