Lost Cities is a brilliant world generator that gives you the option to add post-apocalyptic cities in various scenarios. So you can choose the type of abandoned city-world you want to live in and this mod will randomly generate an entire world full of cities.
Every inch of this new world is now a city that once thrived. You’ll see buildings that are crumbling and full of holes.
And animals take refuge amongst the buildings as there are no humans left to deter them.
Here most of the world is underwater and you’ll have to rely on some clever modes of travel to get around or just build a bunch of boats to keep close. If you get adventurous then you can try and find loot deep in these drowned towers.
