This set includes a 50x50 underground camp map (in 25x25 sections) with exterior and interiors of the houses. It also includes darkness, water, and lava versions of the maps, plus versions with no camp dressing so you can make your own. For that it includes house and rubble clusters plus the house interiors as well.
