A few months ago Epic Games released a tech demo on Apple's App Store called Epic Citadel to show off how their technology can run on an iPhone/iPad. Featuring bump offset mapping, normal mapped architecture, global illumination, real-time reflections, dynamic specular lighting with texture masks, the demo took everyone by surprise at just how incredible it looked. Now it's been revealed that the demo will become a full game entitled Infinity Blade and will be released on the App Store sometime during the "holiday season 2010". In addition, the forthcoming game will feature Game Center compatibility. The price has not yet been announced. If you have an iOS device and haven't already seen the Epic Citadel demo then fire up the app store and download it for yourself - it's absolutely free and you'll be amazed at just how good it looks.
