Easy mission completion:
On both Anakin's and Obi-Wans storylines, there is a mission where you must last 2:00 until the Clones arrive. To complete those missions easier, go up and down on the screen while jumping. The most they will hit you is four times.

How to beat Jedis:
When fighting a Jedi, wait for his special attack then block it (press L). After this is done, attack him as hard you can.

How to beat the AAT tank:
Droids will always spawn at both sides of the tank. If they have blasters, deflect them and they will hit the tank's weapons. If they shoot grenades, Force Push these towards the tank. If they are unarmed, they will leave parts behind after being destroyed. Force Push these towards the tank. When the tank has lost all its weapons, a droid will come out of the tank. Deflect its shots to destroy the droid. REMEMBER: At first the tank will fire normal lasers, which can also be deflected towards the tank.

How to beat the Droid Starfighter:
Stand at the bottom of the screen. When it flies over you, use your lightsaber to slash upwards, then move upwards to avoid the bombs. When it flies over the ground, jump over it and use a jump attack to damage it. Walk back to the bottom of the screen. Repeat this until it becomes a walker. Then, jump over the laser beam and use jump attacks to damage the head. You should be able to defeat it without taking any damage. REMEMBER: do not try to Force Push/Pull the bombs towards the ship -- it will not work.

Anakin: Defeating bodyguards:
In Anakin's story mode in the Utapau System, instead of fighting all of the bodyguards with staffs, ignore the yellow ones and take out the red ones. This will cause the others to retreat.
