The sequel-tastic space saga continues with yet another content update to Angry Birds Star Wars II.

Released last September, Angry Birds Star Wars II is the follow-up to Rovio’s original Angry Birds Star Wars game. Based on the “Star Wars” prequel trilogy, Angry Birds Star Wars II lets you choose between using the Force with the birds against the Pork Federation or joining the Pork Side with the pigs.

And following the latest update to the game, you can choose to play the 20 new Bird Side levels or the 20 new Pork Side levels. The update, which introduces the latest Battle of Naboo chapter, also lets you unlock four new secret levels and three free characters:

  • 20 NEW BIRD SIDE LEVELS! Face the enemy on the devastated battlefields of Naboo and then continue the battle in space!
  • 20 NEW PORK SIDE LEVELS! Launch an attack on Naboo’s capital city and face the Jedi Master Qui-Gon Jinn in the big boss fight!
  • NEW SECRET LEVELS! Find the hidden maps to unlock 4 secret levels!
  • NEW FREE CHARACTERS! Play as Padme, Captain Panaka and Zam Wesell for free!

The new version of Angry Birds Star Wars II is available now in the App Store as a free update or as a new $0.99 download. The game is compatible with iPhone, iPod touch, and iPad running iOS 4.3 or later.

Angry Birds Star Wars II received its previous — and first ever — update early last month. That update saw the arrival of new secret levels, new reward levels, and new characters including Hologram Darth Sidious, Silver C3PO, Red Battle Droid, and Shadowtrooper.
