Fallout 3 locations

General information
Without any of the available add-ons installed, there are 163 marked locations in Fallout 3, provided that the Lawbringer perk and the Contract Killer perk have been selected. Without these, there are 161 as the Regulator HQ and the scrapyard office are not available. The Vault 101 map marker is not counted in the Pip-Boy 3000 "locations discovered" statistic, resulting in a maximum displayed value of 162 discovered locations.

Operation: Anchorage, The Pitt, Broken Steel, Point Lookout, and Mothership Zeta add a total of 10 additional marked locations to the Capital Wasteland map and 52 more on separate world maps, for a total of 225 marked locations. Only 221 are counted towards the "locations discovered" statistic in the stats section of the Pip-Boy 3000.
