Angry Birds Second Birthday Invites a New Bird to the Party

Angry Birds has published another special-occasion update, this one celebrating the runway mobile hit's second birthday. With it, you get 15 new levels and a new projectile, the Orange Bird, which "propels any object it touches."

The update is to the main game, which is still 99 cents for the iPhone, $4.99 for the iPad. The news release announcing the update only mentioned the game's iOS versions.

Additionally, the "Birthday 2.0.0" update offers 15 more levels in which you may fling the aforementioned rancorous avians into cakes, balloons and other festive objects. There are also new achievements to be claimed through Game Center.
