Used quite a bit and only approx. 3MB. Here's what I used (breaking out what I would call a "synth and guitar orchestra):
4 Big Electric Lead guitars (They sound quite good when they have 2 notes going at a time don't they?)
1 Cheerful Trance synth lead
1 Arena Run synth lead
2 FM Bells A mallet synths
1 Berneray Chill synth texture
1 Moonbeam synth lead (Which you hear pretty well when the guitars hit 2 notes. It's what you hear in the background of that. Then the others are added.)
1 Ornos Brass synth texture.
2 Pop Kits (For the cymbals)
2 "Kits" (Added Apple Loops. They sounded good.)

I hope you guys like this.... if you're one of the people who hate Star Wars (and if that's the reason you rated the "Death Star Attack" low), DO NOT RATE. Added to this. If you rate 1 or 0 PLZ tell why? Plz? Oh and sorry about the long pause at the end.
