Season of the Deep brought a new dungeon, Ghosts of the Deep, to Destiny 2. Players band together to tackle dungeon encounters that lie beneath the methane seas of Titan, but not everything is chaotic. In this dungeon, you can discover the two secret chests hidden deep beneath the New Pacific Arcology.

Secret treasure chest 1
Immediately after your opening encounter, you must complete the “Reach the Wreckage” objective. Catch air bubbles, jump, and swim underwater. Move forward until you see the first underwater cliff. Do not fall straight to the bottom. Instead, stick to the left to see an opening in the coral walls.
Go through it, and you will find the first secret treasure chest of the Ghosts of the Deep dungeon inside a cave-like area. When you head deeper into the cave, enemies spawn as part of the “Reach the Wreckage” objective obstacle. 
Secret treasure chest 2
After you have survived and defeated the second boss encounter and gone through an underwater section, you will eventually arrive at a long corridor filled with Hive. This area precedes the final boss, so you can expect heavy resistance.
Before you reach the end of the corridor, defeat the Keeper of the Deep Ogre. Then, on top of the gazebo, you will find the second treasure chest of the Ghosts of the Deep dungeon.
While finding these treasure chests is not challenging, getting to these areas is a difficult task that will test you. For that, we have guides on how to do the first two encounters:
- Destiny 2 Ghosts of the Deep Dungeon Guide – Ecthar Encounter
- Destiny 2 Ghosts of the Deep Dungeon Guide – Opening Encounter
The next time you face the Ghosts of the Deep dungeon, be sure to follow the guide above so you won’t miss any of the secret treasure chests found below the beautiful albeit deadly methane ocean of Titan in Destiny 2.
