1. On the demo level when you first see the shield generator (Kyle will say "Well well the shield 
generator") do not kill the two stormtroopers so you can listen to their converation. 

2. (demo) When you fight the sith lord on padawan level you don't have to fight. 
Just hit him with your thermal detonaters 
(if you have any). 

3. (demo) If you don't have any thermal detonaters shoot the ground at his feet to shoot him without 
noticing. When he turns around shoot the shield generated wall behind him and he won't attack!
