Star Wars: The Force Unleashed

You'll encounter Luke twice in the Hoth base and have three fights with him. The first time, use your Force Lightning a lot. Strike him with your lightsaber while he's stunned. Aerial attacks also work well against Luke. After you beat him, he'll take off running through the base. You'll meet him again in the Hangar. For this second fight with him, use the same strategy of Force Lightning to stun, then strike . This time though, he'll have Rebel troops around that will shoot at you while he's attacking. After you beat him again, Luke makes a comeback and you have to wear down his life again. Use the same Force Lightning to stun, then strike strategy. Luke is a little cheap this time and will use more Force powers.
