Fallout 4: Southern Boston Map Fallout 4 Guide

The above M9 map shows the ninth sector of the world map in Fallout 4. It's the southern and southeastern part of the game world which is also the southern part of Boston. Yellow dots on the map mark locations in which you can start some quest (main, side or faction one). Red dots symbolize other locations. You will not unlock any quests there, but they might be related to quests started in other parts of the game world.
