I'm new at this game (only have about 5 hours played) and started during 1.7.3 I think, basically being brand new and having the Zombies aggro to anything and everything it took me a llllong time before I was finally able to start getting weapons and food and stuff with every character. As such I just really, really wanted to murder someone in game lol. I got my Lee Enfield rifle and went back to the spawning area. I went prone over some rocks and shot the first person I saw. Sorry but I just had to, it let out a lot of frustration I had experienced those first few hours. I got it out of my system now though so the only people I'll shoot on site are people in any of the big towns or out in the wilderness carrying a weapon.
