Easier completion of Tantive IV mission
In the mission on Tantive IV (blockade runner), the first and last objective are very difficult. At the start, once the door explodes and opens, use your thermal detonators. Get to the CP and keep dodging bullets and firing while standing near the CP until it is turned to your faction. This may take a few attempts, but it will work. Use Darth Vader after you have captured it. Use a regular Stormtrooper to take care of Leia. She should be around where you started the level. Use your grenades to soften her up, then your rifle to finish her off.
Easy slicing points
Sneak aboard the Rebel capital ship and wait by the Y-Wing until someone gets in it. Then, use your torch to slice into it. You can cause it to explode if in the air, getting points in the process. Repeat this as many times as desired.
Easy tank kills
Place proximity mines on the tanks (Vanguard, Heavy Trooper, Shock Trooper) and any other kind of vehicle, except for the assault vehicles such as the AT-TE. A more difficult way is to use a sniper technique. Fire from a safe location. Target the vehicle, wait until the reticule turns red, then fire. Another useful bombardment unit is any that carry a recon droid. Their self-destruct mechanism makes them a formidable bombardment unit.
Infinite hero or villain
Select Instant Action mode, choose your levels, then go to the options menu before you start. Select "Hero", then change the options to Best Player, Time Limit 1 second, and the time for hero to become available to "Always". You can start the game selecting the hero, and when you die you can pick them again immediately. Additionally, select Instant Action mode, choose your levels, but do not launch. Go to the options and choose the "Hero" selection. Change the options to the following: Best Player, 4 Points, and the time for the hero to become available to 4 seconds. Your hero or villain can still die and the meter runs out, but you only need to kill four people for four points to unlock the hero or villain again. Also, if you get the points when you are playing as the hero or villain, when you die while playing as the hero or villain they still count as the points; you can pick to play as them immediately.

Playing as a Jedi hero/villain
It may be very easy to kill people as a hero, but there are some special moves and techniques other than the standard saber combos. You can do extremely deadly and long combinations of lightsaber strikes against enemies by Force Running/Sprinting into a group of them and pressing Attack while still sprinting. This releases a group of moves that are much deadlier against groups of opponents. This is useful when clearing hallways or passages. You can also do lightsaber combos while Force Jumping by pressing Attack in mid-air. This is useful for killing Jet Troopers as a Jedi or taking a out lightly armored vehicles or any vehicle low on heath that is higher up. You can use the "lightsaber lock" to block enemy fire coming directly at you. Make sure to face your enemies as best as possible to block their fire, and use the crosshair that appears temporarily in this mode to better aim your ranged attacks (Force, lightsaber throw). Instead of running around the map randomly trying to kill anyone you see, find a group of opponents, then activate lightsaber lock to block all their shots as you Force Run at them and then unleash a deadly combo while you are in their midst. Also, some heroes are better than others. Even though you have a limited choice for each map, try to choose a team that has a better hero or villain. Some Jedis are much faster and lethal in terms of close combat and lightsaber skill. Obi-Wan Kenobi, Darth Maul, Luke, Pilot Luke, Ki-Adi Mundi, Ayala, Yoda, and Mace Windu are recommended if you like using a lightsaber and running around. Other heroes and villains are much slower with a lightsaber and are not as good at fast or close combat, but are slightly more powerful than the others and have a better understanding of the Force. These characters include Darth Vader (Force Choke), "The Emperor" Palpatine (Sith Lightning), and Count Dooku. Use a character that best fits your playing style.

Regenerate health and ammunition
If there is an ammunition or medical droid on the other side of a thin wall (i.e. in space if you go into another hangar and the main room has thin separator walls between the doors and the droids), it can heal you through the wall. No one on the other side can shoot you unless they use a bomb, grenade, rocket, etc., which rarely happens.
Repairing shields
You can always repair your shields. Just use the torch, but do not get too close to the glass or it will not work. This takes awhile, but is helpful. Also on ground battles you can use the torch to slice (hijack) enemy vehicles.

Slow enemies from getting to their ships
Get into a heavy transport (for example, a LAAT Gunship or Droid Gunship). Make sure no one else is in it except you, then fly over to the enemy hangar. Land and get into one of the scout fighters in that hangar (for example, a Jedi Starfighter or Tri-Fighter). Quickly fly back to your capital ship. To do this even more quickly, do the boost, and if the enemy frigates are not destroyed yet, fly out of the hangar, go down a good ways, then level your ship out again. When you have reached your hangar, land and see if your other transport is there. If it is, get in. Make sure no one is in it but you. Repeat the process described again. If it is not there, either just waste time and wait, or get into a X-Wing or ARC-170. There will now be two of your transports in the enemy ship, and they will spawn many of your men. By doing this, you have bought yourself lots of time to disable the enemy ship. It is important to make sure no one but you is in the ship because if someone else is in there they will not get out when you land; and if you get out, they will take off and crash.
