Instructions
Use Obi-Wan to attack Jango as he runs around the boss stage. Press "B" to swing your lightsaber at him and attack, or hold "B" to reflect Jango's laser blasts back at him. When Jango only has seven health hearts left, he begins to fly around the stage, and the Slave I starts shooting at Obi-Wan.
Switch control to R4-P17 by pressing the "C" button. Move to one of the droid switches on the sides of the platforms, indicated by a small portrait of a droid and a colored target circle on the ground. Press the "B" button to activate a turret that shoots the spaceship piloted by Boba Fett and distracts it from firing on Obi-Wan.
Move control back to Obi-Wan and hold down the "B" button to reflect Jango's laser blasts back to him. Continue this until Jango has four hearts left and starts firing large missiles. (If Boba starts firing at you during this section, switch to R4-P17 and activate another switch, then switch back to Obi-Wan)
Press the "Z" button when the missile is surrounded by a colored field to use Obi-Wan's force ability to push Jango's missiles back into him. He will attempt to run when he has one heart left. Run to him and hit him with your lightsaber to defeat him, ending the level.
