Under Siege Objectives:

  • Reach the Veil
  • Find Shadow Legion Keycards
  • Examine the Barrier
  • Defend Ghost
  • Lower the Second Barrier
  • Reach the Veil
  • Defeat Shadow Legion Commander

The recommended power for this mission is 1620. Head over to Striders’ Gate to initiate the mission.

Reach the Veil - Destiny 2 Lightfall Campaign Under Siege Mission Objective

Reach the Veil

Make your way through the streets of Neomuna while following the marker to the next area.

Find Shadow Legion Keycards - Destiny 2 Lightfall Campaign Under Siege Mission Objective

Find Shadow Legion Keycards

Once you reach the barricade, you’ll be facing off against more Shadow Legion enemies and even the Vex have started to mobilize. Eliminate the enemies or go past them, but you will need to look for the Shadow Legion Code Bearer and defeat it in order to get a Corrupted Keycard.

After picking up the first key, follow the marker to the next section up ahead to find the next Code Bearer. Defeat it, grab the key, then continue to the next section. Continue doing this until you have all the four keycards needed.

Examine the Barrier - Destiny 2 Lightfall Campaign Under Siege Mission Objective

Examine the Barrier

Follow the next marker to reach the barrier. Then, hack the terminal nearby and let Ghost do its thing.

Defend Ghost - Destiny 2 Lightfall Campaign Under Siege Mission Objective

Defend Ghost

You will then have to defeat the next three waves that will be swarming in your location to protect Ghost while the barrier is being hacked. Once all three waves have been defeated, go inside the building.

Lower the Second Barrier

Shoot at the barrels near the next barrier to clear your path.

Reach the Veil - Destiny 2 Lightfall Campaign Under Siege Mission Objective

Reach the Veil

Continue following the marker inside the building until you reach the part where you can place a rally banner. Then, approach the disruptor and wait for the objective to get updated.

Defeat Shadow Legion Commander - Destiny 2 Lightfall Campaign Under Siege Mission Objective

Defeat Shadow Legion Commander

You will then have a boss fight against Vul’ourn, Shadow Legion Supply Master. It will be fighting along with a lot of ads, so try not to get surrounded and move forward slowly. Once the boss has 25% health left, it will retreat further in and summon more allies. Once it has been defeated, all of the surviving enemies should also retreat. Grab the chest by the upper platform before proceeding.

A cutscene will then play where Ghost will get possessed by The Witness as it telepathically talks to Calus. The mission will then be completed after the cutscene.
