The Sundered Doctrine dungeon in Destiny 2 plunges Guardians into a fractured battleground where ideology and power have violently collided, leaving behind a domain shaped by conflict and instability. Set within a corrupted stronghold overtaken by hostile forces, the dungeon explores the consequences of a broken belief system, as players push through environments warped by opposing influences. As the path unfolds, Guardians uncover the remnants of a once-unified purpose now splintered into chaos, forcing them to confront the fallout of a doctrine that has collapsed under its own weight.

As a three-player endgame activity, Sundered Doctrine challenges fireteams with mechanics centered around managing divided states and adapting to shifting encounter conditions. Players must coordinate closely to navigate evolving objectives while facing increasingly dangerous enemies, culminating in a final encounter that tests both execution and awareness. With its focus on dynamic mechanics and thematic tension, the dungeon delivers a demanding experience that rewards teams capable of maintaining control in the midst of disorder.
