The best strategy for Big Setup level 10-11 is to fire the first Big Brother into the horizontal stone plank above the first helmet pig. This will push the structure to the right, popping most of the pigs and reducing the pigs’ fortress to a pile of rubble. Launch the next Big Brother into the debris, popping the pigs in the middle. Destroy the wooden planks on the right side and the pig over there to finish the level. The score in the video below is 131,230.
