In what is becoming a trend over at Rovio - the Finnish studio behind the most popular puzzle game for iOS devices - Angry Birds Free 1.0 and Angry Birds Free HD 1.0 have been released to the App Store with no official announcement.

Rovio has bundled 12 brand new levels for iPhone and iPad gamers alike in two new Angry Birds 1.0 releases - Angry Birds Free, and Angry Birds Free HD.

The description of Angry Birds Free reveals that the new levels are broken down in four new mini episodes and that the “Free” version dumps Chillingo’s Crystal for Apple’s Game Center integration.

The game also links to Angry Birds Seasons and plush toys.

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

“Use the unique destructive powers of the Angry Birds to lay waste to the pigs’ fortified castles.”

The Angry Birds Free features are listed as follows:

- 12 LEVELS NOT AVAILABLE IN THE FULL GAME - 4 MINI EPISODES - GAME CENTER SUPPORT - LEADERBOARDS AND ACHIEVEMENTS

“Angry Birds Free features challenging physics-based demolition gameplay, and lots of replay value,” Rovio Mobile Ltd. adds.

“The 12 levels, set in 4 mini episodes, have been created specifically for Angry Birds Free. Each of the levels requires logic, skill, and brute force to crush the enemy.”

“Protect wildlife and help save the Angry Birds!” the studio concludes.

Angry Birds Free and Angry Birds Free HD require an iPhone, iPod touch, and / or iPad running iOS 4.0 on iPhone and iPod touch, and iOS 3.2 or later on iPad.
