The Pit of Heresy dungeon in Destiny 2 was released during Season of the Undying in October 2019, sending Guardians deep beneath the surface of the Moon into a sprawling Hive stronghold. Hidden below the Scarlet Keep, this dungeon explores the depths of Hive ritual and power, as players descend into a dark labyrinth filled with ancient magic, towering structures, and relentless enemies. Guided by Eris Morn, Guardians must confront the growing Hive threat and disrupt their efforts before it spreads beyond the Moon.

As a three-player endgame activity, Pit of Heresy emphasizes exploration, platforming, and encounter-based mechanics centered around Hive swords and ritual symbols. Fireteams will face challenging encounters and powerful foes, culminating in a final battle against Zulmak, Instrument of Torment. With its eerie atmosphere, methodical pacing, and unique mechanics, the dungeon offers a distinct experience that blends combat, puzzle-solving, and traversal, rewarding players with powerful gear and materials for their efforts.
