Infinity Blade by Chair Entertainment Group, LLC
Infinity Blade is one of the top selling apps for the iPhone. If you love dynamic sword fighting, awesome sound effects and beautiful graphics, you will fall in love with this app. The app gives you an orientation of the user interface, so there is nothing to figure out. A few simple gestures with your fingers and you are ready to do battle. The file is quite large (900MB), so keep that in mind. The app goes for $5.99 in the App Store.
