How to import Game Characters?

Hi i’ve been trying to import a game character from a game called Ark Survival Evolved, i know its possible to do so as ive seen other artists use blender to make them however im unable to find how to import them or even download them, i asked a guy and he said to use UModel but that was it, once again im a beginners at Blender im just trying to make some cool 3D thumbnails
