Kill everything that moves until your death, that's the real way to do things.
Also you should pvp from the moment you can hold a gun to get more experienced in it, otherwise you are just a high level liability. I got my first taste of tec blood when I was level 3, and never stopped after that. Always armed when scavenging so I could kill more ''tresspassers'' after all why loot when enemies will do it better, and just deliver you the goods ?
Sure you will get killed by more experienced players or deathsquads or swarms of tecs (most Family know what I talk about
), but think of your death as experience and evaluation of your actions during the battle. Next time you will surely do better.
