I just joined an UK server (so night), and started to make my way along some rails. I lost nearly all my supplies in the water, so I had to be careful. I found a barn, but a zed was guarding the entrance and I didn't want to risk any more of them by popping it. So I decided to follow another trail, and I was in the middle of the field near some woods. Suddenly someone said "hey". Didn't shout, was perhaps even whispering it, I don't know. It scared the shit out of me. Then a lot of chat messages came in saying "that scared me". It was just some guy on the voice channel. This game will give me a heart-attack at this rate.
