Destiny 2 players who’ve spent any time in Faction Rallies over the past year are sick of Lost Sectors — lifeless caves that house minor enemies and chests. But Bungie aims to improve a good-idea-gone-boring from Destiny 2’s vanilla launch with Forsaken. Game Informer reports that dangerous villains from the Prison of Elders will infest Lost Sectors in Forsaken, as well as everywhere else.

In Destiny 2: Forsaken, the location-based Flashpoint milestone will be getting a heap of new activities piled onto it. Players will be able to accomplish other activities aside from Public Events to get their weekly engram. But all of the world events — Public Events included — will now be filled with escaped convicts.
