The Parthians have joined the growing list of playable factions in Total War: Rome 2. Set in classical antiquity, the game will see players partake in the rise and fall of the Roman Empire as kingdoms vie for dominance over the ancient world.
"A confederation of tribes, Parthia is famed for its horses, nomadic horse-archers and heavy cavalry, the latter developing distinctive bronze or iron scaled armour which covers both horse and rider. For its infantry it relies on ethnic Persian/Iranian hillmen, spear and skirmisher units and sometimes mercenaries, armed and drilled in the Seleucid fashion."
The Parthians are said to practice Zoroastrianism, which forbids slavery and while that allows them to better integrate with other cultures, it also means they are unable to control their populace as efficiently as other more pragmatic societies.
You can read further details about the Parthians on the official wiki.
Total War: Rome 2 is currently in development at Creative Assembly and is scheduled for release on the PC this October.
