I thought I'd give the retexture of the good old classic zombie a try.
Improved clothing, better shirt, jeans, shoes. More detail on skin and organs. Also improved the headcrab.
I made my own sounds, all except the moving and hitting sounds got replaced (only for zombie though).
Video (note: shitty quality in confront of the actual skin, sounds at the end!!!!!)
Comes with 2048x2048 maps, bumps and reflection maps for zombie and headcrab.
