you could drop in a brightskins pak and then do cl_noskins 1 to force every enemy model to grunt... unfortunately this isnt so nice in teams if ya ever play them cause it forces BOTH teams to grunt q2pro supports cl_noskins 2 which will force people to either athena or grunt so it works for teams... but in otdm there is tskin and eskin options rambling aside, i believe the option you would like would be just get a brightskins pak and drop it in ely posted a sweet one awhile back but it might be a little annoying to find now
Wouldn't mind having that purple female skin. Where can I find it Reflex?
