The popular game Pig Shot just turned free in the App Store for a limited time only. Pig Shot is an incredibly addictive action game, where you launch your pig from slingshot to another while avoiding obstacles. The best part comes when you use your pig to fart for temporary speed boost. It is integrated with Open Feint Leaderboard and dozens of achievements to be unlocked. Highscore can be sent via email and challenge can competed by just touching the play button within the email. Check out the review of Pig Shot by Matt here.
