Danger Zone D-27 is the twenty-seventh level in Danger Zone. The objective of level D-27 is to use the birds to eliminate all the pigs. Get at least 148,000 points for 3 stars.
Right side of the first planet has the walls, so they're very annoying
Getting 3 stars is extremely hard.
Send the Red Bird below the first planet, through the gap on the right side, and triggering the TNT. This will set off a sequence of explosions. It is incredibly important to pop the pig perched on the wires on the right planet. (The first shot is very challenging.) Send the first Lazer Bird into the gravitational field of the top planet. After it loops around, redirect him into the TNT on the right planet. Repeat this shot with the next bird, but redirect into the TNT of the left planet.
