In the level "Discovery on Kamino" when you come out of Jango's room, there are two turrets shooting at you. you can be any jedi or sith character and it is easiest if you have invincibility. Stand as close to the force field as possible and destroy the turrets. If you are quick enough you can get close enough to Jango to use the force on him. If you do this quick enough, you can kill him. He does appear again later in the level but it is funny how you can kill him earlier.
