The unitypackage contains the fbx file as well as all the textures that you see in the images, it also has a particle system on it for blood dripping from it and the drops collide with the floor they make a tiny blood puddle for the drop. Poiyomi shader is recommended to get what I have made.
You can get poiyomi for free here on their githubpage: https://github.com/poiyomi/PoiyomiToonShader/releases/tag/V8.1.165
