Control Anybody
Hold all four of the top buttons ("R1," "R2," "L1" and "L2") at any point during a single-player game. A secret menu will open. This menu shows you the non-playable characters currently in the game; select up to seven of them to make them playable characters. This is a handy method for improving the skill level of non-playable characters. Use the cheat to control them, train them up and then return them back to their computer-controlled states.
Special Officers
Select the ''New Officer'' option from the main menu and give your officer one of the names in this section to unlock a special officer. Make sure to enter the last name in the "First Name" box and first name in the "Last Name" box. Type "Julius Caesar," "Charles Darwin," "Albert Einstein," "Abe Lincoln," "Ben Franklin," "Sitting Bull," "Crazy Horse," "Harry Houdini," "Sun Tzu," "Wyatt Earp," "Mahatma Gandhi," "Norma Jean" and "Genghis Khan" to unlock one of these historical figures as officers. The character will have a generic face, but its skills and abilities will be extremely high when compared to standard officers.
Free Sword of Light
Create a new officer and set that person as a ruler, but don't assign him any followers. Sell everything you own and then withdraw your money. Since you have zero fame, zero deeds and barely any money, you will be given a free "Sword of Light." This is a powerful weapon that has a value of 20 and increases your war points by three when you're attacking.
Unlimited Fame Points
This cheat is a source of infinite fame points. When a new month starts, leave the game alone for roughly 10 minutes. A peasant will then ask you a question. For example, this may be "What city can you see the Great Wall of China in?" Look at the multiple choice answers and choose the city that you believe you can see the Great Wall of China from. If you were wrong the first time, reload the game and make another guess. Keep loading the game until you get the correct answer. Once you know the answer, continue to load the saved game and select the right answer. Every time you do this, you earn fame points that remain with you, even when you're loading a previous point in the game.
