Hmm. I'm on the last Atreides mission, against the Harkonen (ie, I defeated their area on Arrakis, and their stronghold on their own planet), and now I'm on the mission where I'm against the Guild, the Harkonen, and the Ordos, trying to destroy some Emperor Worm. This is possibly the hardest mission I've come up against so far, and I was just wondering if anyone had any useful tips or hints for this one, as I keep getting totally destroyed, after a few successful waves of defense. Cheers. Mort.
