Pezus,
- Try to find where you are first (when you spawn, you got the nearest city or place at the right bottom corner of the screen under 'Chernarus').
- Use this map http://dayzmap.com/
- Use landscape and forest limits, roads... to find your way.
- Try to reach for barns, or deerstands. You'll probably found more guns in the latest. Sneak out of zombies line of sight and make less sound possible. Or, raid a supermarket, but they're rare and a middle of a city full of zombies.
- You'll find very useful info in the dayZ wiki
I've got a very good gear at the moment, AK74, G17 (hand gun), binoculars, map, watch, matches, ALICE backpack... I have the water can so I'm not dependent on consummables, I can make a fire, gut animals and heal myself with cooked meat so I can now survive on my own !
