Fallout 4 Settlements

In Fallout 4, the Sole Survivor can build and manage their own settlements at various sites around the Commonwealth. The new workshop interface is used to place and connect pre-fabricated structures, as well as individual pieces (walls, floors, roofs, etc.) letting the player construct their own home base(s) as they desire.

Once built, these settlements can be customized extensively. Inside buildings and structures, furniture, decorations and lights can be placed for aesthetic purposes. However, outside these structures the player can plant crops, create water and power supplies and tend to the defensive needs of their new settlement. In order to accumulate resources for their settlements, the player can scrap most interactive inventory items.

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 supply lines between settlements to share resources and inventory among them.

Settlements require constant maintenance, with NPCs tending to more basic functions such as crop harvesting. However, without this, over time crops fail, and equipment will need repair. The player will have to use the workshop and have the required junk to complete the repairs. Walk up to damaged or failed item while in workshop mode, then the player will be offered a selection to scrap/repair item.

Most of these sites can be obtained during the Minutemen quests however others will require you to visit them and complete location specific quests to obtain the site.



Necessities and dependencies
These stats need to be maintained to sustain or stagnate the growth of a settlement. Each Necessity would also act as a dependency on other necessities; i.e. people need water, food, beds and protection to survive and prosper.
 * People
 * The population of your settlement. People are required to collect from resource units and man objects you build. Each settlement has a default max population of 10 settlers plus each point of charisma your character has, totaling to a maximum of 21 settlers (assuming you use the bobblehead after maxing it out). This can however be further increased by wearing items or taking chems that increase your charisma. A Radio beacon is generally required to attract more settlers, but you can send companions to settlements and you can recruit a few non-companion NPCs to join your settlements as well.
 * Dependencies: Water, Food, Beds, Defense, Radio Beacon


 * Food
 * How much food your settlement is producing. Increased by placing food resources.
 * Dependencies: People


 * Water
 * How much water your settlement has.
 * Dependencies: People, Power (only with water purifiers)


 * Power
 * How much power is available for your settlement to use. Power required for turrets, traps, lights and some furniture (TV).
 * Dependencies: n/a


 * Defense
 * Measures how defensible your settlement is, based on traps, guard posts and turrets you have. Advisable to have a defense rating at least the sum of the food and water ratings.
 * Dependencies: People, Power (with certain turrets and traps)


 * Beds
 * The number of beds in your settlement. Your settlement needs one bed per settler to keep your settlers happy.
 * Dependencies: n/a


 * Happiness
 * Morale of the settlement. Influenced by meeting basic needs and providing trading posts. High happiness increases the productivity of settlers.
 * Dependencies: Beds, Trading stands, Food, Water, Defence


 * Size
 * Shows the amount of objects that have been placed by the player within the settlement, as well as the maximum amount of objects that can be placed through the Settlement interface.
 * Dependencies: n/a

With the Local Leader perk food/water and junk resources can be shared between settlements connected by a supply line, allowing the player to quickly build out new settlements or even specialize them.

Budget Settlement (Sanctuary)
Build supports 20 settlers, minimum 12. When setting up camp, place the medium generator, water purifiers, and recruitment radio beacon close together. The generator can support all 3 items by itself. Each settler can maintain 6 plants, so 4 settlers can maintain 20. Settlers that do not maintain plants can be set to guard duty. Each guard can man 3 guard posts, so 4 settlers can man the 10 posts. Mutfruit plants can be obtained at Greentop Nursery, Graygarden, or Warwick Homestead.

Minimum Cost Alternately, the player character can build x7 water pumps, at a cost of: The disadvantage of water pumps compared to water purifiers is that the purifier will add purified water to the workshop inventory, a benefit to player character's health.

Bugs
(Video Evidence that verifies all three statements above: https://www.youtube.com/watch?v=nJ0RCCVsbII)
 * When defending a settlement that is under attack, the miscellaneous objective might mark itself as "completed" before all enemies are killed.
 * After successfully defending a settlement from an attack, if you interact with any of the settlers, they will proceed with their "thank you" dialogue speech, but never actually finish.
 * After successfully defending a settlement from an attack, interacting with any of the settlers could cause the player to be stuck in an infinite dialogue camera. The player can walk away, but will be unable to press any buttons other than Toggle, Crouch or Options. You can fix this by passing through a section that leads through a loading screen (Diamond City for example), but may prove difficult since the pip-boy button for fast travel is also disabled. The only reliable way of fixing this issue is to reload a save.
