It's been three and a half years since Angry Birds was first released and you thought it was finally over. You disconnected your internet, set up your shack in the woods, and you're living off the land without ties to the metal world. It's over, right? There are no more birds to be flung. They can't touch you here. At last, you can relax, send a carrier pigeon to the two friends who still talk to you and invite them over for a tree bark barbecue.
