these maps are mod maps with cool sides but i put them in Cloud City by adding a map of cloud city. the authors of the maps are guys you know. for a cleaner cloud city put the bes2.lvl file from the mod map RCC and you get a less cluttered cloud city BFS, heroassault, and RhVC maps made by guys you know but now set to take place on cloud city, if you want the original map file it is left in map but renamed with a 9 in front of the file name.
