Mighty Eagle coming soon to Rovio's Angry Birds Seasons for iPhone
Total destruction
Those clever folk over at AngryBirdsNest have discovered several Angry Birds Seasons Game Center achievements, pointing towards the arrival of the Mighty Eagle.
The achievements (which you can see in the screenshot below) can be unlocked by simply purchasing the destructive beast, and by collecting 30, 60, and 120 feathers.
In case you're unfamiliar, you can grab the Mighty Eagle through an in-app purchase, and you can call it into action by firing a tin of sardines from your slingshot.
The winged beast will then soar downwards - once every 60 minutes - destroying most of the level's scenery, and taking out all green swine present.
You'll then earn a feather if you manage to accumulate 100 per cent destruction.
Flying high
Angry Birds Seasons is, of course, a spin-off from the original offering, which features several seasonal themes such as Halloween and Christmas.
You can grab it from the App Store for 69p/99c for your iPhone, or £1.49/$1.99 for your iPad.
