downloaded the default fov file,the revolver and glock sound didn't change, shotgun aim point changed and shotgun sound only the load and double shot sound changed, rpg only changed the sound of the explosion, and the tau canon overcharge sound didn't change. other than this I don't know any other errors, but there are other sounds that have changed besides the weapon sound, but I like them, so I won't make this a problem, I think you should check your files, but apart from this, it's the best Black Mesa sound video I've ever seen thank you
