How do you beat Darth Vader for Star Wars the force unleashed 2 for the Nintendo DS

first get to him them just keep side slashing him for the first part then he will smash down some stuff use force push blow them back then when there on the ground slash side,side,down that should make them fly in the air jump up and down slash them this should do lots of damage keep doing this all the way. next at the end youl go on the roof and you have to Battle him this is the hard part set force push just run at him and side slash him but after ever 2-3 tap him so you will shoot him that makes him not shoot his ******blast at you it won't hurt him but it stops him the faster the slashes the better don't move so much just kill him next he will go into a face to face light saber battle just tap like crazy. make sure you tap to mush because then your force bar gos down to fast after you beat him you can choose to kill him or put him in jail the first time i did it i put him in jail but the second time if you slash him there's a cut seen just before you kill him it shoos his face ...STAB you get killed be the real star killer bye.
