Instructions
Select a Saiyan from the list of available fighters. The available Saiyans are: Goku, Kid Gohan, Teen Gohan, Vegeta, Broly, and Bardock.
Begin fighting and attack your opponent until your Kai Gauge is full.
Press the "RB" button (Xbox) or the "R1" button (PlayStation) once your Kai Gauge is full, and you will transform. Depending on the Saiyan you select, you will either become a Super Saiyan or transform into a form below Super Saiyan. For example, Goku will not become a Super Saiyan after the first transformation; he will undergo a Kaio Ken transformation.
Repeat steps two and three until you become a Super Saiyan, if you do not become one the first time.
