Cities: Skylines - Avanya
Greetings, fellow city-builders, and welcome to another Sunset Harbor Dev Diary! This time we'll check out the free content coming with the update.

Overground Metro
Imagine a busy city center, people walking towards a metro station and a metro train passing by in the background... That's right! One of the most highlyanticipated features, the overground metro, is coming to Cities: Skylines! Now you finally have the ability to build street level metro tracks or even raise them off the ground entirely! Plus, there are two new metro stations and a brand new metro vehicle as well. The new stations can naturally be connected to your old metro lines and underground metro network. These new buildings unlock at Milestone 6.

Since the metro vehicle model now looks more realistic and is longer than the old one, some changes were made to the underground metro stations and pathfinding. This feature won't affect old saves, however you won't be able to make the tracks turn as sharply as was previously possible. Metro lines can still be created the same way as before, by selecting the line tool and adding nodes on metro stations. You can change the elevation of the metro tracks with the same old Page Up and Page Down keys as always. Have fun planning new overground metro lines in your cities!


Elevated metro station takes citizens to new heights.

New Healthcare City Services
As a part of the free content update, we offer a place for all elderly people to gather and spend time together, take part in hobbies and get treatment for the various ailments old age brings. Studies show that placing an Eldercare facility in your city increases the health of all elders, heals sick elders and increases the average lifespan of all citizens. Building Eldercare buildings might also attract more elders to move into your city.

In addition to looking after the elderly, there is also another healthcare city service. The Child Health Center increases the health and, ultimately, the happiness of all children and teenagers in the neighborhood and increases the birth rate nearby. There is also a high chance of a sick minor getting cured when visiting the building. Together, these new additions come with a new Advisor text and an updated Health infoview.


Eldercare and Child Health Center to care for the elderly and children.

Improvements
On top of the free content mentioned above, Sunset Harbor also includes lots of smaller improvements. The biggest of them all is the Tutorial Message Log. You know how sometimes you forget a tutorial text that popped up a moment ago and you want to read it again more thoroughly but can't find it anywhere? Well, now you can access all unlocked tutorial messages from a neat new log! The Tutorial Message Log can be found in the pause menu. It even comes with a search bar and categories to make searching easier when there are lots of unlocked tutorials.


The Tutorial Message Log stores all tutorials.

Another handy new feature is the possibility of loading a game and having it start in a paused state. No more rushing to pause the game immediately after loading. This option will be on by default, and you can turn it off anytime from the Gameplay Options. The camera position can also now be saved when saving the game. This means you get to continue exactly where you left off when you load a saved game. If you save the game while zoomed in on a certain building for example, you will continue from the exact same place when you load the game again.

Placing buildings on curved roads and slopes has also been made simpler with more flexible building placement. Building onto the inside curve of a curved road, for example, is not challenging anymore. Building pedestrian paths is easier now, too.

And last but not least, we have walkable quays. Quays can now be edited in the Asset Editor to allow pedestrian paths on top of them. This makes quays work like pedestrian paths, which is a nice addition to city-planning and allows for detailing the shoreline in-game.

And this wraps up Sunset Harbor DLC Dev Diaries! In addition to this free content, there are a lot of new features available ranging from the Fishing Industry all the way to Trolleybuses, the Waste Transfer System and Inland Water Treatment Plants. Are you already excited for Cities Skylines: Sunset Harbor? It's coming out soon, so you can already start planning on how to incorporate all these neat features into your new or existing cities!

Greetings fellow city-builders and welcome to another Sunset Harbor Dev Diary!

This time, we look at new maps and policies as well as the new unique building, all of which are coming in Sunset Harbor. Let's start with the maps!

Maps
Sunset Harbor introduces five new maps to the game. The maps differ from each other significantly, and each one brings along new challenges into your city-building. Are you ready to take the first steps and start on this journey that will take us from serpentine river filled swamp lands all the way to something we've never done before in Cities: Skylines, a desert? Join us!

Located in a large, open bay area overlooking the vast ocean, Azure Gulf offers good outside connections by ship. With small lakes and several rivers of various sizes, Azure Gulf is an ideal place to start a booming Fishing Industry. This temperate map is also rich in ore and forests.


