iPad 3 update recently, Infinity Blade 2 has a new, more substantial upgrade coming on Thursday. It will tweak the gem interface and let you meld together three gems, creating a single, more powerful jewel. There's also a new game mode, called ClashMob.
ClashMob is a global social game mode where hundreds or thousands of players can come together to take on enemies with massive health pools for the chance to unlock in-game goodies. By recruiting friends into your "Mob," you'll increase your odds at getting some sweet gear, cash, or whatever that particular challenge awards you. You'll be able to enlist folks in your Mob by importing your friends from Facebook and Game Center.
