Danger Zone D-28 is the twenty-eighgth level in Danger Zone. The objective of level D-28 is to use the birds to eliminate all the pigs. Get at least 47,000 points for 3 stars.
Send the Lazer Bird below the first planet, outside or inside of the gravitational field, and redirecting through the small gap on the right side. Send the next Lazer Bird just inside the pull. Redirect him into the pig and wire tower next to the pig. This should trigger the TNT, causing debris to finish the last pig. (Both shots are very challenging.)
