Map markers are marked locations on the world map or town map.
Fallout and Fallout 2
In Fallout and Fallout 2, map markers are green circles on the world map, some of which can, on re-entering a given location, also be divided into sub-locations, marked with a green triangle on the town map.
In Fallout 3, map markers enable fast travel to the location once discovered.

Map markers in Fallout Tactics are similar to those in Fallout and Fallout 2 but with minor differences. There are large green and gray circles for active and completed missions correspondingly, medium-sized cyan circles for Brotherhood of Steel bunkers and small green circles for special encounters. Locations in Fallout Tactics are not divided in sub-locations.
