The AP rounds in this game are useless.
Today I was running around the coast wearing a pristine plate carrier w/ a VSS loaded with 9x39 Armour Piercing Rounds. I had spotted two random guys chopping some trees down next to a road and both of them had plate carriers. I decided to take my chance and snipe one of them and I hit his friend 6 times (!!!) and he STILL SURVIVED, like WTF?
He went unconscious after the 5th round hit him, and just to make sure, I hit him with 1 more round (which you can clearly see in the video) to put him down. His friend comes up to me and mows me down with a RAK from a distance and I go unconscious. Somehow not a single bullet hit him. What the hell is up with the bullet damage values in DayZ (???) and will this terrible hit registration ever be addressed?
I immediately respawned near by and I witnessed them looting my body. Somehow they both survived unscathed and were sprinting around as if nothing hit them.
