Here is all you need to defeat the God King, learn the gems and continue to NG+. Along with the official guides, members of the Infinity Blade community have put together some amazing tutorials to help you on your quest.
Epic Gamer and forum member =Silver= is a respected and active member of the the community. Not only that, but he has also had one of the Infinity Blade swords named after him to thank him for his contributions to the community. If you’re looking to use the Dual Wielding weapon class, Silver’s Dual Guide will help you master the class. Silver thanks forum members Bladet, DarthDuck and Aussie3 for their contributions to the thread. Complete with animated gifs from the game, this guide breaks down the moves for the different bosses to assure your success.
If you want to learn more about NG and OG, visit DarthDuck’s NG FAQ thread. The thread also contains links to other useful forum threads. Darth covers attack speeds, the best weapons, difficulty levels and how to get infinite gameplay. Darth has also created an excellent Master Gem List covering each type of Gem.
Pro Gamer Kendall “arCtyC” Smith created two excellent tutorial videos in his “Infinity Blade Tips & Walkthrough Series.” The videos do contain spoilers, so stay clear if you don’t want to know what happens!
