Many of the new features added to the Wii U version are to address issues fans had with the original game. For example, enemy dismemberment returns to the series, with enemies continuing to fight and change tactics after losing a limb.
Ryu will also now have six weapons instead of just the original three, using a sword, claws, scythe, dual katanas, staff and kusari-gama to fight. Each weapon will have its own fighting style, and can also be upgraded using karma points earned throughout the game.
The character Ayane, who only briefly appeared in the original game, will now have her own separate story campaign along with unique weapon fighting styles and abilities.
In addition to Ayane's solo campaign, the main story campaign can now be played co-operatively, with the second player controlling Ayane. Additional playable characters will be released after launch as free DLC.
Test of Valor battle arenas will be added to each chapter, offering an optional challenge against waves of enemies and classic bosses from past Ninja Gaiden games.
Finally, the game will use the Wii U GamePad to easily change weapons and ninpo using the touchscreen, and feature a quick reference ability to check button combos for more elaborate attacks without pausing the game.
Ninja Gaiden 3: Razor's Edge will be available in North America when the Wii U launches on November 18. It will release later in Europe, arriving on January 11, 2013.
