I installed Alpha 28 on my computer and it launched, but then no action was recognized; even just clicking on "OK" in the intro menu had no result.
I tried both through the Snap and through the Backports of Debian Trixie, both had same results.
I played Rus on a26 and the Hunting Lodge wasn't available to build, so I didn't have a way to research Rogatina and get Hunters...
Same for the other military unit, it required Embassies but there was no way to build those.
Also, the Rus don't have a Wonder ? Is that on purpose ?
Not sure about armour (arrows can be designed specifically to work against chainmail, but afaik not against plate) but shields are good against pierce - which is another way to make units differents.
These two posts from Devereaux illustrate well how the game should make missile work, imho.

Even for one civilization, I really don't understand the difference between most units...
I get the difference between melee and missile of course, between cavalry and infantry, between spearmen (good again cavalry) and swordsmen (good again siege units), but that's basically all...
But what would be the UI/UX of it ?
It's quite visible in land fights when troops are trying to capture a building, how do you want to do it in naval warfare ? Where the garrison isn't visible on the map ?
