Danger Zone D-30 is the last level in Danger Zone. The objective of level D-30 is to use the birds to eliminate all the pigs. Get at least 115,000 points for 3 stars.
Getting 3 stars is very hard.
Rightmost bubbled small pig is very tricky.
TNT helps much but it's the problem for the next bird.
Send the Lazer Bird just outside of the gravitational field of the bottom planet. As it drifts off screen, redirect him back into the stone planks in front of the far-right pig. The bird should both pop that pig and bounce into the TNT on the left. (The first shot is extremely challenging.) After the smoke has cleared, send a Lazer bird just over the tower of the top-right planet, then redirect into the TNT. (The second shot is depend on luck because the ruin of the X-shaped structure.)
