Infinity Blade III launching alongside iPhone 5S next week

Epic Games debuted Infinity Blade III alongside Apple's new iPhone 5S today. The "epic conclusion of the Infinity Blade trilogy" takes advantage of the smartphone's improved power to run five times faster than on iPhone 5, Chair Entertainment founder Donald Mustard said.

Infinity Blade III will star two main characters who can explore huge regions between classic swipe-and-tap battles, as opposed to the limited scenes of Infinity Blade I and II. Thanks to iPhone 5S' OpenGL ES 3.0 support, Chair can add "lens flares that would make J.J. Abrams proud," Mustard said.

It will launch just before iPhone 5S on Sept. 18. Check out the trailer below for your first look at the game in action.
