Barbarians and technology, maybe they're not such a contradiction after all. It's the bow that nearly brought down Rome, and the suspension system that revolutionized the chariot. Barbarians built the forts that held out invaders, and forged the axe that named a country. We'll see inside the shop of one of the world's finest metal workers as he shapes iron ore into a classic Celtic sword. With 21st Century animation we'll rebuild a 2600 year-old hill fort--and show that protecting a village was as easy as digging a ditch. Finally, the designers of "Rome: Total War: Barbarian Invasion" reveal how they devised a system that accurately recreates the great barbarian battles. Which weapons scored best? The results may surprise you.
