ok theres no way you could even see a persons health.. the most you can do is see the damage you did to that player.. sometimes itll give u a crazy number, I know of a couple of times I looked down after I was killed to see that I did sumthin like 200 damage to there head an yet I still was killed.. you have to take into effect there use of armor, heavy vests, 35%helmets an stuff like that..
