Enter LSULJ as your code from the "Extras" menu to unlock the Battle Droid Commander.
Beat the Zillo Beast
To beat the Zillo Beast, get about 100,000 credits; you may not need that much, but just to be safe get it anyway. Go to every build area and build a turret on each one. Check every build area and find the one that will let you build tanks. Build a bunch of X-130 Tanks and you're done. All you have to do now is watch. And maybe help a little.
Get studs again
If you collect all the studs in the spacship go to the character custimization you don't have to click it then go out and you can get all the studs again.
Making Money
Score modifiers are your friend: Aim to get the red bricks which unlock each one, and have all of the ones you've unlocked on at once. The purple stud which appears next to the shop normally gives you 150,00 or so, so with modifiers:
2 x 15,000=30,000 2 x 4 x 15,000=120,000 2 x 4 x 6 x 15,000=720,000 2 x 4 x 6 x 8 x 15,000=5,760,000 2 x 4 x 6 x 8 x 10 x 15,000=57,600,000
That's a lot of studs! Unlocking all the characters/hints only costs around 4,000,000 total, so you're all set.
