The third installment of the Infinity Blade trilogy has been a long time coming. We thought we would see its release sometime during iOS 6’s lifespan, but the app had been postponed nearly to death. Last week, Apple showed off Infinity Blade III at its iPhone event with a promise that it would launch alongside iOS 7. Well, the game’s developer has made good on its promise. Infinity Blade III is now on sale in the App Store.
