This is why I'm asking when the AI changed, because zombies in my game have completely different behavious to all the other monsters.
They work like that since forever, as Juku pointed out.
I know how to build them - I'm just raising the point to the modder that it's not very obvious to the player what's going on when the research for Tank/Scout is done and you can buy the ammo, but there's potentially no way to build one.
I've researched Alenium Awakening, which gives you info on Tank/Scout and the ability to buy ammo for it, but no way to buy or make one. I understand this is dependent on Advanced Robotics, but maybe Tank/Scout and the ammo should be kept hidden until Advanced Robotics is reseached?
Tank/scouts don't need adv. robotics, you can get "AI Unit" with just "Alenium shard awakening". As mentioned, they need workshop to manufacture. That being said, adding "Requires workshop to build" to either or both "AI Unit"/"Alenium shard awakening"
pedia would be nice.
Guarding "AI Unit" behind "Workshop" would be nice too. For that, I guess "Alenium awk" unlocking needs to be removed, and "Adv. robotics" dependency needs to be changed to "Workshop".
