So I logged in and It was night time, It was just bright enough to play without needing a flashlight out, which is just how I like it. I looted an M1911 and a crossbow from a little town then I started moving east along the coast. I was running along and I hear some muffling behind me, along with someone saying "Hashy..." in a whispered tone.(Which gave me a mini heart attack) I whip around and aim down my sights, Nothing from what I can tell. I thought it might be someone in a Ghillie suit trolling me so I started backing up. Again he calls my name, and I hear more muffling. I still can't see anything so I answer back with "Hi". He asks me if I want something good... Confused, I agreed, not quite sure what he was talking about. He told me to check my bag, sure enough, NV goggles. (First pair I'd ever had) After that he was gone and I didn't hear from him again. I was pretty sure he was a hacker, but I put on the goggles and kept going east. They didn't do much good; I could already see pretty well. After a few minutes I came across a small compound I had been to before, I went in and started looting. A minute goes by and I hear "Hey haaaaashy...where are you?..." In a whispered tone, except this time it was a different voice. I heard footsteps behind me but nobody was there, I kept running around while he tried to get my attention. At one point in a small doorway he was in my way, my char stopped and I couldn't move until he moved. I debated shooting the area where I knew he was but with only 2 clips in my M1911 I figured I would just save my ammo. I decided to log out. So....I assume these were hackers, running around invisible messing with people.Can someone shed some light on this? Also, If I know exactly where they are standing would shooting do any good?
