Red Chair has released another major update for its highly acclaimed Infinity Blade for iOS devices, adding a third new content pack and a new multiplayer arena. With Infinity Blade: Arena players can now challenge their friends to multiplayer matches via Apple’s Game Center or play in Survivor mode and face off against a legion of Titans. The update also adds a set of new Holiday Helms for every season, two dozen new magic rings, swords, shields and helmets to collect and master. New achievements and more leaderboards are also now available as well as some additional surprises in the game. Infinity Blade 1.3 is a universal app and is currently available from the App Store for $3 for a limited time. The game requires an iPhone 3GS, iPhone 4, third- or fourth-generation iPod touch or iPad running iOS 3.2 or later; it is recommended that users update to the latest version of iOS before playing the game, however.
