The Birds are back this summer
NFC-based features will let you unlock stuff depending on your location angrybirdsnest.com

The birds are back this summer with a new vengeance and they are furious about the green dirty pigs that are stealing their eggs.

The phenomenon will receive an update to the Angry Birds Seasons titled “Summer Pignic”. The Finnish developer Rovio has just launched a new preview trailer.

However, little has been disclosed by the video where it says it is one bird and only one mission which is to save the eggs from the evil green pigs.

The company has not revealed the release date of the update. Various NFC-based features are also expected to arrive with Angry Birds Magic. You will now be able to unlock new birds and other different location-based contents in the game.

Also, Angry Birds Magic is yet to receive a release date, the Slashgear says.
