Yeah I think he means the hit marker sound. I like how it elevates in pitch or octaves letting you know that they're almost dead. Kinda makes the survival experience more intense but a new sound would be cool. Most games actually use a quick hit sound. Kinda a fast millisecond punch or tick sound And not a high pitched note.
But if you changed that then you might as well change the sound when your health is rejuvenating like different sample grunge breathes like your trying to get a hold of yourself and keep composure. (Imagining Arnold Schwarzenegger in movies when he gets hurt

) Or maybe even a fast paced heart beat sound with the red damaged U.I. overlay. (That would be just as intense if not better.) If Reason would permit it since I purchased the software I'd make tons of sounds myself and by using their sound bank. But using their sound bank I think only license me to use them and not put them in game. Don't know.
