How do you get through the final level on star wars the force unleashed

OK when you first get on to the level you are in a big room with lots of storm troopers everywhere and a few at-st's 2 to be precise if you first : go left and you will see a elevator go on it and then kill the snipers then jump down then you will see 4 or more metal grids on the floor open one just slightly then wait for an at-st or something to shoot a rocket at you the grid shield's you and blasts open, then jump inside that. you will be in a large cylinder like chamber the laser will fire at you (it's an instant kill so watch out!) you don't have to jump to the side at all just stay on the side of the screen until you come across a green glass thing break it jump in side and then break the other one on the other side and keep repeating that. LOOK AT YOUR MAP there's a passage way go in it throw a box at the opposing rocket launcher and kill the storm troopers. p.s. there will be some turret's in the laser tube but just throw something at them and they will go away. there will be a black and red door open it and then the game will save.open the other one and then you will see 2 spinning conductors after the laser fire's use the force and stop them, then 2 platforms will come out jump on them to the other side.(that was 1 conductor use the same tactic for the other) then go in a passage on your right go in it and there will be a GIGANTIC room jump to the bottom and push the giant battery into the machine and 2 tall blue elevators will come up jump in them and go to the top. when you see a big platform with a circular door jump on it and 4 red shadow guards + 1 black one, kill them open the door by forcing the handle one side to the other go in then you face dearth Vader kill him when you beat him he will go into a room with a laser on the floor just throw stuff at him till he's almost dead. when he says, *i will show you true Mastery over the dark side!* run over the sides and onto another platform kill him then you will go into the final room. You can choose the darkside or the lightside. I guess if you kill the emperor you will become a jedi if you kill Vader you will become a sith (I recommend the emperor because he's easier) and that's the very long guide!
