While Yaiba: Ninja Gaiden Z wasn’t exactly the perfect mash-up of zombies and cyborg ninjas, that’s apparently not stopping Koei Tecmo from possibly trying again. The company recently filed a new trademark for the Ninja Gaiden spin-off series. The first game was developed by Spark Unlimited, and was released on PlayStation 3, Xbox 360 and PC back in March 2014 to mediocre reviews.
It’s also worth noting that this new trademark is specifically for “Yaiba: Ninja Gaiden Z,” while the game’s previous trademarks, filed in August 2012, were just for “Yaiba”.
Yaiba: Ninja Gaiden Z followed Yaiba Kamikaze, a ninja killed for massacring his own clan by main series protagonist, Ryu Hayabusa. Later, Yaiba is resurrected by the mysterious organization known as Forge Industries as a cyborg in order to stop a zombie plague (as well as exact his revenge on Ryu).
