does anyone know how to create a unit??? i want to create a barbarian unit that has no movement and 3 strength. this will help with setting down barbarian cities in a custom map. thanks.

There are a lot of guides in the Creation & Customization folder that deal with creating new units. As far as sort of replicating an existing unit, you could copy Warrior's XML, repaste it(so you have two Warriors), then add 1 strength and take away the movement.
