At the multi-player character selection screen, set the Force level on Jedi Master. It should state you have 0 or 99 points. Press A and you will be able to select your powers. Note: If it states you have 0 points, it is because your powers have been pre-selected; find the selected powers and take the points away from them.

Defeating Blue Reborn
Trap him in a corner then keep slashing him. This tactic may not always work, but it will make him weaker.
Defeating Desan
Use Force Speed to move faster, then attack him with as many blows as possible.
Hide behind one of the pillars in the four corners of the floor. Desan will throw his lightsaber at you, but it will cut through the rock pillars and will fall on him, killing him instantly. Note: Use the invincibility beam in the center of the room first so his saber does not hit you.
Select Mind Trick for your Force weapon. When he shoots his lightsaber, block it away to the ground. Use the Jedi Mind Trick and attack him. He will be vulnerable for about five seconds.
Defeating Stormtroopers
Push them using Force Push, then run up to them close enough that you touch them. Then, push them. Note: This will only work if they touch a wall. When you are fighting Stormtroopers or Swamptroopers, use Force Push, then throw your lightsaber at the fallen enemy. This almost always kills them instantly. To safely disarm Stormtroopers, use your Force Pull to pull their guns out of there hands. Whenever you face Stormtroopers near an edge, you can push them off.
Easy kills
If you have Saber Defense to the top in Force powers, it is easier to kill enemies with lightsabers. Defend their blows and sometimes they will get hit and get killed.
When you get to the harder levels, you will find out that Dessan (Dark Jedi) had followed you to the Valley of the Jedi and was giving his fighters the power of the Force and created fake Jedi. You will have to fight these people throughout the game. If you do not want to waste your time fighting them, then use Force Speed. You will move incredibly faster than your opponent and can attack them while his lightsaber is going too slow.
After you get Force Grip, use it and Saber Throw to kill the "fake" Jedis. This take longer as you progress in the game, but it still works. To kill opponents faster, change your lightsaber mode to red (strong).
Force Jump
At the top of your jump, use non-Force jump. Note: This does not always work and may only work in some levels.
