As such, spies are not available until the Renaissance era. The espionage system is designed to take effect just as the religion system begins to taper off. Captured spies can also reveal information to the opposing civilization. Additionally, unlike in past games, spies can gain levels by successfully performing a mission, just as combat units gain experience whenever they engage in a battle and succeed. Instead, they are awarded at certain intervals along the timeline. Unlike in previous games, however, spies are not trained by a civilization. Spies are capable of stealing technology, rigging elections, performing reconnaissance, as well as various other espionage missions available in previous Civilization games. Įspionage in Gods & Kings can be used to invade rival civilizations as well as city-states. However, the player has the option to rename a religion as they wish. Gods & Kings includes eleven religions: Buddhism, Christianity, Confucianism, Hinduism, Islam, Judaism, Shinto, Sikhism, Taoism, Tengrism and Zoroastrianism. Religion will feature prominently in the first two-thirds of the game, affecting diplomacy and international relations, but its effect will taper off as players approach the modern era. The use of Great Prophet, missionary, and inquisitor units also allows players to spread and control their chosen religion.
Players are able to found a religion and customize its various beliefs, resulting in differing in-game benefits, through the cultivation of a "faith" resource similar to how culture and science already function in the game. Gods & Kings reintroduces a religion mechanic to the series. Three new scenarios are included in the expansion: "Fall of Rome", focusing on the decline of the Roman Empire "Into the Renaissance", focusing on religion in the Middle Ages into the Renaissance era and "Empires of the Smoky Skies", a Victorian steampunk scenario. Gods & Kings adds an additional 52 Steam achievements to Civilization V. Additionally, the combat system has been re-worked to include smarter AI, an expanded early modern era, and enhanced naval combat featuring Great Admiral and melee naval units. City-states also feature a new quest system and strategic importance. A new religion mechanic featuring a " faith" resource allows players to found their own religion which they can grow into a "world-spanning fully customized religion." Diplomacy has been reworked to include espionage, foreign embassies, and new types of city-states (religious and mercantile). Gods & Kings includes 27 new units, 13 new buildings, nine new wonders, two new eras, and nine new playable civilizations.
