Welcome to the server, and be weary of the toxicity! You'll feel like quitting at times, but if you stick with it, it gets better.
If you're ever looking for a group to roll with, my gang should be alright with showing you the ropes and stuff. Just let me know if you wanna run with us, and I'll get you set up.
To begin, if you don't want to get robbed:
1) Don't use large trucks, they attract unwanted attention.
2) Illegal runs (include zones with the red circles), and are riskier than legal runs because you have to worry about the police and more attention from bandits.
3) Stay off the MSR (the main road on the map, marked with bright orange).
4) Don't spend too much time in one location, keep moving.
5) Scout before you roll into a red zone, but don't spend too much time doing so.
6) Use the highest caliber weapon you can afford. Most people agree that the Mk-1 is the best 7.62. Promet is the best 6.5 (if we're excluding LMGs)
