To be honest, things don't always work. I got shot with a mosin while trying to protect someone in my group in chapervask, and it did a solid amount of damage. I was grey shaky and nearly dead..I stopped the bleeding, and had a few blood bags on me and a couple salines iv bags. I gave one of my partners 2 of my blood bags and a saline it hardly brought me back to color and my vision was as if I was 2 bottles of jack deep. And instead of wasting more of the precious gear, I just had a friend shoot me and I recovered my old body and got all my stuff back.I'm not sure if that was a faulty/buggy situation or else the healing system hasn't been introduced properly. Maybe tomorrows update will help.
