Comcept officially announced Keiji Inafune's zombie game Yaiba today, though it declined to offer much in the way of detail, as we still have no idea of platforms, release window, or even how the game actually works.
According to creator Keiji Inafune, it's inspired in part by fan feedback. "There are so many zombie games out there, yet people ask me for a new Inafune zombie game. I am grateful for people's respect for me as the 'zombie game creator' and to fulfill that I must answer their expectations with YAIBA."
Those expectations are being fulfilled with a concept of "zombies with action, ninjas and mechs." Get an idea of Comcept's concept in this stylish (but bloody) teaser video.
