Civilization IV: Beyond the Sword

Corporations become available with discovery of the Corporation technology. Each of the seven available Corporations requires a particular type of Great Person, a particular additional technology, and access to particular resources to build the Corporate Headquarters and found that Corporation; each of the seven Corporations can be founded only once per game. Each Corporation consumes specific resources, and supplies alternative resources or benefits in return. The more instances of resources they consume, the more food, production, commerce, or resources they supply. Corporations can be spread like religions (using the Executive unit as a missionary) to other cities, including foreign cities; any city hosting a Corporation branch must pay a maintenance fee for its services, while the owner of the Corporate Headquarters receives bonus gold for each branch. Players can block foreign corporations from operating in their cities by adopting the Mercantilism civic, and they can block all corporations, even their own, by adopting the State Property civic.

Espionage's importance in Civilization IV has been raised to compare with that of scientific research, culture, income from taxes etc. The new espionage slider allows the player to divert part of their income towards espionage activities against other civilizations. Once the player has reached certain thresholds of espionage investment, the player starts gaining some automatic intelligence benefits over rival civilizations. The player can also send Spy units into foreign territory to gather further intelligence and to perform various missions of destruction and propaganda. Their role is a bit different, because spies are now invisible to all units, save for other spies.[6] Great Spies are born in cities, like other Great Persons, and can perform typical functions like serving as a Specialist, starting a Golden Age, or building a unique building. Their special function allows them to infiltrate enemy cities, giving the player significant advantage in espionage against that civilization. Just like other Great Persons, they have unique names, and their appearance changes accordingly to the time period, e.g., a Great Spy in the ancient era shows up as a ninja, just as the Industrial-Age Great Spy appears as a tuxedo-sporting James Bond-style unit, complete with similar thematic music once a mission is performed.[7] Conversely, espionage has become somewhat of a hindrance in the pursuit of normal diplomatic victories. The act of catching opposing AI controlled spies will devastate your diplomatic relations with those players forcing you into a negative relationship that you cannot recover from. Even a friendly AI could potentially have a hidden −10 points from captured spies that will never allow a diplomatic victory, even through rampant generosity of resources, technology, gold, and all other attempts to negate the immense negative statistic. (This can be tested by saving an in-progress player vs CPU game and continuing it with players in place of the AI.)

The expansion reintroduces SimCity- and Alpha Centauri-style random events from the original Civilization game, which can cause the game to swing in the player's favor or present another obstacle the player must overcome. There are more than a hundred of these events, including natural disasters, such as earthquakes that can destroy buildings, and diplomatic marriages that might suddenly turn two former rivals into friends. Together these new events give each game a completely unique flavor.[8] In addition, each game offers players the opportunity for rewards through the completion of special events in the form of missions ("quests").[9]

Some examples of Random Events in the game include tsunamis,[10] floods,[10] discovery of new resources,[10] earthquakes,[11] diplomatic marriages,[10] pleas for help from other civilizations,[10] and unexpected demands from citizens.[10]

Advanced Starts are a pre-game setup phase players use to purchase cities, improvements, buildings, technologies, and units. It works in both single-player and multi-player. The player decides what to purchase and where to place it. When everyone is done, the game starts with players controlling relatively balanced, advanced empires with a working infrastructure. This mechanism is ideal for those who want to jump right in and experience a balanced game in a later era, without having to start it from the Stone Age. However, if Advanced Starts are used, players cannot declare war for the first 10 turns of the game.

To acquire a Space Victory, the game now requires the player's spaceship to reach Alpha Centauri, rather than simply launch. It is now also possible to build spaceships that fly faster than those of other civilizations, so that a player can achieve Space Victory, even if they finished building a spaceship after a competitor.

The new Apostolic Palace wonder allows the player to win an early diplomatic victory, centuries before the United Nations is due to make its appearance. The wonder is tied to the state religion of the player who built it. Depending on the influence of the Palace's religion on their civilization, players get votes to cast on decrees like holy wars, trade embargoes, or peace enforcement. It is later rebuffed by Communism and made obsolete by Mass Media. At this point, the more modern United Nations takes over many of its functions.[12]

The expansion offers various new world-types and game options. The player will have the option to play as any leader-civilization combination, therefore allowing "what-if" possibilities. Also, a new feature is the option to only trade away player researched technologies. Finally players can optionally choose any religion once they have founded one of the specific religion-founding technologies, so that the same religions will not be dominant in every game.[13]

The title screen depicts the Santa Maria del Fiore of Florence, but it is not visible in the game.

New content includes:

• Ten new civilizations and leaders (Babylonia, Byzantine Empire, Ethiopian Empire, Holy Roman Empire, Khmer Empire, the Mayans, Native Americans, Netherlands, Portugal and Sumer)
