As promised Angry Birds Seasons is out now. Both iOS and Android versions include 25 Christmas-themed levels, but you can’t play all of them at once. Each level becomes available on the corresponding day of the month, so you’ll have to wait until Christmas to beat the pig boss.
The update for the Android version also includes all 47 Halloween levels (including the two bonus ones) and you can get it right now from the Android Market. And it’s free of course.
The iOS Angry Birds Seasons update for the Halloween Edition is also free and should be available any moment on the AppStore (we’re still waiting). In case you’ve missed the Halloween Edition, you can get the Seasons version (including both Halloween and Christmas chapters) for 0.79 euro from the AppStore.
Unfortunately Symbian^3 and webOS won’t receive the Seasons update.
December will also bring 15 new levels to the original Angry Birds plus the Mighty Eagle bird. There is no info on the exact release date, but the first confirmed platforms are iOS and Symbian^3.
