If you are farming simulator purist then this map is not for you, because this map has many tasks to do instead of cultivating, harvesting, feeding animals etc.
This map it is a modification of Bjornholm.
What is new in this map:
This map has a mine where you can extract stone, limestone, sand and coal.
You use the stone crusher for the production of gravel and you use a limestone crusher for the production of cement.
With the gravel you can extract gold at goldmaster, and sell the gold in the ATM machine nearby the tractor shop.
With the gravel, sand, cement and water you can produce concrete at the concrete factory, and sell the concrete in the construction area, also you can sell sand, gravel, cement and concrete slabs.
The concrete slabs has automatic production and you don´t need to make nothing for production of concrete slabs.
The coal can be sold at the biomass power plant or in the lime factory.
In the port you have a lime factory where you can produce lime to apply on soil instead of liquid fertilizer or manure.
