Animal version of Tsentom's Crusade.
Spawns a random animal with strength = (base strength + 3) * current era, where ancient era = 0, future era = 6.
(You know, with advanced technology, you understand them better and feed them food with more nutrients)
A future era bear will have 36 strength, lion 30 strength. Looks high, but they don't get defensive bonus.
Because they are animals, they cannot enter cultural borders, as a result: they are stuck in the city, since all adjacent tiles are cultural tiles. Makes sense to keep them in the biodome. We don't want lions roaming around eating workers. Thus, purpose of them is defend the biodome city. Since they cannot enter adjacent tiles, they cannot attack anything, so they are your holy defenders
Bears are so huge, they can flatten tanks => Ambush promotion
Lions roar very loudly, horses are scared => Formation promotion
Panthers are so dark, they ambush you in the dark without notice => Drill I
Wolves attack in packs and are agile => Immune to first strike => Flanking II
If the city has enough unit production experience, the animals get additional promotions when born.
For instance, barracks give 3 exp, enough to level up once, so animals get Combat I.
Able to get Combat I to VI this way.
Animals do get experience in combat, but because nothing is added to them in Promotion XML, they cannot earn any Promotions, feel free to change that if you like.
Lastly, I didn't bother to test whether you can transport them via air or sea lol
Artwork by Hrochland, tried getting a button of biodome itself but it just doesn't fit into a square nicely, so end up taking a pic of lion
Yeah, you know how bored I am now
Oh yeah, this is a National Wonder
