Imperial troops are attacking Echo Base in the latest update for Rovio's Angry Birds Star Wars. The free-to-download content pack adds a series of levels set on the ice planet of Hoth, seen throughout the first third of Star Wars - Episode V: The Empire Strikes Back.
The new trailer highlights ice skating, pig-commandeered AT-ATs, though there's no gameplay featured. I can tell you what it looks like: Angry Birds in a snowy sci-fi setting. SPOILER!
