Invisible zombie kill... or was it?

[PhillyT 554]

People mention the invisible zombie kills all the time, but I am not sure that is what just happened to me.

 

I was in the lumber yard at Berezino, had just sprinted past a couple zombies on the school and was at the cement wall looking around when I heard a melee thump and suddenly went to grey vision with lots of blood, like an axe hit.  Strange right?  They were military zombies I had passed, but they don't hit that hard do they?  I ran to the building on the coast, looking behind to see if someone struck me through the wall.  I then heard what sounded like a gun shot and a bullet strike near me.  I ran around behind a fence into a position nobody in town could have seen and heard another shot and bullet strike.  I ran into the building, up the stairs and into the upstairs bedroom.  I bandaged and raised my shotgun to the door.  

 

I then heard another thump and got the "You are dead."  statement.  I almost assume I was being shot with a mosin.  THe damage is roughly that (like half life at a torso shot), but the melee thump confused me.  The killing blow happened away from windows and in a closed room.  I suppose the person could have backed away from the house until they managed to see me, but I think I would have heard the gun.  Likewise, they could have shot me through the floor, but generally, again, you would hear the gun rapport.

 

Does this sound like some glitch with the invisible zombie I have heard so much about?  Seems unlikely given the gunshots I was hearing, but either way, things were behaving strangely.

Got killed by an invisible zombie yesterday at Green Mountain

Spawned in after a server reset on experimental

And heard the zombie sounds but didn't see anything.

Zombie sounds got more and more clear, than all the sudden my character started doing the animation they do when they get hit, and I fell unconscious

I heard the zombie, but I have never seen zombies climb those sorts of stairs and the door stayed shut (not that our current zombies care about doors!)
