Angry Birds fans are being offered 15 more levels to beat via a last-minute update that brings the game to version 1.5.0 on the iPad side. A free download for existing owners of the game, Angry Birds 1.5.0 also features a new theme in the Frontier Badlands, a new Golden Egg, Game Center support, and more.

Angry Birds is a puzzle video game developed by Finnish development studio Rovio. Since its release for Apple's iOS platforms, over 10 million copies of the game have been purchased.

The title is also available for other touch-based smartphones.

“The survival of the Angry Birds is at stake,” goes Rovio’s iTunes description of Angry Birds. “Dish out revenge on the green pigs who stole the Birds’ eggs.”

“Use the unique destructive powers of the Angry Birds to lay waste to the pigs’ fortified castles. Angry Birds features hours of gameplay, challenging physics-based castle demolition, and lots of replay value. Each of the 210 levels requires logic, skill, and brute force to crush the enemy.”

The new iPad release is dubbed Ham ‘Em High - A Scorching Hot New Update” which delivers the following:

- A NEW THEME IN THE FRONTIER BADLANDS - 15 NEW LEVELS – NO BELLYACHIN’ - A NEW GOLDEN EGG FOR Y’ALL CITY SLICKERS - GAME CENTER SUPPORT - COWBOY UP WITH THE MIGHTY EAGLE

Rovio took this opportunity to extend its “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!”, the developer states.

For iPhone and iPod touch users, Rovio has recently released Angry Birds Seasons, an update that brings 25 daily new levels for users to enjoy while counting down the days until the release of Angry Birds Christmas Edition. Learn more here.
