Angry Birds Seasons went 2.0 today, and the Halloween update marks the start of the 2012 Angry Birds season. Like most Angry Birds updates, this one comes packed with a bunch of new levels to play through. Unlike most Angry Birds updates, this one includes a brand new bird.
Affectionally dubbed "Orange Bird," this bird massively inflates when you tap the screen. This allows you to do things like launch it and have it fall down a narrow channel in between two nearby pig forts, then tap to have it blow both down as it expands. So far it seems like a slight variant on the black bird, although I've yet to play very many of the new levels to see how the orange bird truly shines.
