I am pretty sure that the dude who did this is a hacker. As you can see in the screenshot, all the gates are closed and there are no holes in the Palisade wall. However, a man somehow managed to make it inside the Palisade and kill everyone in it. I don't have the character's full name. All I can remember from when I asked why he was doing it is that he said something that started with 'Red' and that he was from Ainran. I know Ainran is a village of murderers, but now I'm pretty sure they're hackers, too. There is no way he got inside through the gate. I personally made sure that it stayed shut the entire time I was inside. I would have seen him come inside if I had it open, too. He killed this alt soon after I took the screenshot, too. Now then, I know that people will say that I should just get over it and play the game or just rage-quit. I've already died at the hands of Ainran raiders many times by now. This time, now that I'm sure he hacked to kill me, I'm complaining.
