The exact same thing happened to me a couple of days ago, just after the new patch. I was in an alleyway picking some things up and the moment I stood up I fell dead. Full blood, no broken bones. I've been sniped before, not sure how far from, but I still heard the "thwok" sound as the bullet entered my head and passed through spraying a bloom of crimson, creating a large exit wound you could put your fist in. Anyway, I've heard hackers can get in and kill people instantly so that's what I'm wondering. I think we just need to verify if there's always an audible sound when you get sniped.
