I played now for a while the madness I set up with this server and I think it might be helpful to set up a beginners guide.
Feel free to add your own experiences.

Some general and most important things you always should keep in mind:

• Keep an eye on your body temperature!
• Keep an eye on your hunger and thirst status!
• Plan your route wisely! You won't get far running around like a headless chicken!
  Check out what you need next most urgently.
  Time is against you, when you are going to starve you should be already on your way to the next area where you might find some food...

A good way to start:

Spawn at Vorkuta and move on to the Old Yard
Arm yourself at this spot and grab as many weapons you can.
Beware of zeds here, they climb ladders and the towers can be death traps.
You also might encounter bandits here.
You might check the supermarket at Vorkuta City, but main cities are dangerous, because of the amount of zeds and roaming bandits...
I always traveled from the Old Yard directly and on the shortest way to the trader camp. Don't waiste time on this 4km journey, you will start freezing on your way if you don't find enough heatpacks.
Always watch out for bandits and grab everything you can on your way to earn your first (few) pop tabs.
Once you warmed up there, move back to the Warehouse north of the camp. It's only 800m away.
You have good chances to find some food and drinks there. Repeat some loot runs and earn more pop tabs and don't travel too far at the beginning.

Of course it's much easier to spawn at Norinsk, but at the Old Yard you have good chances to get a bunch of weapons and ammunition.

I recommend to buy a quad as first vehicle.
I managed all right to behave like this:
Drive offroad, avoid main roads.
When you come near a spot with buildings, recon the area from the distance to check if bandits are around.
Leave your quad at this spot and move on by food.
Zeds and of course bandits can damage and destroy your hard earned vehicle.

In general reconnaissance is important, so you don't get ambushed.
You have much more to loose here, so think twice what you do and where you go...think about what you would do in reallife and react like that!