Azure Gulf

With its Boreal theme, Crater Falls is a large crater area surrounded by a mountain range with several trickling rivers flowing into small lakes in the middle. Cliff faces rising from the riverbeds, ever flowing rapids, deep lakes and beautiful waterfalls all invite fishers to come and seize the day and take their pick from the different types of fish the waters hold. In addition to providing good Fishing Industry possibilities, the mountains are rich in ore and there are plenty of forests and fertile land areas between the rivers.


Crater Falls

Made possible by the new Inland Water Treatment Plants and the Water Tower, Desert Oasis is a map with no flowing water. Surrounded by an endless desert hiding only a few oases, this map offers a completely unique place for a city. With so little fresh water, the Tropical Desert Oasis may not be best for fishing, but the dunes are rich in both ore and oil.


Desert Oasis

As the name suggests, Fisher Enclave is a great place to start a Fishing Industry. With huge bodies of still water surrounding it, Fisher Enclave consists of several small and a few larger islands. This European themed map filled with forests offers mainly two kinds of fish. Just be careful, as the still waters are easily polluted.


Fisher Enclave

While its defining feature are the flowing, serpentine rivers carrying every type of fish, Swamplands also offers large flat areas suitable for building. This map with a Boreal theme is rich in forests and fertile land. Take care, though, as you might accidentally make the rivers overflow, flooding large areas of land.


Swamplands

Policies
Sunset Harbor also includes 6 new policies, four of which are fishing related. The Fishing License policy creates residential tax income from the city selling affordable fishing licenses to its citizens. The policy unlocks at Milestone 3, and it increases crime and decreases citizen happiness by a small amount. With the Sustainable Fishing policy, the fishing industry can take steps to ensure that the fish population sizes stay at healthy levels. This increases the price of fish sold but lowers the fish yield, as fishing boats leave more fish in the ocean to minimize the environmental impact. With the Dolphin-safe Fishing policy, the fishing industry adopts new techniques to ensure minimal dolphin fatalities resulting from fishing. This increases citizen happiness but also lowers the fish yield. Sustainable and Dolphin-safe Fishing both unlock at Milestone 6. When Algae-based Water Filtering is enabled, the water service network uses algae as a natural filtering system. This policy is unlocked after an Algae Farm is built and Milestone 5 is reached. It increases the purification level of drain pipes and water treatment plants but also increases the water facility upkeep cost and decreases algae farm production.

After building an intercity station or terminal, you can increase bus-based tourism with the Tourist Travel Card policy. The city's tourism department then starts a campaign to increase tourism in the city by offering affordable intercity bus tickets to people living in the surrounding cities. This increases the upkeep costs of the Intercity Bus Station. The Airplane Tours policy is available after building the new unique building (more of which in next part of the diary). By opening its door to tourists, the building's attractiveness and entertainment are increased. The downside is higher levels of noise pollution. These two city policies unlock at Milestone 6.

Aviation Club
Now is the time to finally reveal the new unique building. Can we get a drum roll, please! Sunset Harbor's unique building is the Aviation Club! It consists of a small terminal, an air traffic control tower and a runway for light aircraft. Planes take off, fly high into the sky, circle around the city and land safely back on the runway. Local aviation hobbyists and owners of small planes can use the field as a base for recreational flying within the city's limits. The Aviation Club also attracts tourists and increases the city's attractiveness and entertainment. Once unlocked at Milestone 6, the building is found in the Unique Buildings build menu, under Level 5 Unique Buildings tab.

That's all for this Dev Diary. We hope you are as excited about the new maps and the unique building as we are! Tune in again next time when we look at the upcoming free content.

Hello! Welcome yet again to another Cities Skylines: Sunset Harbor Dev Diary! So please, stay a while and... read!

In this Dev Diary, we'll be taking a look at the Waste Transfer System and Inland Water Treatment features coming with the Sunset Harbor DLC!

