Legend of the Guardians: The Owls of Ga'hoole

Again, in this game, "turrets" are catapults. You will have to "bomb" them with hot coals. Simply collect some hot coals from your flying "coal-supplying" allies and target and bomb the catapults (by pressing , when prompted). By completing all of the story and bonus missions, you shouldn't have to replay anything to get this trophy. However, if you do, or if you're getting too anxious, you can always replay bombing challenges.
