Hi I'm called Adam.... I need Help badddd!..... On misson 5... Theres a..

You mean the Coruscant mission? If thats the case, you need to deflect the lasers shot by both the droids and the tank, also, there's another tank mission later in the game, it's the first mission (using Anakin) you do as Dark Anakin, when you get that far, post questions on how to defeat it, I can't answer it now, because it's not the question you're looking for

Heya I'm scottie! And dude I have an answer to your problem, when fighting the trade fed tank hold down L while pressing B when the driod fire at you. This will course the bullets to rebonund off your saber and damage the guns, once you destroy the lazer cannons the tank will move 4ward and start using a machine gun yet agin use the same technique as I stated b4, then the tank will open fir with the main gun use the technique again, and lastly the top of the tank will open and a driod will appear use this technique of holding down L while pressing B to kill the driod and bamo! You finished the level, glad I could help you out

You have to reflect the ammo coming at you to the tank. By doing this you need to block the lazer right when it gets infront of you. The lazer will fire back and hit the guns.
