Pause the game, select "Quit", set the CPU to control your officer, then quickly hold L1 + L2 + R1 + R2 + Select. A window allowing one of up to other eight officers to control will appear.
Play as Lu Bu
To get Lu Bu, fight Dong Zhou during the Dong Zhou story in an all out war when you move your own people. Take all your men and go straight for Lu Bu as soon as you find him. Once defeated, take the officer that has him to a very safe place and finish the rest of the level. Make sure to have powerful people by starting from the beginning, as Lu Bu has 108 war ability. Be sure to take Lu Bu quickly so there will be a better chance of getting him, and you do not have to execute him. Note: Sometimes Diao Chan will appear. Take her after defeating Lu Bu.
Secret Characters
At the main menu, select "New Officer". Choose "Create New Officer" from the new officer menu. Choose the name option and enter one of the following names. For example, for Abraham Lincoln, enter Lincoln as the last name and Abraham as the first name, so the name appears as Abraham Lincoln. A musical note will play, and an officer will automatically be created and given type, ability, skills, and gender. Select a birthdate, and face and everything else is done.
