Essentially what the thread titles. Currently, the Hell’s Raiders are the only faction you can’t interact with except in a totally hostile manner. The idea is, that like with any other faction, you could join them and potentially make a difference in the world.
Personally, I’d like to see the player be able to get in charge of large amounts of resources. Say you challenge the former leader of the Hell’s Raiders to combat and best him (spare his life or kill him, your choice. Or perhaps you ask the drunk psychopaths watching the battle what they think). Now suddenly, you’re the leader of the largest and most dangerous faction in the ruins of New England, and everyone civilized wants you dead.
