Wow, so once you start reviving someone, its kind of like or "do or die"? Lol. For me, I dont know if i've just played enough zombies to do this but, when the rounds start getting intense and people start going down, im able to "sense" the zombies when reviving someone. Like, if I start reviving someone and im halfway done, in my head, im able to "feel" like if im going to get the person up or not. Its hard to explain. The next time I do it, i'll try to get it recorded and show you guys.
