I honestly believe you should be automatically forced into 1PP and have the HUD disabled as soon as you enter unconscious.

Something like this maybe???

while(Player.IsUncon){
//force into 1pp
//force HUD disabled
}

• • This is for immersion purposes and authentic (as in real life, you would be knocked out and not be able to know what your health status or blood is at, etc.)
• Locking in 1st Person keeps away the abusive exploitable 3PP peaking (especially for calling out enemy positions) when you can see again in the periods of vision you get through the unconsciousness cycle

Also, Zeds should not target as 1st priority and attack unconscious players. Every time a gunfight breaks out near zombies, every unconscious player will die for sure :/ which ruins the exhilarating moments of getting back up mid-gunfight half dead from 5 minutes + of unconsciousness!

Oh yeah, longer and more random unconscious times would be great!
