press start at the allies screen with the 2nd controller

The only way to do this from the beginning is to start as a ruler, otherwise you must get
asked to be a friend first.

1. You start off with, lets say you created a player named John in edit mode. You select
him and you are a ronin (vagrant officer with no home) that travel's doing missions for
villagers and selected Officers such as Guan Yu or Lu Bu
2. Go to the "Battle" button and press "X" when you highlight it.
3. Then press the "Mercenary" button.
4. Look at the rectangle description box and look at the "From" section.
5. Let say your friend made a character called Mike, then you find the Mike character
beside the "From" part of the description box.
6. Then you start the mission, rescue your allies and innocents and then go into the
strategy mode and go to events there should be a flashy "New!" beside the "Events"
Buttons.
7. Afterwards an option that says become friends with "Mike" then you are his friend, then
after that you start a fight/war with someone then the 2P should press the "START" button.

8. Thats about it.

From Mr.Amazing.

you should name your created character John Franks, and the other guy Michael. PS. Thats
about it?
