Today I saw a most remarkable thing. We gathered, the whole town, filled with anticipation. A breathless silence settled on us, broken only by the clicking of pocket-watches repeatedly checked.

And then, rising beyond the distant mountains, silhouetted against the morning sun, it came: immense and majestic; thunderous and forbidding. A titan of the sky, its lungs enclosed by ribs of metal. I must say, I had the impression more of some noble antediluvian beast, grazing the sky, than of a man-made craft.

I sense a new age dawning, the possibilities stretching as far as the limitless horizon. Untethered from the capricious sea, we can accomplish vast voyages in record time; melt away the distances between nations. But fear grows in me, too; visions of what violence we might wreak on one another, of these vessels we worked so hard to launch into the sky falling to earth once more, screaming plumes of gas bleeding from their ruptured sides.

A new age, indeed. To stand on the threshold between epochs… It is a vertiginous sensation.

Hello Anno Community,

Welcome to our second DevBlog dedicated to DLC 11, “Empire of the Skies”! Previously, we (hopefully) delighted our players and readers with a DevBlog dedicated to Airships, heart and soul of this DLC. Today, instead, we will focus on the whole content and mechanics of the DLC.

Come on aboard, fasten your seatbelts and get ready for the flight: we will be cruising through game mechanics, dev insights and more!

A quick recap on Airships

As mentioned in our Airships DevBlog, with DLC 11 you will have access to two types of Airships: Rapid Airships if you prefer speed over cargo space, and Cargo Airships if you need more space to transport your goods. Airships present different capabilities and features: from transporting goods on your designed trade routes, to worker commuting and drop actions on islands. The first step of your journey into the sky starts with building a Hangar on your island: that is where your airships will be constructed. The Hangar is a monument that needs to be built in 4 phases, each one requiring various materials and quite a bit of workforce – so you will need to be prepared!

New Production chains

Two new elements will be essential for the construction of your airships: aluminium and helium. Of course, this implicates the need for two new production chains.

The new airships are surprisingly lightweight thanks to the aluminium frames that help maintain their structure. Not only is aluminium used in airship constructions, but also for many of the buildings used by airships. Two elements will be required to start your aluminium production: coal and bauxite, with the latter only available in the New World.

These Airships also require a new type of gas, helium, another element that can only be found in the New World, where numerous helium-rich gas pockets have been discovered. The production chain for helium is a bit more complex than the aluminium one. The Helium Extractor, unlike other mines, needs input goods to function and start extracting the gas. The first is lubricant, produced by the Palm Oil Press, which uses two input goods, fish oil and saltpetre, in addition to needing space to plant palm trees. We know you like a good challenge, so you will need to set a trade route to get that precious saltpetre, as the saltpetre works is only available in the Old World. Together with the lubricant, add some clay, and the helium extractor is ready to begin its work!

Airship Platforms

Once you have built your first airship, it is time to build an Airship Platform to maximise the airships’ potential – plus, this way, you will always know where you parked! You can build only one platform per island which can then be expanded with various modules to unlock unique features and capabilities on your island. Platforms can only be built in the New World and the Old World.

There are in total 3 modules that can be built from the Airship Platform menu.

Item Transfer

It allows you to quickly transport items between different islands and sessions. Once the Item Transfer module is built, you will be able to drop any item in an empty slot. The dropped item will then be available after a cooldown on any other island that has an Airship Platform with an Item Transfer module built – however, be aware that the cooldown varies based on the rarity of the item you are dropping. The more Item Transfer modules you build, the more your global storage capacity will increase. Each module you build will supply two additional slots, up to 24 in total.

Airmail Module

This module represents the main mail sorting centre present on your island. It allows you to send and receive mail through airship and their routes. Mail is produced passively by your residents and collected by Post Offices and Post Boxes. Once collected, the mail will be then distributed via airship to other islands and regions. But let us stop here for now, more on Mail and Air Mail Routes later in the blog, just be patient!

Airship Commuter

Shared workforce, anyone? Just like the Commuter Pier, it will allow workforce to commute between islands on which you have built an Airship Platform with an Airship Commuter module.

Based on what your airships are transporting, they will direct themselves to an Airship Platform or other trading spots. When it comes to Mail, airships will unload their precious epistolary cargo on Airship Platforms only, whilst when it comes to other goods, they will approach Airship Platforms, Piers, Trading Posts, etc.

You’ve got mail!