Waste Transfer System
The Garbage city service is getting expanded with a Waste Transfer System feature. Players have at times experienced difficulties with the Landfill site's reach or the fact that it creates highly polluted areas in the middle of the city. The Waste Transfer System is an upgrade to the base game's garbage service, and it focuses on solving these problems and improving the gameplay in relation to the Garbage city service. While the base game Landfill Sites and Incinerators, along with Green Cities DLC Recycling Centers, can be used alongside the new Waste Transfer System, the new system's core idea is to make handling garbage easier and more flexible without compromising the city layout as drastically.

The Waste Transfer System contains a Waste Processing Complex and a Waste Transfer Facility along with two new vehicles, the Waste Transfer Truck and the Waste Collection Truck. With the new additions, you can build a Waste Processing Complex far away from your beautiful city and extend its reach by building smaller, less polluting Waste Transfer Facilities in the city.

If you have either the Sunset Harbor or the Industries DLC enabled, you will find that the Garbage build menu has been renamed to Garbage and Industry and that's where, under the Garbage tab, all the new Waste Transfer System buildings can be found once they are unlocked at the Grand City milestone (9).


A Waste Processing Complex in a spot perfect for processing garbage: far away from the city, in a industrial district.

When you have unlocked the Waste Transfer System buildings, you can begin using them by building Waste Transfer Facilities at essential locations around the city. When facilities and landfills are getting full, it is a good idea to build a Waste Processing Complex, which will begin sending out Waste Transfer Trucks to pick up garbage from any Landfill Site, Recycling Center, Incineration Plant or Waste Transfer Facility. It is worth noting, however, that a Waste Processing Complex can't work on it's own, as it doesn't collect garbage directly from buildings, only from other garbage-storing facilities.


Waste processing chain differences between base game garbage service and the Waste Transfer System.

The Waste Transfer System will come in handy for example when the city is looking to expand, when the roads are getting filled with garbage trucks, or when landfill sites just can no longer reasonably keep up with the amounts of garbage the city produces. By having Waste Transfer Facilities scattered across the city, garbage can be collected from buildings more swiftly, while a centralized Waste Processing Complex then handles the collection of garbage from those temporary holding sites. This keeps pollution away from city and saves up space for more zoning possibilities.


A Waste Transfer Facility can operate safely even in residential neighborhoods.


Inland Water Treatment
The Inland Water Treatment Plant is an expansion of the Water service, and it enables you to build cities completely inland, far away from open water sources. With the Inland Water Treatment Plant, your city can process waste water without pumping sewage into lakes, rivers or the ocean. The Inland Water Treatment Plant does create high ground pollution however, so placing it next to residential areas or bodies of water is not advisable. Advanced variants of the Inland Water Treatment can process higher quantities of sewage while creating less ground pollution. The Eco variant produces even lower ground pollution levels but also has a lower drain capacity.

The Inland Water Treatment Plant and all of its variants can be found under the Water and Sewage build menu. The Inland Water Treatment Plant and the Eco Inland Water Treatment Plant are unlocked at city milestone 0. The Advanced Inland Water Treatment Plant is unlocked at city milestone 8, and finally the Eco Advanced Inland Water Treatment Plant is unlocked at milestone 10.


Large Water Tower compared to its smaller sibling.

The Inland Water Treatment Plant is built on land, alongside a road. It can be connected to the water network simply by building water pipes to its connector node underground, in the exact same way as every other water pump, tower and drain pipe. Once functional, the Inland Water Treatment Plant starts generating ground pollution around the building but purifying the water.

Also included in the extended Water city services is the Large Water Tower. It shares the same functionality as the base game Water Tower, but has a much higher pumping capacity! And just like the base game Water Tower, the Large Water Tower can be placed anywhere on the ground. Once placed and connected to the water pipe and electricity networks, it will start pumping water. Ground pollution affects the quality of water, and if water is pumped from an area with ground pollution, citizens will become sick.

With these additions to the Water and Sewage city services, cities can now also form skylines even in places where plenitudes of water aren't available!


An Inland Water Treatment Plant and its Advanced version take care of the sewage but produce a lot of ground pollution! Better place these away from the city!

