Updated July 09, 2025, by Ritwik Mitra:A huge part of what makes theFalloutseries special are its many unique factions. Recently, fans of the TV show have gotten a taste of how these groups add more flavor to the irradiated sands of the wasteland. However, Amazon’s stellar adaptation has only scratched the surface of how twisted and varied these factions are. Long-time fans of the series are more than aware of the sheer enjoyment players can have as they interact with these groups and either aid them in their efforts, stand against them for their own reasons, or develop complicated relationships with their members.
13Followers Of The Apocalypse
One Of The Few Factions Actively Trying To Aid People
Given how twisted the world is following the nuclear apocalypse, it’s easy to see why surface-dwellers have forgone their morality in favor of ensuring their survival at all costs. However, there are some groups that actively try to make the lives of survivors better in this wasteland, going out of their way to ensure that people enjoy a great life here.
The Followers of the Apocalypse are a selfless group with this goal in mind. This makes them one of the better factions to support inFallout: New Vegasif players want the Courier to walk on the path of good. They selflessly secure supplies to ensure that they don’t turn down anyone who needs help, which is a noble goal worth appreciating.
12The Railroad
Aim To Free Synths From The Oppression Of The Institute
Given the savage nature of the Commonwealth, it’s easy to see why players may have reservations about helping a faction who is apparently as selfless as possible in their quest to liberate Synths from the oppression of the Institute. However, players who spend some time with this group will realize in no time that the intentions of this faction are genuine.
This makes the Railroad the perfect faction for players who want to stick to the side of good, even if some people complained that the ending route with this faction isn’t that satisfying. Still, it’s a worthwhile faction for players who want to help synths lead a normal life instead of being turned into guinea pigs by the Institute.
