Finally, after a month of trying, I finally finished this mission. Argh! RC #13 is definitely the hardest mission so far.
Technically, this mission doesn't sound that difficult. You drop in, go full throttle to kill an Imperial Shuttle before it boards the pirate Dreadnought, engage waves of pirate and Imperial fighters, drive off the Imperial Star Destroyer, fight off a squadron of Assault Gunboats, then all you have to do is wait for the Corvette Storm to jump out and the mission's over.
Of course you and your wingmen will have to have fought through over sixty enemy fighters to get there, plus the previously mentioned Star Destroyer.
Also, there's one extremely important factor: Don't identify the Dreadnought until the ISD Rage has been driven off. That's what triggers the Corvette.
Just two more missions left!
