Lost Sector symbol on Nessus.

A lost sector is a dungeon-type activity in Destiny 2 that requires Guardians to explore a mysterious location. At the end of a lost sector is a boss who holds a key to a chest that contains special rewards.[1]

For a list of lost sectors, see the category page.


A lost sector can be looted more than once, but rewards are reduced when looting one again after a short period.
