Desert Oasis is a map from the Cities: Skylines Sunset Harbor DLC.
The entire map is on an expansive desert, with various hills and oases scattered.
Towards the southwestern part of the map is a lake surrounded by mountains.
Despite having 76% buildable land, the undulating terrain can make things a little more complicated.
Unsurprisingly, there’s very little water on this map.
The inland water treatment facilities from the Sunset Harbor DLC will come in handy here, so you won’t have to dump sewage into the few bodies of water you have access to.
Your starting tile on Desert Oasis provides a large amount of flat land, and dunes towards the eastern edge.
There’s a small oasis in the southwest for your water source.
You’ll find strong winds (enough to get 8MW from a wind turbine) in the slopes in the eastern part of the tile.
Desert Oasis has three out of the four possible external connections: highway, railway, and air.
There is no ship connection as it’s a landlocked map.
There are highway and railway connections both in the east and west of your starting tile.
As for air transport, the irregular terrain on this map means you may need to spend a bit of money on leveling land for your airports.
Desert Oasis isn’t a particularly good map for early-game specialized industry as natural resources aren’t abundant.
For example, there isn’t a usable amount of fertile land on this map. Alternatively, there is a small patch of forest resources near the various oases (including the one in your starting tile).
There is a good amount of ore if you’re willing to expand towards the east of the map.
And although not abundant, there is enough oil on this map to make it viable if you really want to extract it locally.
This map has few bodies of water, but you will find anchovy in the oases, and anchovy and shellfish in the lake in the southwest.
The four possible tiles you can choose from for your first expansion are fairly similar: all entirely dry land with some undulating terrain.
Since none of these tiles is particularly easier or more difficult to build on, you can make your choice depending on which part of the map you’d prefer to build towards (e.g., the lake in the southwest, or the mountains and ore resources in the east).
The tile north of your starting area gives you access to an external highway connection.
Purchasing this tile will get you close to the highway intersection as well as the oases in the northwest.
This tile is a good choice if you’re interested in making use of the railway in the east, or build specialized industry on the ore resources near the eastern mountains.
This tile has some oil deposits if you’re looking to start an oil industry.
It’s also an option if you’d like to start expanding your city towards the lake in the southwest.
Purchasing the tile west of your starting area opens up a few options. After purchasing this tile you can either go for the oases north of it, or start expanding towards the lake south of it.
