Update Sept. 20: Infinity Blade III gets optimizations for the 64-bit iPhone 5s:

Infinity Blade III, the final entry in the popular action trilogy that was initially demoed at WWDC in 2010, has been released on the App Store ahead of tomorrow’s iOS 7 launch. The newest game in the series was first demonstrated on the iPhone 5s during Apple’s media event earlier this month.

What’s New in Version 1.0.3

– Optimized for 64-bit iPhone 5S – The iPhone 5S features full screen anti-aliasing, bloom, full screen vignettes, distortion, high resolution shadows, and environmental reflections – it looks crazy awesome! – Includes bug fixes to decrease load times and enable In-App purchases

Infinity Blade III features a massive new world and console-quality graphics specially designed to take full advantage of the increased processing power of the iPhone 5s. Despite its optimizations for the latest iPhone hardware, you can play the game on almost any iOS device running iOS 6 or 7, including the fourth-generation iPod touch, iPhone 4, and iPad 2.

Infinity Blade III is available on the App Store for $6.99.
