Arctic Zombie Sounds

Brings the sounds from the first Entropy : Zero's arctic fast zombies to Entropy : Zero 2. We are in an arctic region afterall! Note: This does not include an arctic zombie skin, but there is another workshop item of that. https://steamcommunity.com/sharedfiles/filedetails/?id=3000063272 Fast Zombies in glowing goo (or the fast_glowbie) have separate sounds and this will not affect them. I just copied these over from my install of Entropy : Zero. I found the vector fast zombie image in a search and kept the watermark for the artist (though it looks like their page is dead) if you made it, let me know, esp if you want me to take that down. Entropy Zero was made by Breadman. Let me know if I missed anything in my crediting.
