Play as a Jedi or certain Sith (for example, Anakin Skywalker and Count Dooku) that have Force Jump. A certain part of the level has a ship in a giant "dome" where you can spawn players. Go to the top of the ship and spin around so that you see an open exit and what looks like a gate-like object. Move your Jedi or Sith into the gate and go all the way inside. Turn around to face the outside then tap Force Jump until your energy runs out. Han Solo, Princess Leia Organa, Bobba Fett, Jango Fett, The Emperor, and Darth Vader cannot do this. Then, move out of the gate. Your character should be floating. If you use Force Jump again or get attacked by another Jedi or Sith's lightsaber (not by saber throw) or use Force Run, you will go back to normal. If you are attacked by someone who has a gun, nothing will happen. Note: Using the "Invincibility" code before doing this is recommended.
