Advanced Missile Technology
In the level "Smuggler Alliance", destroy the STAPs attacking the homestead. When all are gone, wait and look behind the homestead and you will see two more STAPs fly down the hill. Destroy them before they shoot the civilian and he will announce that he has something to show you for your help. Follow him to a farm in the nearby valley and he will unlock a metal gate in front of the farm allowing you to obtain the light-blue bonus icon. Your missiles are now much more powerful.
Advanced Bomb Upgrade
On the Glacial Grave level, about 3/4 of the way through the canyons, just before you have to steal a gunboat, there is a dark corner in a canyon with a tall tower and green-domed building below it. Shoot that building and the light-blue bonus icon will appear. Your Naboo Bomber will now be able to earn medals a bit easier.
Shield Technology Upgrade
On the level "escape From Theed", about half-way through is an AAT sitting in an archway firing at your fellow officer. Shoot the AAT and then enter the small room it once blocked where you will find a light-blue symbol that will upgrade your shields for all crafts on any level.
Rapid Fire Lasers
In the level Sanctuary, get your N-1 star fighter from the security hanger and defend the convoy. defeat the three groups of fighters (four to a group, first group is bombers, then fighters, AATs and finally another group of fighters). After those you'll be up against lots of single fighters, but they are not any threat. Right before the rocks you shoot down/Devv shoots down, you will see a tiny path on the right of your radar. Follow it and you will be in a large valley with a mountain in the center and this star thing that circles the mountain. Go around the mountain. You'll see lights that go in two rows. Follow them and pick up the bonus which allows you to fire super-rapid lasers. YEY!
Seeker Cluster Torpedoes
In the level Corescant Encounter(Get All Silver Medals) chase Darth Maul until he makes a steep drop down and turns left. Follow him and you should see pipes above you. Fly over them and turn right. You now have the bonus.YEY!
In the level Liberation of camp 4,in the last area before you complete the level,(where your friend finally gives you air support and there are tons of ATTs)go to the shield generator and destroy it, allong with the turret. Then turn left and go up the nearly invisible ramp slowly. When at the top, turn left and boost. Follow the little canyon to the bonus.YEY!
In the level Borvo the Hutt, defeat the ships and blow up the proxies at the beginning of the level. Then blow up the turrets and go to borvos isle, but don't go in. Instead, head left around the isle until you see a small and low island. In the approximate center, there should be four trees in a square shaped concrete fence that is very very tiny. in the center, there is the bonus. YEY!
Advanced Laser Technology
In the stage "Liberation Of Camp 4" there are 3 shield generators that have to be destroyed to free the prisoners. You have to climb a steep mountain pass to destroy the third; this generator is the only one protected by a turret. After you destroy it, turn to your left slowly and you will see a little pass. Follow it to the end and you will discover the blue symbol. Be careful climbing down!
In the level Sanctuary, are you having a hard time with getting friendly saves? Well, you will need this for getting the gold, so do this as I say. It must be done quickly! Get the N-1 from the hanger. Then go to the village being attacked by bombers. Destroy the ground units and as you will find the Star Wars Big Ben that fell over during the cutseen. There should be two Flash Speeders in the middle of that which ask for your help. Simply Blow up the fallen Big Ben, escort them to the ruins and voila! Two more friendly saves plus that elusive gold medal. YEY!
Darth Maul's Sith Infiltrator and Platinum Medal
To get Darth Maul's Sith Infiltrator, Beat all the levels with a Gold medal. A nearly impossible task. Then you get a level called The Dark Side, where you are Darth Maul in the Infiltrator and you have to destroy Naboo forces. If you beat it extremely well you can get a platinum medal. Once you do you can be the Sith Infiltrator in any fly mission. It's lasers are twice as powerful as advanced normally are and fire about 20 a sec.(Yes, I have no life.)YEY! P.S.: there isn't a bonus.
On the level after The Queen's Gambit, protect the commandoes and get ahaed of them. Now, if you're very impatient and don't like to wait for the transport, hold down the brake and the laser button. Press the heavy laser button while holding down the other two. Eventually, the hanger door will explode without the commandoes setting the charges.
HINT: This code works easier if you have the advanced laser and rapid fire laser power-up. It's also a good idea to clear out the battle droids and the destroier droid before you try to tackle the door.
