Don't mean to bump this thread unnecessarily, but one thing I think would be cool would be a kind of "stabilizing" feature that anyone can do to help keep someone alive whilst awaiting medics.
Essentially, when someone goes unconscious, depending on how it happened, they have a certain amount of time before death, or in some cases, before waking back up.
Clicking R with fists on a body should be how bodies are stabilized, but certain items would be required, depending on the first aid level of the person treating them, and how they became unconscious.
Examples of stabilization differences:
Run over by car: 10 second stabilizing progress bar, reducing as first aid skill improves, and maybe the person treating them needs to use a splint to stabilize them
Shot unconscious: a similar stabilizing bar, but a bandage is needed to bind wounds, etc.
knocked unconscious: depending on strength of assailant, maybe they are just knocked out cold, and wake up a short while later with injuries, but if assailant is super strong, they need to be stabilized.
Now once someone is stabilized, they have a lot longer unconscious before they need to be revived, the amount of time depending on the first aid level of the person who stabilized them. However, if someone is not stabilized within say two or three minutes, depending on injury type, then they will die.
I foresee a few issues however, such as being perpetually stabilized past the five minutes for respawn, which might hold players hostage in the unconscious state for ages, which would be a bit unfair. To fix this, I think after a certain amount of time stabilized, if no medics are on, or if nobody is nearby, then the unconscious person should have the option to die, but only after the traditional five minute timer is up.
Also, firefighters and medics should be considered to have max first aid skill when on duty, simply due to the fact that their roles is focused around that stuff.
Thoughts?
