umm nah dip Death Star!
After you defeat Darth Vader you will begin a battle with the emporor. Forget about that and go to kill Darth Vader. Swing at him with your lightsaber and the dark side ending will begin.
At the end of the game, depending on what ending you choose, you either kill Darth Vader, or the emperor kills you.
Darth Vader would win but just barely it would be an insane battle, but the force would tip the scales to Vader's favor.
Unless the Author brings along some alien artifacts, Darth Vader will kill him easily with the force.
cheat or kill Darth Vader 2 times on the death star Instead of running towards the emperor, jump down to the right
Darth Vader
no, he does not exist
That is a matter of opinion but I would say no, as Darth Vader can reflect energy blasts with his light saber, divert missiles and bombs with the force and of course; force choke her before she can get a move off.
Well, You enter a room after versing Darth Vader for time. It depends on who you want to fight Darth Vader or the emperor
He trained Starkiller to take out the remaining jedi. When Vader had no further use for him, he tried to kill him.
no, they will kill him >.>
No, he does not. Darth Vader's first apprentice (Galen Marek/Starkiller) is killed by Emperor Palpatine/Darth Sidious.
