Two mutant wolf models to choose from, including custom sound effects. It is a rare mutant and can be found in the Red Forest, but some few have already been seen in Army Warehouse and Radar areas.
Wolf1 (chimera based animation) - author is unknown / Vk.com
Wolf2 (default wolf animation) - author: ferr-um / Stalker-mods.clan.su
Check the preview images for each of the available mutant wolf models, then copy the corresponding "gamedata" folder into CoC dir, overwrite files if asked.
A new game may be required so that the changes can be applied into the game when you install a mutant wolf for the first time, because this addon uses a custom squad_descr.ltx file so that the animal can spawn in the game.
It is natively compatible with the Komar, Fly and Bear (always install the "newer" addons on top of the "older" ones). To play also with the Tark, please apply on top of everything the included compatibility patch.
