Due to the relatively small number of battle replays for Barbarian Invasion, I have decided to submit one that shows the effectiveness of the iron darts of the Plumbatarii. I believe that those darts are the only reason I managed to win this battle.
The battle begins with a small missle duel. Following this, I advance. Once the battle lines draw close, the dart storm begins. By the end of it, almost all of the units in Aquila's front line are very heavily damaged. Then the Lombard Berserkers charge. I move my cavalry around to deal with his cavalry. We engage. After his cavarly comes close to routing mine, my Plumbatarii finish off his Berserkers and run to the aid of my cavalry. That pretty much ends the battle.
I think the reason for the small number of replays for this amateur mod is because the replays are not accurate therefore the product you spent your money on is defective.
