Only like three times have I played the dark side level where you defeat darth vader and I can't remember how I did it. Ran into a problem with my xbox and had to reformat loosing all my saved games and achievements.

Please can someone help me with how to defeat darth vader? He's harder then when I faced him in the previous 2 stages, which I don't know how since his suit would be manfunctioning, plus when she release his red energy ball he doesn't get tired. And why is is, when I get hit with lightning I can't move, but he doesn't effect him and takes like .00001% of his life O_o

Nevermind, I figured it out. Charging repulse when your close works!
