Fallout 4 Settlements

In Fallout 4, the Sole Survivor can build and manage their own settlements at sites around the game world. The new workshop interface is used to place and connect pre-fabricated structures, letting the player construct their own home base as they desire.

Once built, these settlements can be customized with furniture and decorations, while outside the player can plant food and tend to the defensive needs of their new settlement, setting up various traps and turrets to fend off raider and animal attacks. To find resources for their settlements, the player can scrap nearly any object in the world for parts - even entire previously built structures.

Once a settlement reaches a certain size and/or the player obtains necessary perks, they can invite others to set up shop at their base by building unique resources such as the trading post, which adds a vendor NPC stocking some of the best items in the game. It is also possible to run brahmin caravans between player settlements.
