Although there are more Angry Birds games than Slipknot band members, Rovio hasn't made a sequel for the original title that launched all the way back in 2009.

As with recent Rovio titles, the base game itself is free, and comes with several in-app purchases. With over 1.5 billion downloads, the Angry Birds franchise certainly needs no introduction. The only question that remains is: How many of you are going to download Angry Birds 2?