And that wraps it up for this Dev Diary. We look forward to seeing you again on the next one, where we will be taking a more in-depth look at the new maps, policies and the new unique building!

Your Colossal Order dev team

Greetings, fellow city-builders, and welcome to another Sunset Harbor Dev Diary!

As the previous diary was dedicated to Trolleybuses, we think it's a good idea to follow it with even more public transport services coming to you in Sunset Harbor.

Intercity Bus Service
Intercity Bus is a public transport service that opens up a new outside connection. In addition to transporting tourists, the Intercity Bus Service also makes traveling easier for your citizens and ultimately decreases traffic, as people leave their own vehicles at home.


There's something to it when you travel by night, with home waiting in the distance.

The Intercity Bus Service unlocks at Milestone 6, but you can already see intercity buses on the highways at the start of the game. The new intercity bus station and terminal are located in the same build menu tab as the local bus service. There is no need to create any stops or lines, just build an intercity bus station or terminal and you can notice intercity buses making frequent stops at your city. This new service also comes with a brand new intercity bus vehicle model and an updated Public Transport Infoview. Adjusting the old bus budget slider also encourages people to use intercity buses more.


An intercity bus station in the morning.


Passenger Helicopter
The next new public transport service takes citizens to new heights. Passenger helicopters circumvent traffic altogether and zip through the sky, connecting people in a whole new way. This service unlocks at Milestone 11, right before airports, and uses the same build menu tab as other Air transport services. The new assets that unlock with the service are the helicopter vehicle model, helicopter depot and helicopter stop. There is also an updated Public Transport Infoview and helicopters are added to the existing Air Transport budget slider. To start building your first passenger helicopter line, you first need to place a helicopter depot that sends out the helicopters. Then you build as many helicopter stops as you want and connect them with the new Helicopter pathway tool. Don't forget to connect the depot to one of the stops because helicopters can't move without pathways! Lastly, you can create helicopter lines by selecting joined Helicopter stops with the Helicopter Line tool. There are also two helicopter stops in one of the new transport hubs we are going to talk about next!


Connecting a Passenger Helicopter Depot to a Helicopter Stop using the Helicopter Pathway tool.


Transport Hubs
You read it right, we are adding new transport hubs to the game! There are five new hubs in total coming with Sunset Harbor. Transport hubs connect different transport networks together, making changing from one transport type to another easy and fast without the need to walk from one stop to another. All new hubs are added to a brand new build menu tab together with the older hubs. Transport hubs function the same way as public transport stops: If a transport hub has been built and is connected to a road, train track or metro track, it can be used as a stop when creating a public transport line.


Train-Metro hub, at your service!

Here are short introductions to the new assets:
  • Bus-Intercity Bus Hub utilizes the new intercity bus service introduced above and connects it to the good old local bus service. Bus lines can be created on the bus platforms and citizens can change between local and intercity buses with ease. At Milestone 6, this hub is the first of the five to unlock.
  • Metro-Intercity Bus Hub combines the intercity bus service with an underground metro network to get your travelers all around town! This hub unlocks at Milestone 7.
  • Bus-Metro Hub connects the local bus service and two metro networks together. You can see citizens taking the escalator to the metro and hurrying to the bus platforms as they change lines. Unlocks at Milestone 9.
  • Train-Metro Hub has two large stations connected together by a road and a bridge over the road that makes it easy for train passengers to change to a metro line. But hang on, is that an overground metro line? More about that in the Dev Diaries to come. This beauty unlocks at Milestone 8.
  • Metropolitan Airport brings with it the largest building to Cities: Skylines so far! This hub wraps together an international airport, two underground metro stations and two landing pads for the passenger helicopter. This colossal building unlocks at Milestone 13.


The Metropolitan Airport will bring citizens together from around the world.

With these hubs, we've tied together all the new public transport services. The next Dev Diary is going to focus on completely different city services. We hope you liked these new features and are looking forward to the next ones!

Until next time, city-builders!

Cities: Skylines - Avanya
Greetings fellow city-builders and welcome to another Sunset Harbor Dev Diary!

