lost cities changes world generation to add abandoned cities to the game’s terrain generation. These cities spawn independently of biomes, so cities will spawn in all biomes, while biomes will continue to spawn normally.
This new generation of terrain, with cities around the world, will allow us to explore the interior of buildings in search of chests with content. In addition, if we wish, we can establish our base in any of the houses or apartment buildings scattered around the world.
For the mod to work properly we will have to create a new world, so we will have to go to the main menu of the game, click on “Single player”, then on “Create a new world”, select “More world options ” and finally in the types of world we will select the option “World: Lost Cities”.
