June 2 downtime for Fallout 76 began at 10 a.m. ET and is expected to last at least 3-4 hours across all platforms while Bethesda deploys the Infestation update.
More than 40 locations can now randomly turn into Infestation sites, with players unable to know in advance which area or enemy type will take over.
Endgame-focused Infestations raise difficulty above normal world spawns and are built to test coordinated groups rather than routine solo exploration.
4-star Legendary weapons and armor mods are among the highlighted rewards, as Bethesda tries to make Appalachia feel less predictable and more reactive.
