Epic Games has released their first full iOS game tonight. Infinity Blade is a gesture-based fighting game that is based on the company's Unreal Engine 3. Epic showed and released a free technology demo of the engine at Apple's 2010 Fall Media event, and has since taken the time to flesh it out into a full game.
TouchArcade reviews the new release and describes it as a "must have" but warns not to expect an open world RPG:
If you were expecting Infinity Blade to be some massive open-world RPG and any number of other things I've seen people on our forums suggesting, you're going to be sorely disappointed. If all you were looking for is a fighting game with a really cool input method that fits perfectly with iOS devices, you're going to be in for a treat. The RPG elements are very light, but the fighting is solid, and the graphics are the best we've seen so far on the App Store.
