Man, has it been four years already? To think that what has become one of the hottest games on the App Store was released around the same time as Appspy's launch (It was December 2009, but the actual date is kind of vague).
Anyway, in celebration of its aviary powerhouse, Rovio is adding fifteen new levels to the original game. Sure to the dedicated fan, it won't take you long to plough through them, but it's the thought that counts.
Happy Birthday Angry Birds!
(For a treat, go and have a look at our review. It's back when I provided the video voiceover, and it was penned by a young upstart named Andrew) :)
