Rovio Mobile just doesn't stop cranking out the good stuff, not that we're complaining. In addition to its Advent Calendar type seasons update, the developer has updated Angry Birds HD for the iPad. The update is Angry Birds 1.5 and contains 15 new levels set in the Wild Wild West (in case you're missing your sunshine this time of year).
The new levels are set in a cluster called “Ham 'em High”. This update also comes with the much awaited mighty eagle. While the eagle is an awesome bird, it's a withholding one. You have to pay 99 cents to use it and it can only be used once an hour. Other features in the update are a new golden egg and support for Game Center.
Rovio has said on the iTunes app store: “We’d like to take this opportunity to extend our infinite gratitude to friends of our fierce birds everywhere. We thank you sincerely from the bottoms of our fluffy hearts for making Angry Birds the highest rated and best selling game ever on iTunes!”
