Looks a bit like the HL2 Beta Zombies.

Oh okay, lol. Yeah, I am not seeing any black anything in these screenshots. Lol. Thank you for clarifying.

I just added a screenshot of the back of the zombies.

EDIT: How do you not see the black shirt? Look at the normal hl2 zombie and then look at this one. Instead of white shirt with red blood this is black shirt with red blood.

Eh, there is a new black shirt, only it might be easier to see it if he had a screenshot of his back

This skin is no where else! If your going to say that post a link, but you cant. This is the only black shirt blue pants zombie skin, that I know of.

This work is not yours.I saw this skin on many other sites.

Pros: Gives the zombie a whole new look and makes them a bit scarier. I love it how they blend in with the background. Plus, no head crab. Cons: I don't see any apparent problems with the skin, though it's textures are fairly simple. Improvements: Find some more realistic textures for the shirt and blood. Notes: I give it an 8.5

City 17 zombies are here http://www.garrysmod.org/downloads/?a=view&id=30786 Made by someone else. I do love gmod.org

I don't really see a lot of difference. I do not see a black shirt at all.

I know there is city 17 blue shirts for zombie, can you do it again?

Quite nice, i can said.
