Wastelanders, the free Fallout 76 expansion that is set to reintroduce human NPCs to the Appalachian wasteland, got new screenshots as the developers showcased two new factions coming to the game: the Settlers and the Raiders.

Bethesda Game Studios noted that both Fallout 76 locations (Foundation and Crater) will be completely revamped with Wastelanders, featuring new vendors, crafting areas, and plenty of human NPCs to talk to. That said, the interactions with said NPCs will depend heavily on the reputation you have with the respective factions; Bethesda promised to divulge more next week about this new reputation system that's being added to Fallout 76 with Wastelanders.
