Dojos are peaceful, quiet structures wherein anyone from any race or culture can listen to the wisdom of a sensei and reflect on the Old Ways. Unless you're a zombie, of course. All members of the undead are barred from dojos, but once they invade, they're probably not going to leave quietly. In Dojo Danger for iOS, you employ physics and strategy to purge your ninja dojo of those vile, unclean zombies. On the flipside, you can also play as part of a zombie team that has to hustle ninja invaders out the dojo's door. Hey, the living dead needs peace and tranquility, too.
