Would not mind if there was some sort of debuff for killing other players, increased zombie awareness, or more zombies flocking to the location to investigate. I find it a little appaling when attempting to gather some supplies(getting bigger backpack at a supermaket etc), when i get to the area and find people just sat on roofs for the sole purpose of killing you. Not to gather supplies themselves, but killing everyone else who is making a shot at it. At the same time, i am playing on norwegian servers currently, and have only ran into other people two times that have not just shot me down on sight(this despite me having a mic, and yelling out friendly). Personally id rather not shoot first, and then ask questions later, but sadly that appears to be what you should do at the moment if you are going solo. Still, im very much for players being able to kill eachother, and would not change that for anything in the world. Its possibly what makes this game so great. But it does feel like you should get into an organized group from the get go(sort something with other players on a forum etc). And then proceed to exploring and attempting to progress within the game. I am still a rather new to this game however, and have lots of places to explore and go. Not to mention, a ton of things to learn.
