Like the rest of the world, the non-playable characters in Fallout 76 have to stay inside a little while longer. The only difference is that unlike us, they’ve never seen the light of day.
Bethesda has been forced to delay the upcoming Fallout 76: Wastelanders expansion by an extra week due to the ongoing COVID-19 crisis. Subsequently, the Steam release is also delayed another week. The developers have shifted to working remotely and it has altered their normal workflow, pushing timelines back as everyone figures out the most efficient ways to deal with this situation. Bethesda is hardly alone in this disruption.
