Instant action missions
Successfully complete a mission in historical campaign mode to unlock the same mission in instant action mode.

Destroying AT-Ats
Choose the pilot, and get into a Snow Speeder. Find another infantryman and get him into the copilot seat. When you fly to an AT-AT, pull back the Right Analog-stick and start circling it, while trying to stay low to avoid its laser cannons. Eventually your copilot will shoot the towing cable at its legs. Continue circling for about four times around, and it will explode. Also, always attack the AT-AT in the back to avoid laser cannon fire from the other vehicle.

Another way to defeat the walkers is to take control of the Snowspeeder as the pilot. When you get near the walkers, switch places so that you are in control of firing the tow cable. When the cable is attached, the CPU pilot in the speeder with you will complete the final wrap around.

Battle Of Hoth (Galactic Civil War): Defend against Snowspeeders
To defend your AT-ATs against Snowspeeders, simply move them close together. To wrap around the AT-AT's legs, a Snowspeeder must get close. The second AT-AT next to you will keep them farther away. Also, two AT-ATs can rip apart enemy lines better the one.

Tattoine Dune Sea (Instant Action): post and destroy enemies faster
Capture all the command posts around the Sarlaac Pit then take one of the Rebel Speeders. Land it next to the pit. All of the enemy troopers should come close or next to you, and be dragged into the Sarlaac Pit.

Recon Droid
The sniper's Recon Droid has a self-destruct mode. When you press [L], a timer begins. This is an effective means of taking out strategic turrets. This works best when you begin the countdown before you arrive at your target.

Killing Tusken Raiders
Steal Rebel tank and go to a Tusken camp. Sit there with the turret gun and kill them. Do not use the cannon or they will know that you are there.

Bomb run
Select any level as either the Empire or the Republic. They both have a person with a jetpack. Spawn anywhere with a jetpack character. Wait for your jetpack to fully charge. When you are ready, jump into the air and start throwing grenades wherever a big cluster of enemies are found. This trick works better for the Republic Jet Trooper, because he can hover instead of jumping high and he has more grenades. For example, if you are a Republic Jet Trooper, jump in the air, then go forward while throwing grenades repeatedly; or hover in one location and focus a few or all your grenades in one location. Also, if a grenade hits an enemy, it will hurt their health.

Unlimited health or ammunition
Stand, crouch, or lay near any one of the replenishment depots. Camp there with a sniper rifle and keep firing.
