Now that the Executor has been destroyed and the shield is finally down, it’s time to commence the attack on the Death Star properly. First, there’s another fighter screen and a Star Destroyer to clear out of the way.
This is basically Mission 1 redux, only with a Star Destroyer to beat, and the need to get to the initial entry position within a time limit.
It’s not terribly difficult. Focus on the fighters, then go after the shields on the Star Destroyer. With the Falcon‘s turrets, dealing with the fighters isn’t too difficult, and you should be able to make it to the nav point with a minute or two to spare.
