Locations in Fallout Shelter are references to other works in the Fallout series or appear only in Fallout Shelter. Locations are only seen during random encounters or quests. Dwellers can come across locations while exploring; most cannot be entered and are only displayed in the exploration log, but some locations can be explored.
The same location for a quest may appear differently on different playthroughs of the game, in terms of its room layout; these locations may use a set of layout templates that varies, or the layout may simply be randomized.[verification overdue] For example, the Nuka-Cola plant can appear differently between playthroughs, as can the old pier in A Pier into the Future.
