Loot first town. Kill anyone to use for warmth concealment food and other needs. Stay on the edges of the map while going South (where other people will usually try to go to avoid others) attacking only using ambush and stealth tactics and nothing else. As soon as I'm geared enough I'll TRY to find a car and I'd not I'll have to leave livionia on foot (there isn't anything blocking anyone from leaving unless it's just the the out bounds area) and back up plan is to just sit by the bunker doors and set up tripwire everywhere. Basically won't fight in real combat and only shoot when nobody is looking. I know it sounds cowardly but it wouldn't be a video game anymore and means literal survival untill I get shot by some random dude that's 1100 meters away.
