If you are a Angry Birds fan and you own a windows phone, there is some great news for you. The original game which is normally priced at $ 0.99 is now available for free download, till May 15th. Also, the Windows Phone 8 version will also have Xbox Live integration with new achievements and leaderboards.
Moreover users will now be able to play new level packs, including Mine and Dine, Birdday Party, Surf and Turf, and Bad Piggies. In case you already own the old game, it would be a great to download this one.
Downloading this new, improved version will not you loose the old one. Even your stars and level progress will remain untouched, as the two versions are completely separate.
"This will be a completely separate download from the original Angry Birds title that some of you may already own. The reason why we're re-releasing the game is that it will be technically easier for us to support in the future, so we're really happy to get this out there!" said Rovio (Angry Birds maker) in a blog spot.
You can download the the new version of Angry birds from Windows Phone Store.
