This Map has 18 waves of zombies... it is in a Obsidain Block like structure that is around 25-30 blocks big average who knows, this map is entirely made of command blocks besides the hand made structures, the waves do not need to be in order, you can beat wave 5, then go to wave 2 if u want, its not limited, waves 13-18 are hardcore waves, they DO NOT need to be beaten, but if you want to beat them, suit yourself, goodluck : )
