Our strategy for Angry Birds Star Wars Death Star 2 level 6-11 is to fling the blue up towards the fringe of the top atmosphere, splitting early so one blue bird hits the top floating pig. One of the remaining blue birds should hit the vertical beam of ice holding up the cannon, causing it to fall and send lasers bouncing off the metal walls. This should be enough to finish off the level. The score in the video below is 77,240.
