I think it could be done with a special boarding ship for the Romans: Corvus Quinquereme. It would come alongside the enemy ship and lower its Corvus onto it and slowly drain its loyalty. All other civs could have a late-game "Marines" tech to mildly counter this. Much like with capturing buildings, the more troops garrisoned aboard each ship affects the capturing rate (but never drops it to zero; we need to improve this with building capturing methinks). I think showing men jumping onto enemy ships and battling it out is not feasible. Not only that, but would add tedious micro and we want to reduce the size of ships for better pathing, so the scaling would be wrong. Best to just show a capturing bar or loyalty bar slowing draining down like we do with buildings. 

@zyliThanks for going all the way and test it. Your approach will work. Isn't the underlying problem that the scenarios in their current state are not compatible with any newer version of 0ad? This is why i suggested to port the scenarios,  itś seems like the more sustainable solution plus you get new features and fixes. @NewWorldHero have you already tried to port them and how many are there? What do you meant by somewhat modified? that is what i wanted to suggest, to use the migration scrips to port them.  The fact that your scenarios kept you on A23 (which was a great version) for so long got me curious. Could you maybe share them here?

I closed a few issues that were redundant or seemed to have been already done. I may do more later.

@NewWorldHero You've spurred me into action. I managed to install 0ad ver. 0.0.23.1 on Linux Mint Live 22.3 (still in beta). I figured there's no point in bothering with 22.2 since 22.3 will be released soon. 0ad is from Bullseye, and some dependencies are also from Bullseye, the rest from Mint – it works for now. If you're interested, post on the forum, but first read: https://wiki.debian.org/DontBreakDebian The whole thing – from start to finish. This also applies to other systems, including Mint. By installing 0.0.23.1, I turned Linux Mint into Frankenstein Mint, which, in my opinion, can only be done for fun or for testing purposes. Best regards  

@NewWorldHero I understand what you're writing as follows: I have Linux Mint 22.2. Why don't you tell me where the *deb 0ad file is in version 0.0.23? Of course, that would be the simplest. But it's IMPOSSIBLE. 0ad ver. 0.0.23 (0.0.23b, Debian 0.0.23.1) was released in May (December) 2018. https://releases.wildfiregames.com/ Linux Mint 22.2 was released in August 2025. https://pub.linuxmint.io/stable/22.2/ Linux Mint 22.2 is based on Ubuntu 24.04 LTS, Noble Numbat, released in April 2024. https://en.wikipedia.org/wiki/Ubuntu_version_history#Table_of_versions Six years passed between 2018 and 2024. Systems from 2024 no longer contain the package versions that 0ad 0.0.23 requires.  Such old packages (boost, icu, and whatever else) cannot be installed on new systems. Therefore, it can't be done. The only thing left is to find an older distribution for which this version was available and install it on a USB flash drive as if it were a hard drive. Ubuntu 22.04 LTS Jammy includes 0ad already in version 0.0.25b https://packages.ubuntu.com/jammy/0ad I found such a distribution for you – Debian Bullseye 11.11, which, moreover, still has the repositories enabled. Speaking of which, the Bullseye repositories won't be disabled until 2026-08-31. https://wiki.debian.org/DebianReleases You'll easily be able to install both the system and 0ad 0.0.23.1 on a USB flash drive before the repositories are disabled. After installing, keep the USB flash drive in a drawer, and when you want to play, you take it out, start your PC, and play. When you decide that's enough, you turn off your PC, disconnect the flash drive, put it back in the drawer, and then start your Mint. And you can go on like this forever. Well, maybe not that long – until you replace your PC with one that Bullseye can't handle. Happy New Year!
