Are these the maps that you add in? Or is this a whole mod of the maps? Because I don't want to download it to put in maps I already have.

I really did like these maps. But I don't get what happened in the one ending with the spheres. Message me so it doesn't ruin it for anybody. Also, have you thought about a third part? I would love for this to keep going.
