Natus ob Imperium is a global mod focused on antiquity. In fact it's an independent, unique game based on the MTW2K engine. The game has plenty of unique features such as exclusive graphics (which takes into account the specifics of the warriors and geography) and original gameplay.
Now I don´t know what do you mean by an "early" Centurion. The centurio´s started to be used after the Marius reform. The armor also looks for at least the second half of the second century (brestplate).
Wrong, centurion already existed during polybian or camilian reforme.
Oops, silly old me, ofcourse centurions were used before Marius, Im sorry for that, I just gol a little bit confused. I still however find my criticism of the breastplate valid.
Excellent!
