If there is one model we need, it's this Spy model.
Exactly the one I was thinking of, too. Also makes me wish I could edit model/animation files so I could get this mod and have it boxtrot properly. Though, maybe if this maskless spy makes it in, it'll mean some clever person will have done that for me?
I found a better Shrek model to replace the current one. It has better quality and lighting, doesn't replace all of the weapon taunts with the Frankenstein Heavy taunt (and doesn't replace the Conga with the old unused version of the Kazotsky Kick), and doesn't have the weird floating Donkey.
