Keep lightsaber:
After you complete the game (Light or Dark side), you will see the credits. During 
the credits press Y, X, B. If you hear a lightsaber ignite, you have done this 
correctly and you have unlocked the lightsaber that you ended with for a new 
game. For example, if you end the game with a saberstaff and execute the code, 
you will be able to use that exact saberstaff when you begin a new game.

Defeating Allora:
When you are on Hoth at the room before you get to Allora, you will see a Wampa 
attacking a Tauntaun. Save the Tauntaun from dying and ride it into the room with 
Allora. When the battle starts, immediately ram the Tauntaun into Allora. It will be 
an instant kill.

Defeating Rancors:
In the mission where you save the elders from the Hutts, you can easily kill the 
Rancor by drawing it to the main door, where the prisoners escape though but the 
Rancor can not fit into. Stand back so that it cannot swipe at you with its arm and 
throw your lightsaber. It will take a few hits before you kill it. Try holding L as it 
keeps the lightsaber on him for a while. This is completely useless during the stage 
for rescuing the prisoners as another Rancor appears, but you at least get the 
satisfaction of killing it.

Defeating Reborns:
Activate Force Speed (works best with grade 3 speed) and slash once at their front 
to lure them down. Then, run around behind them and slash their back as many 
times as possible. This works best if you push them in a corner and complete the 
procedure. 

Use the following trick to kill Reborns, Reborn Masters, Jedi, and other Force users. 
Use Force Grip to hold them in the air, then throw your lightsaber at them to kill 
them. It is harder to do to some, but if you timed correctly you will hit them. This 
usually works best with Grip level 3 and Saber Throw level 3, but is still possible to 
do with the other levels.

When fighting the Reborns at the start of Chandrilla (after the bridge is blown up), 
lure them all to the bridge then jump over to the other side. Two of the Reborns 
will attempt to jump over as well, but will fall to their doom.

Defeating Wampas:
To kill a Wampa quickly, let it grab you. As you are hanging upside down, swing 
your lightsaber to cut off its arm and kill it instantly.

Get into a walker:
When you get to the Cult At Dousm level, work your way though until you reach to 
the walker hanger. Once you are inside, open the big door with the control beside 
it. Then kill the man in the room inside the hanger. Turn on the lift in the hanger, 
then hop out of the room and go up the lift. Up there, you will see three walkers. 
Hop on one, then look down and press Y . Now you have the choice of the side 
cannon or the main weapon by cycling through the weapons. Press Y to exit. 

Instant kill:
While fighting an enemy, run towards them and press the Right Analog-stick to 
roll. While rolling, tap Attack as many times as possible and you should stab 
forward. If done correctly, this should instantly kill your opponent. If done wrong 
or if you did not put the lightsaber far enough into the opponent, sparks will come 
out of the tip. This will work for any enemy. 

Easy kills during bot matches:
This trick works best with either double-bladed or dual lightsabers. Get involved in 
a multiple person duel. Use you super attack by holding your primary and 
secondary attack (L + R). The bots are too heavily involved in their other battle to 
fight back. As soon as you kill one of them, rapidly attack the other. Try to push it 
into a wall. This will help greatly with your kills to win.

If you are on the Dark side, grab them with Force Grip and put them over an edge 
then drop them. If it is endless drop, they will be killed. If it is a long drop, it hurts 
them badly. To insure that no one else kills them with your work, jump down and 
use Force Lightning while looking down at them. They should die before you reach 
them. If not. rapidly attack them with both saber and Force power.

With a single blade, attack them rapidly into a wall then use Force Lightning. While 
they are being shocked, use and hold Secondary Attack and they should die 
quickly.

Keep previous weapon:
Successfully complete the game on the Light side and Dark side storyline. After 
completing the game for the second time, start a new game in the same session 
and you will begin with the last type of lightsaber used. 

Third person view with blaster rifle: 
Go to the Hoth level and get on to a Taun Taun. Switch to a blaster rifle, then get 
off to be in third person view. Note: Do not switch weapons or the third person 
view will be gone; also do not kill the Taun Taun.
