Ninja Gaiden has always been a hardcore series. It's been hardcore in regards to it's difficulty, and in regards to it's required mastery. From it's early days on the NES to it's more modern debut Tecmo has kept the series faithful to the ninja theme that it's all about. Devotion, and consistent practice are a must if you hope to survive the many challenges contained within. If you've ever played, and completed any of the Ninja Gaiden games as I have you'll no doubt have felt accomplished when it was all said, and done. The same could be said for this latest spin-off about one of Ryu Hayabusa's longtime enemies, if you choose to take it on. While the gameplay in "Yaiba: Ninja Gaiden Z" is unlike any Ninja Gaiden game before it it still holds true to the hardcore formulas of the past. You will face insurmountable odds in the form of zombie hordes as well as larger than life bosses as you try to avenge your death, Kill Ryu Hayabusa, and do the bidding of the shady individual who revived you.
