Advanced Missile Technology (hint)

At the imperial construction yards go to the first AT-AT that you see. Go past it. Go over the platform with tie fighters sitting on it to the next one where there is a transport ship taking off from it. on the right side blow up the buildings. In one of them there is a little yellow thing pick it up. Thats the advanced missile technology.

Taloraan Battle (hint)

In the battle above Taloraan are you having trouble at the end and finding the powerup?  Well this is your answer!  Go as low as you can and the Tie Intorceptor won't see you.  The best ship to use on my opinion is the Mulenium Falcon sneak up and kill the Tie.  The powerup is in the middle of the city.  Now to end the mission!  There are no Tibanna tanks on the top.  Shoot all the turrets as quikly as possible Then shoot the Tibanna.

P.S.
The unlimited lives cheat is useful in this mission.

Advanced Technology (Chandrilla)

If you're haning trouble finding tha advanced Technology in Blockade at Chandrila,you're in luck.Follow the train to the city.Once you get there follow the edge of the city and you'll see 3 pointy buildings and an AT-ST.
Destroy the AT-ST and the advanced technology will be floating,pick it up.

Extra Kills (1st level hint)

In the first level of the game, the object is to destroy the PROBE DROIDS and TIE BOMBERS. After you destroy the last group of PROBE DROIDS(if you did it in the order the radar told you), fly to right. There will be 4 STORM TROOPERS there. 2 on DEWBACKS and 2 walking. You have to kill these to get a gold medal

Bonus: Jade Moon, Good Shields

To get better shields go to the shield generator. DO NOT blow it up. Just go down the canyon until you get to the second split in the canyon. (Go either way on the first split of the canyon) Go to the right on the second split and at the end of the canyon there is a building and a missle turrent. Blow them both up and get the yellow box. Then get out of there the same way you got in and complete the level.
