Persians Featured in Rise of Nations: Thrones and Patriots Expansion Pack

"One of the most important buildings for each nation in Rise of Nations is the capital city. Once it's captured, you'll usually be faced with a time limit within which you must recapture it or build a new one--or else you lose. However, the Persians have two capital cities (the second city built automatically becomes a capital), which makes them especially resistant to defeat by the loss of a capital. The Persian forces are also bolstered by elephant troops that possess a powerful close-range attack--namely their tusks--which can plow through rows of pikemen. These already formidable beasts can be upgraded later in the game to mahouts, which carry gunmen that can fire from a distance. The Persians also possess powerful nonmilitary bonuses, like a starting bonus of 50 percent food, a discount of 30 percent on all civic research done to increase their abilities to expand, free taxation upgrades, and the ability to commission the maximum number of trade caravans available. Like all nations, the Persians also possess unique military units. The Persians may also commission immortals, a powerful type of infantry unit, and arquebus immortals, an upgraded version of the immortal that carries a firearm. "
