Danger Zone

Danger Zone is an episode of Angry Birds Space featuring 30 extremely challenging — brainteaser-like — levels. For iOS, this episode is available as an in-app purchase, with the first level free for trial. Samsung Android users can access this episode free for 3 months from launch date. The episode is available for PC users (cost-included), accessible after passing all 30 levels of Pig Bang.

The level numbering is "D-1" through "D-30", implying that Danger Zone is a nonsequential episode.

Think you can defeat THE DANGER ZONE? This special episode is filled with 30 of the most difficult Angry Birds levels EVER constructed -- we let our level designers go crazy with these ones, and they came up with some brain-wracking levels. Even some of us here at Rovio HQ, where we consider ourselves to be expert pig-poppers, have found ourselves sweating in The Danger Zone!
