I went to Green Mountain once when I was still fairly new to the game. It was about 8-9pm and the sun was lowering over the horizon. I approached the inner complex cautiously not knowing what to expect. As I made my way inside, I saw dead bodies littering the area. The stench was awful, but what was even worse was the unsettling feeling that I was possibly being watched. I was carious to the fact there were no zombies. Was somebody already here? I heard what seemed to be clanking metal, or some sort of scraping sounds. It wasn't the music, that shit was turned OFF. I yelled over direct chat if anybody was here. No responses. At this point, it was really dark since I haven't adjusted the gamma or brightness at all, and I had no NVGs. Then I heard some brushing against leaves and went prone in a corner, waiting for whatever it was to show up so I could pop it with my m1014. After about 10 minutes of silence, and almost complete darkness, I decided it was time to crack a flare and I tossed it in the middle area. There didn't seem to be anybody besides me and my trusty shotgun. My food and water were both blinking so I replenished myself.. but while I was in the middle of the animations, that's when it happened.. I heard weird static like that of a radio crackling. It sounded far away but then it got closer and closer. I wanted to log out but I was stricken with fear. Then the static stopped and turned into the most eerie sounding native american chanting, or what sounded like it. Some kind of odd chanting. Then the flare died and I whipped another one, I picked it up and high tailed it out of there as fast as I could. I look back at it and wonder if someone was toying with me using direct chat, however, I don't remember seeing a name pop up. I've never went back since.
