Danger Zone D-11 is the eleventh level in Danger Zone. The objective of level D-11 is to use the birds to eliminate all the pigs. Get at least 98,000 points for 3 stars.
This level is not hard but getting three stars is rather hard.
Send the Ice Bird to the rightmost structure, causing the icy asteroid to break apart. As the right structures collapse and the tower in the middle of the level collapsed and hit the TNT in the middle can detonate to clear the entire level.
