There is a Collectable Item hidden in Angry Birds Star Wars II Escape to Tatooine level P2-12, on the far right side of the level. In the video, we accidentally obtain the Collectable Item with a random piece of debris being launched from the TNT blast below. Whoops. But nonetheless, we chose to continue recording to show you a legitimate strategy.
Fling the Battle Droid straight ahead, shooting the leftmost plank of the bridge with the laser blaster. Repeat the shot to destroy the bridge. Arc the final Droid through the gap where the bridge used to be. As it falls through the gap, aim for the Bonus Box with the blaster. Pew! Pew! Got it!
Go back to the Complete Star Wars II Bonus Boxes Guide. If you have a different strategy feel free to leave a comment below.
Just lucky, I guess. Blew the bridge, platform goes right, bone gets hit over hill and takes box in two easy shots.
Some other variant because a video look like a funny joke ;). Crash a bridge. Fly an arc over left rock and shoot by bones aiming at the box. After clearing a way repeat and shoot easy way to finish.
Another strategy (a bit like yours) I used was: Shoot the platform to clear the way, except a tower of bones (although sometimes it could topple with the TNT blast). Second droid will either go through the tower, shoot the box, or both, if lucky. Use the last one if necessary. Pew Pew!, you got it!