Ever since Cities: Skylines was released, we have received hundreds of requests for one specific feature: Trolleybuses! And to go along with every one of those requests, vivid debates took place within the community about whether or not trolleybuses are too hard to implement, if the feature is “too niche” or if “they” actually ever even read the suggestions posted on the forums.

Let us assure you that we are indeed constantly listening, and every single idea is considered when we are deciding what to do next! Also, we are just as enthusiastic about public transport as you are, and you would have to be very creative to suggest something that we would consider to be “too niche”

The reason trolleybuses have never been added is their technical complexity. Trolleybuses are basically “trackless trams”: electrical buses that draw their power from overhead wires. Unlike trams, they utilize two wires and two trolley poles to complete the electrical circuit. And like a normal bus, a trolleybus is able to change lanes and stop on the side of the road. As the bus is moving, its poles rotate and tilt to stay attached to the wires. In the game as well as in reality, the trolley poles are the most tricky part of the whole system.

We are glad to inform you that we have managed to overcome the technical challenges, so Trolleybuses will finally be available in Cities: Skylines – Sunset Harbor!


They are finally here!


The trolleybus system in Cities: Skylines – Sunset Harbor consists of four components:
  • Trolleybus Depot
  • Trolleybus Roads
  • Trolleybus Stops
  • Trolleybus Vehicle
To get started with trolleybuses, you first place a Trolleybus Depot. After that, you can place Trolleybus Roads and create Trolleybus Lines with roadside stops. Your depot will then send out trolleybuses to operate the lines. It is important to remember that the trolley poles must be attached to the wires at all times, so your Trolleybus Depot and your Trolleybus Lines must be connected by Trolleybus Roads as well!


Trolleybus Depot sending out new trolleybuses.


Taking passengers over the river.

That’s the easy part! In the second part of this Dev Diary, we would like to shed light on what we did to make the trolley poles behave realistically. Unlike other diary entries, this one will be slightly more technical. Even if you are not that math and geometry savvy, we still hope you enjoy this inside look!




The Wire
Let’s take a closer look at the roads! On every road segment, you will find three catenary masts: One at the start, one in the middle and one at the end. The electrical wires span the masts, and with some mathematical calculations we can find out the start and end coordinate of each wire section. Let’s call them and (using a small arrow to mark them as 3D vectors).

A mathematical formula to define the line of the wire would be with and

When the bus is on the road segment, we want its pole to connect to the overhead wire defined by the mathematical formula above. is the coordinate where the pole is attached to the wire.

The Trolleybus
The game knows how the bus is positioned and rotated in the world, and from that it is possible to calculate the coordinate where the trolley pole is attached to the bus. Let’s call it !

The trolley pole is made of sturdy metal, so it cannot stretch. That means the distance between the coordinate where the pole is attached to the bus () and the coordinate where the pole is attached to the wire () must always be equal to the length of the pole. Let’s call it and define this formula to
take that into account:

The Equation System
By inserting the first formula into the second one, we end up with a single equation with a single unknown variable c :



With a few tricks we can transform it into a quadratic equation:

Step 1: with
Step 2:
Step 3:
Step 4:
Step 5:

We can use the quadratic formula to solve the equation.
We will get zero, one or two values for c :


Note that there will be no solutions if the part in the square root is negative (which happens if the wire is too far away from the bus). Note that the solutions for c calculated by this formula could also be out of range (), so we have to check that as well.

Choosing the Right Position
By inserting and into our wire formula , we can calculate two theoretical pole-wire-attachment coordinates and . One will be above the front part and the other above the back of the bus:



As the pole of a trolleybus is typically facing backwards, we need to find out which of the two positions is the correct one.

Haven’t had enough of vectors yet? Let’s define a few more:

  • - the direction vector of the bus (points into driving direction)
  • - direction the pole would face if it was attached at (points from to )
  • - direction the pole would face if it was attached at (points from to )

Using the dot product, we can easily find out if and one of the pole vectors are facing into about the same direction (> 0) or the opposite direction (< 0).

