Avian Sins

Avian Sins is the Danger Zone/Path of the Jedi Episode of Angry Birds Heaven Aviators. It is Insanely Hard in average, but completing certain levels may upgrade your Birds. This is considered to be the hardest episode of ABHA, because some of them are Hardly Possible (HP) levels. It can be unlocked by getting 3 Stars in Certain Levels and Episodes, or buying it for 0.99 USD.

There will be another Danger Zone episode called "Savage Superior"
