I used a gmod reskin for the original zombies. After a few weeks i wanted the original ones, so i could get this addon to work. However i could not find a download for zombie hl2 skin, I tried to GCFScape to get the hl2 model but it did nearly work, torso and all zombie skins EXCEPT, the original zombie (note torso version of this works!) are invisble. Can someone provide a download link?, And no i dont not have pirated.
In GFCSpace, it should be Classic.mdl
I used GFCScape, and tried that. Anyways i got it work
