Yesterday, at Apple's "Let's Talk iPhone" event, Infinity Blade 2 was announced exclusively for the iPhone, iPad and iPod touch. Powered by the Unreal Engine 3, Infinity Blade 2 will take advantage of the newly announced iPhone 4S, which boasts graphics speeds of up to 7X faster than the previous iPhone. Sales figures for the original Infinity Blade were also revealed and Epic Games has brought in over $20 million in revenue on over 5 million paid downloads of the game. With those figures, it should come as no surprise that the sequel is ready to be the flagship game for the new iPhones. The iPhone 4S hits the streets on October 14 and you can download Infinity Blade 2 on December 1.
