Prussian Peaks is a map from the Cities: Skylines Natural Disasters DLC.
This map has particularly difficult terrain to build on, as the entire land is mountainous.
Rivers wind through the map, and flow into lakes in the west and south.
To build your city on this scenic map, you’ll need to be flexible in terms of working with the constraints of the terrain—or spend a lot of money on leveling land.
Rivers separate the different areas of the map, making building even more difficult (as you’ll need to build bridges for roads and railways).
Fortunately, the population requirements for each milestones are fairly low (e.g., only 320 to reach Little Hamlet). This helps to accommodate for the difficulty in zoning.
Note: This is the same map used in the scenario Alpine Villages, which requires the Natural Disasters DLC to play.
Your starting tile gives you three sections of land separated by rivers.
The land on this tile isn’t very flat, but is relatively easier to build on compared to other areas on the map.
There are some spots along the riverbanks, and one in the southeastern corner, where you’ll find strong enough winds to get 8MW from an early wind turbine.
This map has three out of the four possible external connection types: highway, railway, and air.
There is no outside ship connection.
There are two external highways, which you can easily access as you move into the tiles adjacent to your starting area.
You might struggle to find the external railway; it actually runs along the southwestern portion of the southern lake.
It’s quite far from your starting area, so you’ll need to commit to expanding towards that part of the map if you really want external trains.
Placing airports will be a struggle on this map because of the difficult terrain, so you’ll need to plan ahead (or be willing to spend a lot on leveling land).
Forest is the only resource in abundance here, although there is a small patch of ore near the river and one small area of oil in the north.
But there is no fertile land for farming on this map.
Fishing (Sunset Harbor DLC)
If you have the Sunset Harbor DLC, this is a good map for fishing, as there is fish everywhere in the rivers and lakes.
All four fish types (anchovy, salmon, shellfish, and tuna) are available on this map.
The north tile has some very jagged terrain, and a small section of the river in the north.
It’s an OK choice as a first expansion, but the tile to the east is likely a better option.
This tile is probably the easiest to build on among the four as the terrain here isn’t too steep.
It also gives you access to ore resources, as well as the eastern highway connection.
This area has steep hillsides on either side of a river, which leads to the lake in the south.
It’s flanked by rocky mountains on either side, making it even less appealing for early low-density zoning (when you need the most space).
Most of the land on this map is on a hill. The hilltop itself is relatively smooth and suitable for building.
You’ll also get a segment of the highway connection along the riverbanks.
