AT-ATs running amok? Sounds like a job for Princess Leia.
With Angry Birds Star Wars, Rovio chose to focus on Episode IV: A New Hope, at least initially. Now it's time to stop teasing fans and deliver playable stages from Episode V: The Empire Strikes Back, specifically puzzles inspired by the epic battle on the icy planet Hoth that opens the film. We've been waiting for these boards to unlock, and that'll happen tomorrow, November 29. On top of that, Princess Leia joins the cast, and it will be interesting to see how her unique power changes the gameplay.
That said, the Angry Birds Star Wars Hoth update will be available free of charge.
