Its a persistent cooperative scenario for dedicated server, the player start on a little island near the main island of Napf.
The players must gear up and recruit an army to be able to defeat a mysterious faction called LFDA.
To be able to recruit an army the player must build a colony in predefined area, if there enough structure the recruitable friendly survivor will join your colony.
The basic item and the structure (house) are buidable at the workbench in your colony, the main ressource are the junk pile, they can be find every where but you can build only junk house.
The other component must be find and refined, for exemple to be able to build better house or better defense wall the player must find a stack of cinder block and transform it into concrete wall at the concrete factory.
The crafting component are heavy, so they cannot be transported in a bacpack, the lighter item can be carryed and loaded in vehicle, a truck is required to transport the biggest item.
The house can be loaded in the vehicle and unloaded, once placed they cannot be carry, the player must repeat the process if he want to move an house (load/unload in vehicle).
For more information read the description below. Its a persistent scenario, cargo content (mag, food...) and static object (building) are saved between each server restart, more explanation at the bottom of the description.

 Persistence  
To save your progression the server admin need to be logged and copy this line in the chat box : #gradpersistenceSave. Or use radio menu (0-0-Save) So every vehicle, vehicle cargo, tent content, crate content and static object will be saved, at the settlement (blue circle).
The crafting component (car battery or stack of brick) are considered as static object and will be saved, but they must be unloaded from the vehicle before saving, if they are not unloaded they will be lost.
