Part 21

Draksis: Engage Draksis, an Ultra Fallen Captain, and his Kell's Guard. Use cover and aim for headshots for Precision Damage. After defeating Draksis, retrieve the Strange Trinket and return it to the Cryptarch at the Tower.

Campus 9: Proceed through Ember Caves to the Citadel, defeat a Major Minotaur and two regular Minotaurs guarding a conflux. Scan the conflux. Head to Campus 9, a Darkness Zone. Destroy the Transfer Gates to eliminate waves of Vex. Defeat the Hydra by targeting its glowing yellow eye, then retreat to avoid its explosion.

Endless Steps: Exit Campus 9 into Endless Steps. Ascend the stairway to summon Gate Lord Zydron, an Ultra Minotaur. Retreat to the staircase to engage Zydron, targeting its midsection for Precision Damage. Defeat lesser Vex and use Super Abilities and Heavy Weapons on Zydron. Upon Zydron's defeat, you will be transported to the Reef, unlocking Mars.

N/Gen Branch: Enter Ishtar Commons and proceed to the N/Gen Branch. Clear out Fallen enemies, including a Major Servitor that spawns two more upon destruction. Retreat to the entrance to engage Vandals from a distance and destroy Shanks. Beware of the Captain that spawns with the Major Servitor. Move to the second floor and enter Dig Site 4, clearing out Vex and Fallen. Be cautious of Vex spawning near the entrance. Engage Hobgoblins with Sniper Rifles and Minotaurs with Fusion Rifles.

The Nexus: Traverse a cave where a large pack of Goblins will attack. These can be easily defeated with regular weapons or Super Abilities, making this area suitable for farming Engrams. To farm, reach the ledge before the drop into The Nexus, receive a checkpoint, then return and jump into the abyss to respawn before the Goblin pack.
