well, yeah, the fading may be accurate, but i guess you weren't shooting someone with a rifle while you had your attack.
You are loosing your strength rapidly, probably are panicking, have incredible pain shooting through your body and according to the 3rd-person-animation you are holding your weapon in one hand, not really the best condition to put a pinpoint-shot at the guy 50m away covering behind a wall.
Yeah exactly, I was slumped back and couldn't even move my arms, all I could do was act hysterical before I went fell over unconscious...sound also continued for a few seconds while it was black, I could hear my girlfriend screaming, then it abruptly cut to silence and I could think for maybe 1-2 more seconds before total nothingness consumed me.
Oh yeah and the muffled sound that kicks in when youre dying that sounds kind of like youre under water is EXACTLY what happens too...sound is the first to go, although not completely. its just muffled and you really can only hear bass.
Additionally, it is possible even to be shot in the heart and keep motor control for a few seconds before dying. My father was shot and killed by some gangbanging piece of **** in 1993 who unloaded a .357 into the back of his moving car. He drove maybe 100-200 yards, took a left turn, and then probably died here...but his vehicle continued down another block before his car smashed into a bunch of trees where they found him dead. I tend to think he may of been conscious, as keep a car straight on the road for an entire block without hitting anything on the side (houses, trash cans, parked cars would be difficult, especially if the alignment was even slightly off.
By the way...the vehicle was a ****ing shift. So..yeah you can do very little even with a fatal heart injury.
