Red Planet 5-12 is the 12th level in Red Planet.
The Pigs are in the another planet. Make this level harder to win, but fortunately, you have supplied with 3 Lazer Birds.
Launch Lazer Bird south, redirecting him towards the fiery asteroid. The resulting chain explosions will send enough debris to destroy most of the pigs. Then use the second Lazer Bird to target the Bottom rock which should clear the rest.
Second Rover is here! It's hiding on the further part of the right planet. Use Lazer Bird to claim it.
