Fallout 76 has released its free Wastelanders update, offering some big gameplay changes alongside bug fixes and other adjustments. The centerpiece of Wastelanders is the addition of NPCs, but there's much more to it than the addition of human quest-givers.
This update brings all versions of the game up to 18.104.22.168, and the download size for the update is rather large–70 GB for PS4 and Xbox One, 54 GB for PC through the Bethesda launcher, and 68 GB for PC through the just-launched Steam version. If you began your game through the Bethesda launcher, you'll carry over any progress and Atomic Shop items to Steam, but Atom balancs and Fallout 1st memberships won't transfer.
Wastelanders adds a new main quest focused on NPCs and factions, including instanced areas where only you and your multiplayer companions can impact the surroundings. You'll build rep with Settlers and Raiders to open up new gear and quests. It also introduces new repeatable quests, new companions, and lots of quality-of-life improvements.
