Christmas Angry Birds swoops in

Cherished iPhone game Angry Birds has had a festive makeover. Quick! Act surprised.

Angry Birds Seasons costs 60 pence and adds 25 days of themed levels, which amounts to "hours" of gameplay.

"We'd like to take this opportunity to give everybody our Season's Greetings and wish Happy Holidays to all of our fans. We thank you sincerely from the bottoms of our fluffy hearts for putting Angry Birds in the iTunes App Store Hall of Fame," developer Rovio wrote on the iTunes Store.

David Cameron plays Angry Birds, apparently, and so should you at that price. Check out Eurogamer's Angry Birds Halloween review for an idea of what to expect.
