I will only defend myself if you shoot first. I have 550 hours now and my favorite thing to do is key runs.
I place a door blocker, barricade, and a jolt mine every time I do it. No explosive mines, no surge coils to get you to fall to your death, I always carry defibs and will always voice chat to say hey I'm friendly but it's my key my room please leave I won't shoot.
Yet some people always break through the blocker, take down the barricade, and start yelling slurs when I kill them when they're jolted.
My keys. my loot dude. If you knowingly break through my first two barriers, don't get mad when I don't think you have the best of intentions. PvP ain't my main playstyle, but when I shout hi and I hear nothing, don't expect me to sit here and lose my key room loot just because you can't take a hint. You are now the loot in my key room.
