I've recently been looking back at Rome with the intention of trying out a different faction. I was considering Carthage as they have an interesting and varied unit roster, with the scared band holding a particular allure. However, looking at the building browser I can't see how you gain access to them. Are they not available in the single player campaign or is there some sort of event akin to the Marian reforms that allows them to be built later in the game?
Can anyone help? Perhaps I'm simply being blind!
