Now is the time to contribute!

The Release 28 is our first release without the Alpha label: our development process has matured, our releases are more frequent, and our commitment to quality has never been higher. Now is the time to join us and place 0 A.D. in the spotlight. We need your help to make the game flourish and to bring new features to life.

As you can see, this release unfortunately comes without a video trailer. It is difficult for the current team to spread the word about our beloved game. We are in sore need of contributors in the following areas:

• Video Editing
• Social Media Management
• Website Design

Of course, we are also always looking for, and providing a welcoming contribution environment, for:

• Testers and Quality Assurance enthusiasts
• Translators (get started right away on Transifex)
• and of course, Developers and Artists - the team will gladly welcome contributions in all areas.

You can also support us by simply donating. This allows us to pay the server hosting fees for our multiplayer, websites, and development environments.

A new faction: the Germans

Terror Germanicus, the fear of the Germanic tribes migrating south, from the Jutland region, towards the Roman Republic, is coming to 0 A.D. in Release 28.

The Cimbri were a large group of Germanic peoples originally from the north of modern-day Denmark. In the late 2nd century BC, their migration south into Italy and France would spark the decade-long Cimbrian War against the Roman Republic. Accompanied by powerful armies and seeresses, Germanic convoys, in long trains of wagons, brought livestock, shelter and goods. The Cimbri placed great importance on animals for religious sacrifices.

In 0 A.D., we represent the nomadic coalition formed between the Cimbri, the Teutones, the Ambrones, and other Celto-German tribes simply as the "Germans". The Germans are a semi-nomadic civilization with a flexible economy owing to Supply Wagons and Wagon Encampments, which can be fortified. The unique technologies "Wagon Trains" and "Migratory Resettlement" lean into this flexibility, reducing dependence on territorial boundaries. The Germans also feature an aggressive lineup of siege units, with a crush-dealing unit available in each phase. Between their economic flexibility and unique military units, Cimbrian raiders, Log Rams, and Seeresses, the Germans are a mysterious force to be reckoned with.

Play with this new faction, against their historical Roman foes, or turn history around by making them battle the 14 other factions of the game. Many other novelties await you in the new release of 0 A.D.!

Top new features of Release 28

• Gendered Civilians
• Direct Font Rendering
• Support for JavaScript Modules
• New Game-Setup Options
• Lobby improvements
• Engine upgrades and updated platform support
• New quotes and tips
• Various balancing improvements
• ... and much more!

Gendered Civilians

In an effort to improve historical consistency, we have replaced the visual appearance of civilian units. Previously described as a "female citizen", the basic economic unit is now called the "civilian" and has male and female models.

This enhancement was made possible by incremental improvements of the engine, which now allows a unit to have variants not only in its appearance, but also in its voice and in other gendered characteristics.

In the civilizations displayed in the game, women did not usually hold citizenship, which was a prized social status. The "female citizen" was a misnomer. It was also incorrect to display all men as soldiers, and most women as servants. Instead, we want to describe the armies of 0 A.D. as followed by a group of minions of lower social status, able to support the soldiers in the army camp, but not on the battlefield. Those are the new Civilians. Citizens, on the other hand, were soldiers, able to wage war as well as working, which we have always been accurately describing in the game with the citizen-soldier concept. The ambiguity of the term "citizen" is removed: this word now only describes citizen soldiers.

This change does not touch the balance of the game at all. The so-called "female citizens" keep all their statistics, only their appearance and name have changed. The citizen soldiers are not touched at all.

Direct Font Rendering

In order to display text, we used to pre-render fonts and load them into memory when starting the game. In order to display scripts such as Chinese, we needed to load a large atlas of thousands of characters into memory, which could overwhelm the players' RAM. As a consequence, we were forced to provide East Asian languages as mods, which was an accessibility issue for non-English speaking users of these languages.

On top of memory management improvements, we now use the Freetype library in the engine to render fonts on the fly when the game runs. Modding the fonts also becomes far easier with this new feature.

This new rendering system also improves the text display with GUI scaling, for users with Hi-DPI screens or who simply wish to use a larger interface.

In the future, we hope to also use this feature to render ancient scripts, such as hieroglyphs and cuneiform.

New Game-Setup Options

New personalization options are available in the game setup screen.

You can remove some players entirely (removing all of the initial buildings and units in their starting zone) in Skirmish and Scenario games.

It is also possible to set the population limit per team:

Lastly, some code refactoring allowed us to fix outstanding bugs in the game setup. For instance, in Alpha 27, a recurring issue would create an unwanted flood event in games where the user had previously played a flood game. This issue has been fixed.

Lobby improvements

The multiplayer lobby received some quality of life improvements. Verifying TLS certificates is now enabled by default when connecting to the multiplayer lobby, reducing the risk of man-in-the-middle attacks. A secure connection to the lobby will become mandatory in future releases, so please check that TLS encryption and certificate verification are not disabled in your settings, and report any issue you may encounter.

It is also more straightforward now to host matches, as there is no need to decide whether to use STUN or not; and a bug causing freezes when joining a match got fixed.

We have decided to rename the main menu entry for playing with friends over LAN or by direct IP: now called Multiplayer > Connect by IP, it is still the same system for direct matchmaking without using the lobby.

Engine upgrades and updated platform support

In Release 28, we have upgraded the SpiderMonkey JavaScript engine to version 128. This upgrade drops support for Windows 7 and 8.1, and for macOS below 10.15. Windows 10 and 11 are now the only supported Windows versions, and we will try our best to keep supporting Windows 10 as long as possible.

Still on Windows, we now provide a long-awaited 64-bit build, which should address infrequent out-of-memory errors. The 64-bit version will become the default one for the next release, and the 32-bit build will eventually be deprecated in the future.

On Linux distributions, special care is always given to release bundles for package maintainers, but we also walked the extra mile to provide an AppImage in official releases, starting with Release 28. We are also working close together with maintainers of the Snap and Flatpak versions, so that you can enjoy the latest release as soon as we get it out.

So, for us modders, all that we'll need to update is the stuff that calls upon FemaleCitizens, replacing them with just Citizens? What else is needed to work on R28?

[strat0spheric]

THANK YOU ALL DEVELOPERS !!!! 

You are doing a great job to satisfy the unfortunately small community, which makes your efforts even more exceptional.

I love you

keep up the good work!

Oof, siege buildings are now purposeful. Congrats.

As hidden in the announcement, there's a mod porting guide on the Wiki (especially for the programming side of things):

cool, glad to finally have the next version to play  

Alas there is already a problem to report, The Roman Fertility bonus is no longer functional, they still have to research fertility festival now to get civilians from houses. Is that due to the change in keywording or was the civ bonus just outright removed?

I checked it out, but it only lists a few of the changes that need to be made, I’ve already encountered three or four unlisted ones.

Can you tell me which? It's supposed to be complete, but it might not have been updated consistently enough.

[Perzival12]

First of all, SinkProb was added into the templates (in Decay, in both template_unit and template_structure).
Second, world_population_capacity was merged into population_capacity. This also means that settings.js in guy/common needs edited.
Third, backgrounds.js was added into the backgrounds folder, and needs to be added back in if anyone has a backgrounds.DELETED file. It also needs edited to fit their custom backgrounds.
Fourth, ProjectInformation and MainMenuItems have some changes regarding whether they use var g_blablabla to export const blablabla.
I'm sure there's more, but that's what I've found so far.

[Perzival12]

Also, I think there is a bug in the MP rating system, look at these screenshots:
