Deep Dive

Deep Dive is an activity introduced with Season of the Deep.

Overview
With the return of Titan, the Vanguard recovered its Deputy Commander, Sloane, as well as her new ally: the fugitive Worm Ahsa, who Sloane has established a link with. In order to strengthen this connection and allow Ahsa to speak with them, Fireteams are sent into the depths of the methane sea to recover patches of the mind-linking fungus Egregore, which grows there in coral form. But the forces of Xivu Arath, God of War lurk beneath the waves, ready to jump onto unsuspecting Guardians.

Gameplay
Deep Dive is a three-person activity accessed from the H.E.L.M. Matchmade and non-matchmade modes are available. Teams will have to navigate corridors submerged in methane, using bubbles on the way to restore their pressure and avoid getting crushed. Eventually, they will reach the Mesopelagic Twilight, where the first encounter will take place. Completing this encounter within the time limit will allow the fireteam to move on to the Bathypelagic Midnight, and then to the Abyssopelagic Abyss, with increasing power difference and one added Modifier. Beating the Abyss encounter or failing any encounter will pull the fireteam into the Aspyxiator's Hollow, where they will fight the final boss and will be allowed to open a chest upon its defeat, whose contents improve the more encounters have been beaten.

There are several different encounters, which can have small variations based on the enemy race taking part in them, either the Hive, Taken or Fallen.

Ahsa's Gift
Before beginning the dive into any depth, players will be allowed to choose one of two "gifts" from the Worm. These are represented by a small dripping ball of Taken-like energy. The gifts can range from protection against an enemy rank to increasing the damage and recharge of abilities. Gifts are permanent until the end of the activity.

Wrathful Predators
During any of the depth encounters, glowing enemies called Wrathful Predators will appear. Defeating these foes will add 15 seconds to the encounter's timer.

Pressure Trial
When an encounter begins, a small Taken ball called a Lure will appear floating somewhere in the area. If all fireteam members interact with this ball, a secondary objective will activate. Completing this objective begins a Pressure Trial, which will add more enemies and extra objectives to the encounter. Completing a Pressure Trial rewards extra coral, and improves the final chest's rewards by one tier. Thus, to get to the maximum tier of 7, a fireteam needs to complete all Pressure Trials.