We are specifically looking for the pole vector that faces in the opposite direction of , so our conditions would look like this:

  • - If that condition is true, is the correct pole-wire-attachment coordinate.
  • - If that condition is true, is the correct pole-wire-attachment coordinate.

Rendering the Trolley Poles
Uh, that was a lot of math! Now that we know where the pole is attached on the bus () and where the pole is attached to the wire (either or ), it is possible to render the pole in the correct position and rotation.

As we learned, a trolleybus has two poles (otherwise the electrical circuit would be incomplete), so we will just repeat the same steps to draw the second pole.

And now you know what kind of stuff goes on behind the scenes to render the poles! Of course, in order to make trolleybuses realistic, this was just one small portion of the overall work that was needed!


The last shift of the evening.

Once again, we've reached the end of a Dev Diary. We hope that you liked this insight into the development of Cities: Skylines and that we didn’t scare you with all the formulas! Gotta say, the end result is really mesmerizing. We could just watch the buses circle around for hours! What do you guys think about the trolleybuses?

Until next time, city-builders!

Cities: Skylines - Aiwyth
Greetings fellow city-builders! It's time to tune into another series of the beloved Cities: Skylines Dev Diaries!

As you already know, Sunset Harbor, the next expansion for Cities: Skylines, was announced on the 19th of March. In the upcoming days, we are going to take a more detailed look at all the cool features we have been working on. But first, let's start by going over what the Sunset Harbor expansion is all about and the types of new features it introduces. If you haven't already checked out the trailer, you can follow the link here or watch it below.



Cities: Skylines Sunset Harbor DLC is an expansion that, instead of improving only on a single aspect of the game, brings with it a multitude of features that address several different things. We start off these Dev Diaries here by introducing one of the key features of this expansion, the highly sought-after addition of Fishing Industry that will surely liven up the shorelines of your cities! In future Dev Diaries, we will be introducing the improved and extended mass transit options as well as the expanded Waste Transfer System, Inland Water Treatment and Healthcare city services. To top it off, we introduce a new and amazing Unique Building, cool new maps, policies and miscellaneous improvements, because we all know you can't have an expansion without them! This expansion is simply going to take your cities to the next level.

Our new maps are designed with the new Sunset Harbor features in mind. They offer challenges in the shape of sewage treatment management, provide good opportunities for fishing industry activities, and showcase memorable landscapes to build cities on. The paid part of this DLC allows you to expand on Waste Management with the Waste Transfer System, offer your citizens new mass transit options with Trolleybuses, Passenger Helicopters and Intercity Buses, and have them all utilize new Transport Hubs. The free part of this DLC, includes a majorly overhauled metro system. You can now adjust the height of metro tracks, which means tracks and stations can be underground, street level, or even above ground on elevated platforms! Included in the free content update are also the new Healthcare facilities. After building them, you may notice more children being born in the city and some citizens living slightly longer than others.

Now that the general introductions are out of the way, it's time we roll up our sleeves and dive right into the fish puns. Actually, let's try to keep those to the minimum.

What fish-tastic news!

Adding life and meaning to the vast shorelines, Fishing Industry is a new addition to the industry selection of Cities: Skylines. It is a type of industry separate from the Industries DLC and neither production chain requires the other in order to function. In Sunset Harbor, you take control of the fishing industry in the city and can manage it from simple fishing route planning all the way to final commercial production. You build fishing boat harbors, plan fishing routes for different types of boats and nurture fish farms on the shoreline (preferably away from polluted waters). The fish yield from these is then delivered to either Fish Markets in the city or to the Fish Factory, where the fish is turned into canned fish and delivered to grocery stores for increased profit.



You can locate the new Fishing Industry features under the same construction menu as Garbage, on it's own Fishing Industry tab. A Fishing Industry Info View was also added to the (already long) list of Info Views. It can be used to determine what types of fish live in the waters surrounding the city. The Info View shows fish types, water pollution, and existing fishing routes in different colors and also highlights the fishing industry buildings. The Outside Connections Info View now also highlights fish resources, but keep in mind that fish can only be exported!


