The world around you.
Where it is safe to stand, what the sky is doing to you, and what the server throws at everyone at once.
Zones.
The map is divided up, and the zone you are standing in decides how hard it is trying to kill you.
Safe
Traders, storage and a place to plan. Nothing spawns on you here and you cannot be shot at.
Livable
Ordinary ground. The infected are around, but the pressure is low enough to build and hold something.
Radiation
Health drains the whole time you are inside. Bring protective gear, take what you came for, and leave.
Everywhere else
Outside the mapped zones the world stops looking after you at all. This is where the better loot is.
Weather.
Weather is not decoration here. Three of the seven kinds do something to you directly, and you can see all of them coming.
| Sky | What it does to you |
|---|---|
| Clear | Nothing. Travel while it lasts. |
| Rain | Wet and dark. Harder to see, harder to be seen. |
| Mist | Visibility collapses and the fog carries sound. You will hear things you cannot place. |
| Storm | Heavy rain and lightning across the map. |
| Radiation rain | Takes health every few seconds while you are out in it, and leaves you nauseous. Get under cover. |
| Supercell | Constant lightning and wind strong enough to drag you off your line. Tornadoes form inside it. |
| Nuclear fallout | Poison and hunger for as long as it lasts. The worst sky the server has. |
Events.
These fire on their own timers and everyone online gets them at once. Some are an opportunity. Some are a reason to be somewhere else.
Supply drop
A crate lands somewhere on the map, every half hour to an hour. Good loot, and everyone else saw the same announcement you did.
Zombie horde
The most frequent one, every fifteen to thirty minutes. A mass of infected arrives somewhere and starts moving.
Roaming horde
Fifteen to twenty-five infected walking a route behind a dreadnought. Do not try to hold ground against it alone.
Bombardment
Shells land across an area for a while. Being indoors helps. Being elsewhere helps more.
Two that arrive another way.
Tornado
Not on a timer — a supercell throws one. It touches down about sixty blocks away and stays for two minutes. If the sky has already turned, you have had your warning.
The nuke
A player sets this one off. Everyone online gets a countdown on their screen before it lands, which is the only reason anyone survives it.
