Epic, makers of the Unreal 3 Engine, have just released a trailer showing off their upcoming Infinity Blade game for iPhone, iPod touch, and iPad.

Originally introduced as "Project Sword" during the September 2010 Apple Special Event in San Francisco and featured in the latest ad campaigns for iPhone 4 and iPad, ChAIR's ground-breaking new game will be the first to bring the power of Epic's Unreal Engine 3 to Apple's world-class gaming platforms.
