While I was working on a Half Life Resource Pack I thought of modifying the Zombie texture to make it an actual skin, it turned out like this!

Headcrabs are Xenian parasitic creatures, they latch on their host's head and take over their entire bodies in around a minute, the host becomes what's pretty much just a Zombie with a weird thing humping it's head.

As you should know, these things come from Valve's Half-Life. You HAVE to know that, if not you've been pretty much living under a rock.

This skin is 100% based off the Zombies from Gold Source, so it should be as accurate as a pixelated and blocky model can.

If I find any missing details I'll just update it, however I made sure to have most of them done.

I hope you like it! :D
