Tecmo Koei added one feature to the Xbox 360 version of Ninja Gaiden 3: Razor’s Edge that makes it unique. The game supports SmartGlass so you can see your stats on a smartphone or tablet. Ninja Gaiden 3: Razor’s Edge synchronizes to YouTube so you can browse videos that show players how to clear an area. It’s kind of like having an interactive walkthrough at your fingertips.
Actually sounds kinda neat. The idea of watching videos for strategies is especially smart.