One of the most interesting aspects of “Empire of the Skies” is the Mail System. Nowadays, we live in a hyperconnected world, where everything and everyone is just one click away. However, nothing beats the joy and charm of receiving a handwritten letter from an old friend living on the other side of the world, doesn’t it? An envelope carefully sealed, with stamps methodically placed on the back, or a care package full of our favourite treats thoughtfully picked and placed together…

Mail is a Lifestyle Need for your Residents, and it provides additional income and resident influx. In total, there are three tiers of mail:

• Local Mail – distributed locally on the same island
• Regional Mail – distributed between islands within the same region/session
• Overseas Mail – distributed between different regions/sessions

As mentioned before, Mail is passively produced by your residents and then collected by Post Offices and Post Boxes. Both buildings have a radius, therefore you should place them strategically in your residential districts: the more Residents in the range, the more Local Mail will be gathered. While the Post Boxes are easier to place as they take very little space (only one tile), their range is also smaller than the Post Office. Another thing to keep in mind is that radiuses cannot overlap between each other: time to use those Tetris skills!

As the name suggest, only Local Mail will be consumed by your Residents on a specific island, while to obtain Regional and Overseas Mail, you will need to transport Mail via the Airmail Module and, therefore, Airships. In terms of numbers and percentages, about half of the Local Mail produced by your Residents will be needed to fulfil their Lifestyle need for local mail. This means that the remaining will be used to produce Regional and Overseas Mail.

Once you start producing enough Local Mail to get to second and third Mail tier, the next step is to transport it to other islands: this can be considered as the next step in the “production chain” of Regional and Overseas Mail. This distribution will start once you set a Trade Route through the Airmail Module. Once the Mail reaches its destination, it will convert to Regional Mail when reaching another island within the same session, or Overseas Mail when reaching another island in another session (except for Old World – Cape Trelawney, sending mail between them will only count as Regional Mail). We called this conversion process Route Alchemy. This does change a few things to how you are used to trade routes to work. First, mail will always be completely unloaded at target, it will not be unloaded in steps. If you cancel a trade route or throw the mail overboard, the mail will be unloaded and lost.

What about the Arctic, you might ask. Well, while the Arctic platform on the plateaus follows the same rules as when it was introduced back in 2019 with “The Passage” DLC, a special stand-alone mail module has been added for them with “Empires of the Skies”. For the regular islands in the Arctic, a modified Airship Platform has been added that also has this one module.

In short: You will still need to have a platform and a module on any Arctic island or plateau that you want to connect to your mail system. The existing Post Offices will now handle two tasks: Fulfilling the regular need of the Technicians and collecting as well as distributing mail in the context of DLC 11’s mail feature.

Drop Goods

Air-Drops are another important feature of the new Airships, allowing you to drop different goods on your islands, based on your needs. To produce them, you will need a Drop Goods Factory where you can choose your preferred good from the recipe list. Once produced, you can load the goods onto your airship.

There are 5 distinct types of drops available: pamphlets, care packages, bombs, sea mines and water. For each drop production, the Factory will require specific input goods but will use the same amount of workforce and have the same maintenance costs for each.

Pamphlet Printer

By dropping pamphlets on your opponents’ islands, you will create unrest, affecting residences and production by distracting your opponents’ population with propaganda.

Care Package Factory

An effective way to boost your own, your allies’ or neutral factions’ production and happiness! After all, who does not like a thoughtful care package dropping from the sky?

Water Drop Factory

When fires are too extended and firefighters are struggling to keep a fire under control, you will be able to take out fires with water drops from your airships.

Bomb Factory

As you have learned from our previous DevBlog, airships can now be armed with bombs and attack your opponents’ harbours and fleets.

Sea Mine Factory

An interesting way to sabotage your opponents’ trade routes and fleets would be dropping sea mines in the open sea.

Ornaments

Let’s not forget the most important part for the beauty-builders out there: ornaments! In total, there will be 8 brand new ornaments that will go perfectly with the whole DLC 11 theme. They will help you create the perfect atmosphere around your landing platforms and, of course, make your people feel comfortable and ready for their flights: a nice refreshing drink from the Airport Café, café tables to sit in the shadow, an airport clock to make sure not to miss their flight and much more!

Free Game Update: Military Changes

DLC 11 will also come with a free update, available for all the Anno 1800 players. We mentioned some of the changes already, like the resizing of the Passage Airships, for example, or the Lifestyle Needs and several new items. Alongside of those changes, there will be some free military improvements: for example, new weapons will be available for your harbours, such as an anti-armour gun or a flame tower. Following this, we did some changes to the different damage types, which means that based on the weapons you will build, there will also be distinct types of damage – e.g., wooden ships will take more damage from fire attacks from the flamer tower.

The full list of changes will as usual be shared close to the Game Update’s release – so watch this space to know more!

This brings us to the end of today’s DevBlog, Annoholics. We explored quite a few topics and had a taste of what awaits you in “Empire of the Skies” on September 20th. We hope you enjoyed the read and are ready for the next one, as soon we will share our third and last DevBlog dedicated to DLC 11: the “Clash of Couriers” Scenario DevBlog!

As usual, if you have any questions feel free to leave a comment below or reach out to us on Twitter, Facebook, and our official Forums.

Until next time, happy city-building!
