Download it free from the market!
Ohhh I gotcha Shadez. Yeah, avoid any app titled angry birds that costs money, because it's free! Make sure you download the one from Rovio and you should be good to go!
I hate you guys. I had no idea what this game was and am not a gamer. But I downloaded it anyways and now I can't put it down. My work is now falling behind and you guys are the friggin cause! Damn you!
