[Request] I am looking for a type of map

After scouring the forums, I had to post. Sorry, that was my last resort. Anyway, I'm looking for an apocalypse map, or ruins map, or some sort of big city map. I don't want an adventure map, and I don't want a survival map. Just something someone built in creative mode. Any help at all would be appreciated, thanks so much.

Best wishes,