The Fishing Industry Info View provides valuable information about water pollution, fish types, fishing routes and fishing buildings.

It's time to go fish!

After reaching milestone 3, Fishing Industry unlocks and you are able to cast your first nets! In the beginning, you can build a non-specialized Fishing Boat Harbor and define fishing routes for the boats it houses. The Fishing Harbor comes with a built-in road, similar to other harbor buildings, and it has two builtin fishing route nodes ready: one for outgoing boats and one for incoming boats. From these points, you can create the route with a special fishing route tool. Draw the route as you see fit, and connect the route to the other node on the same harbor to close it. The route shape and length is entirely up to you, and multiple fishing routes can overlap each other!


The world is my oyster.

With a completed fishing route and a functioning Fishing Harbor, fishing boats are sent out to catch fish automatically. The boats can catch any type of fish, but the catch rate is only moderate and the storage capacity is low (it keeps the fishing industry running but doesn't give much of a boost to the city's economy). A boat's speed is determined by its current action: when it is catching fish, it moves slower. When it is at full capacity and returning to harbor, it moves faster. Caught fish can either be exported or transported with Fish Trucks to a Fish Market and sold directly to consumers.

As the combined fish yield from all of the city's fishing boat harbors increases, further Fishing Harbor unlocks become available. With careful fishing route planning, this process can be significantly sped up. Fishing boat harbors unlocked later all come with their own fishing boats, each dedicated to a certain type of fish. The catch rate and capacity of these specialized boats is high, but they catch fish only when sailing in an area that contains the type of fish specific to them. If the fishing boat's route passes through areas that only contain the wrong type of fish, they won't catch anything. Fishing route efficiency can be seen by selecting the harbor and opening the building panel.

The first Fish Farm unlocks at city milestone 5, allowing you to grow and gather higher yields of fish. Further Fish Farm unlocks are tied to the overall fish yield of the city's fish farms, much like with Fishing Harbors. Fish Farms are an alternative way to gather fish and also make it possible to farm seaweed and algae. Fish Farms are a more efficient way to gain high yields of fish and sea plants, but their stationary nature makes them particularly vulnerable to water pollution. Fish Farms work well in small lakes however, where creating efficient fishing routes is not feasible. Fish Farms operate on growth cycles, which can be seen by selecting the farm. During the cycle, the meter fills up. Once it is full, the building is ready to send its yield to either a Fish Factory or Fish Market. If neither a factory nor a market exists, the fish is exported out of the city.

As mentioned, water pollution affects fish yields in the polluted area. With boats, the catch rate decreases as water pollution increases, until finally they stop catching fish entirely. You need to either remove the pollution from the water or plot new fishing routes that circumvent the polluted waters. With fish farms, cultivation stops immediately if any pollution is present.


Note to self: Fish Farms and Sewage Outlets don't mix well.

How much is the fish?

So, how do we know what types of fish thrive in which conditions? In short, fish type is determined by the depth and flow of water. Sunset Harbor features 4 types of fish, all of which prefer different conditions. Anchovies thrive in still, shallow waters, salmon prefer shallow water with a flow, shellfish require deep and still waters, and tuna need deep, flowing water. This means one single map might not always have the required conditions for all types of fish.

Fishing Boat Harbors and Fish Farms have a limited capacity for storing fish, so in order to gain profit, the fish needs to be transported by Fish Trucks to either a Fish Factory, where the raw food material is processed into goods, or to a Fish Market where the raw food material is sold directly to citizens. Direct monetary compensation from fishing is received from Fish Factories and Fish Markets when their products are sold to the end users or exported. But monetary compensation is not the only benefit these buildings offer: the Fish Market gives surrounding citizens a health benefit and entertainment. In the budget panel, you can inspect how the fishing industry is performing, how much running the industry costs, and how much profit it generates. Happy fishing!

Sunset Harbor will hit the stores on the 26th of March, and we are hooked on a feeling of excitement about this expansion! To help the wait, tune in for more Dev Diaries published here every day. We hope to see you on the next one, where we will show you the kinds of new public transportation options we have to offer!
