Project Sword, the technologically impressive game you've been using to show off your new iPhone 4 to friends, family and Charlie Chaplin, is set to become a full game this holiday. Dubbed "Infinity Blade," the Chair-developed "action-RPG sword fighting adventure" will be available for iPhone 4, iPad and iPod Touch.
Infinity Blade will feature single-player battles within ye olde castle environments and will gradually grant you experience, improved stats and more powerful items. It will be expanded to support a multiplayer mode (and Game Center) via free updates after launch.
According to Epic Games, the Unreal Engine 3-powered demo landed in the hands of over one million people, lured in by the promise of what the company calls "triple-A mobile gaming." How much are people willing to pay for triple-A mobile gaming? Epic has yet to announce a price, but it'll have to be careful not to build a costly moat around its spot on the App Store.
