The game world of Fallout 4 is dominated by 4 different factions - Minutemen, the Railroad, the Brotherhood of Steel and the Institute. Your relationships with individual factions is not a minor issue, but rather one of the main pivotal points of the game. Each faction has its own quests, its own headquarters and its own vision of the future of the Wastes. In addition to that, which faction you decide to side with, affects the game's ending. Below, you can find a number of general information about each of the factions. On the following pages, you will find walkthroughs for quests of each of the factions.
- At the beginning of the game, i.e. soon after you leave Vault 111, you can start your cooperation with three, out of the four. These are Minutemen, the Brotherhood of Steel and Railroad. You come into contact with the Institute later into the game, after you have completed all of the initial quests of the main storyline. (you need to complete all of the quests, up to Molecular Level ).
- After you meet with the leader of each individual faction, and you do not prove hostile towards them, you receive the first quest, or even a number of quests. Without much consideration, you can accept initial quests from each of the factions (both main and side), because this will not deteriorate your relationships with the rest of the factions, regardless of whether you have already discovered them or not. Of course, interests of factions, in general, go against each other and sooner or later, you will have to decide which faction you want to side with for good., but you get to take this decision only after you have made sufficient progress into the storyline (in its part that is not connected with any of the factions).
- Each faction has a set of main and side quests. You complete main quest in the predefined order and according to different rules. They can become available, e.g. after you have bonded with the faction sufficiently, after you meet up with minor NPCs in the HQ of that faction, or after you receive a radio message. Objectives of many of such side quests are random (e.g. defeat monsters in location X). What is even more, many of them are replayable and this is a good way to obtain more experience or more Caps.
- Of course, factions have their headquarters. In the case of Railroad, and the Institute, their location remains unchanged throughout the game. When it comes to the Brotherhood of Steel and Minutemen, they change their headquarters with time (e.g. in the case of Minutemen these are Museum of Freedom, Sanctuary Hills and the Castle). While staying at the HQ of a faction, you re completely safe . Apart from that, you can find there e.g. workbenches or beds that you can use for free.
- After you permanently bond with one faction, you will be able to focus on reaching its final quest. In the case of the Institute, it is Nuclear Family. IN the case of the remaining factions, it is The Nuclear Option, where the course of the quest is different for each of these factions (the only thin they share is the name of the quest).
- If you have become enemy with a given faction, as a result of your actions, not only will you miss the rest of its quests, but also you will be attacked on sight by its members, after you encounter them or after you enter the HQ. After you enter the warpath with a given faction, you also lose the companion connected with that faction - in the case of Minutemen, it is Preston Garvey, for the Brotherhood of Steel, this is Paladin Danse, for Railroad it's Deacon, and in the Institute it is X6-88.
