How do you navigate through the open world? There is no IG map/coordinate system so most of the time I just randomly run
if I'm really lucky I find a compass, you can find maps of chernarus but they're next to useless. Honestly I just keep this map:
http://dayzdb.com/map/chernarusplus open in my browser and alt+tab out to check where I'm at. All the proper towns have signs outside them, so I check the english translation of the Cyrillic and find out what town I'm at and how to get to wherever I want to go. It also has the airfields and military bases, and icons for where spawns are and what generally spawns in each area. Super helpful. If you don't have a compass, you just have to figure out where the sun is (can be tricky, and sometimes it's in the north or south which is really weird) or keep to the coast, ocean on your right is north and left is south. I like to stick to the train tracks when I first spawn because they take you to good towns no matter which way you go, and when I'm drunk I make train noises in public chat and roleplay as a train.
The map below is mostly accurate, except the wrecked ship in the north east almost always has an m4 or a mosin, along with clothes and food, if you don't mind getting your shoes and pants damp. Also the interior towns in the "food trail" have a lot of barns and piano houses, which spawn a lot of rifles (shotguns, mosins, double rifles, or sks's), ammo, and melee weapons. Sometimes pistols too. Schools almost always have handguns or rifles, usually with ammo, in the back room on the third floor, and/or at the topmost roof.
This thread is also really helpful:
