From VG247: “The Destiny 2: Forsaken three-weekly reset is coming at 6 pm BST and fans are hoping that now weve reached October, the Festival of the Lost will be available soon.
Bungie has previously released a 12-month roadmap of what we can expect from Destiny 2: Forsaken, such as the inclusion of the Festival, an ever-evolving Dreaming City and various endgame experiences.”
