A long time ago in a galaxy far, far away... a group of desperate rebel birds faced off against a galactic menace: the Empire's evil Pigtroopers!
Rebel birds, striking from a hidden base, have won their first victory against the evil Imperial Pigs. During the battle, Rebel spies managed to steal secret plans to the Empire's ultimate weapon, the PIG STAR, and are racing to deliver the plans to the Rebel Birds. Now they need your help!
Join an epic adventure with the Angry Birds in the legendary Star Wars universe! Use the Force, wield your lightsaber, and blast away Pigtroopers on an intergalactic journey from the deserts of Tatooine to the depths of the Pig Star -- where you'll face off against the terrifying Darth Vader, Dark Lord of the Pigs! Can you become a Jedi Master and restore freedom to the galaxy?
Time to grab your lightsaber and join the adventure! May the birds be with you!
