Tecmo Koei's updated port of Ninja Gaiden 3 releases across Europe for Wii U today, under the guise of Ninja Gaiden 3: Razor's Edge.
The team has released the launch trailer for the title, which details many of the new features included over the original PS3 and Xbox 360 game. Such extras include much more gore, dismemberment, more weapons, GamePad-only play, changing weapons and editing characters on the fly using the GamePad, plus new playable characters such as Ayane (and, in future updates, Momiji and Kasumi).
