So if you get an instakill and there is only one zombie left in the round and you do not kill it, you get althe green smoke and then the zombie can't hit you until the start of the next round? Can anyone try this out and confirm?

Not to sound rude but how about you try this out, confirm this and then make a thread. Thanks.
