Inafune said while there are "countless zombie games out there," fans kept telling him they wanted a "new Inafune zombie game."
"I am flattered and grateful, for people associating me as a Zombie Lover," he said. "For that, I must, answer to this expectation. This new concept for my game was born some time after becoming independent.
"I don’t want to spoil everything just yet, but I hope you will enjoy my new game that is loaded with stuff I love: zombies, ninjas, robots, and action. It’s called YAIBA. I hope you are excited. I know I am."
More on the game will come out of TGS next weekend.
