Adds a number of new units such as Lorica Segmentata armoured Legions, Gothic Grey Horses, Gallic Warbands.. All fully compatible w the vanilla game.
Unfortunately it does NOT work with the vanilla game.
However, some of the added units are compatible. So with a few edits it is possible to get some value out of it. This mod greatly helped me to understand how modding works for this game, so I gave 3 points instead of just 1.
