I remember seeing this documentary on the plague, with this thing that Mongols used biological warfare in order to weaken cities.
Maybe for Mongolia?
Edit: No Mongolia. Maybe for the huns then
Possible, but seems hard to implement. Perhaps a unit that decreases health of adjacent cities, even when it is not attacking?
Not sure you would suit best (Assyrians but as their not in, maybe Babylon?)
Seige Tower:
Weaker than catapult and range of one, but no iron requirement.
Start with Cover promotion, and can stack with one melee unit (to protect them from city range attacks)
Every time the unit is wounded but surrounded, it deals damage?
Wheel sounds good as a tech, not sure for it's upgrade though. I was seeing it as an alternative siege weapon if you weren't lucky enough to get iron...
Suppose Trebuchet will have to do, and just hope you've conquered somewhere with iron with the towers!
forgive me if I'm wrong, but weren't eagles generally armed with spears?One I thought of for the aztecs:
Eagle:
Replaces Longswordman, same strength. Unique promotion, upon killing an enemy unit the Eagle gains a 2% combat strength modifier for future battles, up to some maximum (15?)
A big part of an Aztec warrior's standing in their culture was how many slaves they had captured in battle, who could then be sacrificed so the Gods may favour the Aztecs.
It would also provide good synergy with the jaguar, any you manage to upgrade to Eagles will be a very scary unit!
I was making them Longswordmen just for the synergy with the jaguar. Another idea I had was that on killing a unit, there was a % chance it would increase pop in one of your cities, though I didn't think it would be that useful.
Here are some ideas
France
UB: Salon. +1+1
. Bonuses doubled if Liberty, Rationalism, or Freedom social trees are complete. Tripled if all three are complete. Becomes available with Printing Press. Represents France's contribution to the Enlightenment.
Russia
UU: T-34 Tank. attack bonus vs. other tanks. Defensive bonus against land units. Gives Russia a more modern unit to use. One of the most recognizable and effective WWII tanks.
Babylon
UB: Code of Law Stele. Acts as a cheaper courthouse but takes turns to fully pacify an occupied city. In non-occupied cities +1 Happiness and +1 Gold. Becomes available with writing.
