[edit] System requirements

In order to play Civilization IV on Windows, your system must meet or exceed the following requirements[5]:

[edit] Civilizations

[edit] Cheats

[edit] World editor

Unavailable in the unpatched version, the world editor is accessible in game in the menu (press [esc] to open the menu during the game). It allows you to edit anything on the map, like placing using, buildings, resources, etc, and also unlocking technologies. Although very powerful and easy, this way of cheating has 2 major drawbacks:

  1. It reveals the map - so no more surprise about where the enemy is and where the hidden resources are
  2. It's not a good idea to unlock certain technologies using this method, for instance unlocking a technology that makes its first creator found a religion with the map editor won't make you found the religion.

[edit] Cheat codes

[edit] Enabling the debug mode and opening the console

To use the cheat codes, you first need to enable the console. To so, you need to edit CivilizationIV.ini, located in the folder My Documents\My Games\Civilization 4 (NB: a shortcut to this file is also available in the directory where you installed Civilization IV). In this file, find the line CheatCode = 0 and replace it with CheatCode = chipotle. Now, during the game, you'll be able to use the debug keys and to open the console with the [~] key.

[edit] Debug keys

Most of the debug keys will behave differently depending on what you have selected:

[edit] Code list

In the console, you can use the following case-insensitive codes (only a few are interesting for cheating):

[edit] XML files editing

A lot of things cheat effect can be achieved by editing some game files. This method of cheating can be particularly interesting as it acts more as a difficulty modifier than as a "real" cheat. For this chapter, we will be modifying Warlords XML files. For the unexpanded version of the game, the file structure should be pretty close (but not entirely the same), the main difference being that some buildings/units/traits exist only in Warlords. During all this chapter, we will refer to the folder [your game folder]/Warlords/Assests/XML (or [your game folder]/Assests/XML for those who don't have the Warlords expansion, or who have it but want to play the unexpanded version) as the XML folder. The game will fail to load if there is the slightest error in the XML files, so you'll want to back up each file before you edit it. A simple way to back up your files is to copy/paste any file before you edit it (and leave the copy in the same folder as the original).

[edit] Changing/adding traits to a leader

Open the file XML/Civilizations/CIV4LeaderHeadInfos.xml. For every leader, it contains a structure like:

        <Type>[code name of the leader - for instance Isabella of Spain is "LEADER_ISABELLA")</Type>
        [... Many attributes here ...]
                        <TraitType>[a trait code - for instance "TRAIT_SPIRITUAL"]</TraitType>
                [... The second trait ...]
        [... Many other attributes there ...]

You can change a leader's traits, or even add them more traits (there is no limit to the amount of traits), by editing/adding a <Trait block>. All traits can be found in the XML/Civilizations/CIV4TraitInfos.xml file. For the lazy, here is the list of available trait codes in Civilization IV Warlords:

Added in Warlords:

Note that when modifying the traits of a leader, the change will apply to you and to computer-controlled players as well. So if you make a leader with 6 traits, you'll probably want to be the one controlling it and not give it to the AI!

[edit] Creating a new trait

If you want to boost your leader, creating a new trait may be a wiser choice than boosting an existing one, as boosting an existing trait will boost any leader with this trait, ie, potentially an AI opponent.
Open the file XML/Civilizations/CIV4TraitInfos.xml. It contains most information about all traits. To add a new trait, the only thing you need to do is copy any TraitInfo block, paste it just before </TraitInfos>, and change its ID (the info in the Type block). Of course this only duplicates an existing trait, to make a base to a brand new one, ready to be edited. Here is an example trait, giving a lot of bonuses (NB: this wil probably crash the game without the Warlords expansion, as it contains an unknown field about the Great General, a unit introduced in Warlords):


Note that for this trait to work, you'll also need to edit XML/Text/CIV4GameText_Warlords.xml and add, before </Civ4GameText>:


(this adds a description for the trait)
This trait gives, among other things: a +3 health and happiness bonus in every city, 7 gold + 20 research + 10 culture in every city, no anarchy (from changing civics or religion), civic upkeep reduced by 90%, XP needed for unit promotion reduced by 90%, +250% great person rate, +250% great general rate, +250% great general rate within cultural borders, +200% world Wonder production. It also gives bonuses for the production of various buildings and units, but these are set in two other files:


[edit] Removing city maintenance costs

Open XML/GameInfo/CIV4HandicapInfo.xml. Each difficulty level has its settings stored with a HandicapInfo block. Find the block of the difficulty level you want to edit (for instance, noble starts with <Type>HANDICAP_NOBLE</Type>), then find their iDistanceMaintenancePercent and iNumCitiesMaintenancePercent blocks. They configure, respectively, maintenance cost from distance to palace and from the number of cities. For instance, for 75% maintenance cost from distance and no cost from number of cities, you'd write:
