Whether Amanda Holliday is resurrected as a Guardian or not remains to be seen, but for now, Crow wants some sort of revenge for her unfortunate demise. While the Shadow Legion still has a strong foothold in the EDZ, the first step to taking them down is to destroy one of their flagships floating over the EDZ. This guide will walk you through everything you need to know about completing the Season Finale: Retribution in Destiny 2: Season of Defiance.
Destiny 2 Retribution
The first thing that you will need to do is to pick up the quest from Crow in the H.E.L.M. who will ask you to enter the Ascendant Plane. To do so, you will need to star the quest from the Director, right next to The Farm in the EDZ.
Speak with Mara Sov
The quest will take you to Queen Mara Sov. Speak to her to open up a portal which will teleport you to a Shadow Legion ship.
Defeating the Shadow Legion
After arriving in the ship, you will need to progress ahead while defeating some Shadow Legion on the way. There should be nothing that you have not done before so just keep on pushing. At the end of the tunnel, shoot the vent to arrive in a room with some Psions. Once again, push through the vent and then the door down below.
Destroy the Pyramind Beacons
In the next area, you will see a Pyramid floating in the middle along with a few Pyramid Beacons nearby. I think there is an infinite enemy-spawn wave here so it is best to deal with Pyramid Beacons as quickly as you can. You can obviously deal with enemies if the rooms gets too hectic but it should not prove too difficult, even if you are solo. Once you are done, some more Pyramid Beacons will spawn on either side of the room. After dealing with them, ignite the Balefire in the middle of the room.
You need to make sure that you standing in the Balefire as it will protect you from the blast in the room, thanks Crow!
Finding the Engine Room
From there, you will need to progress ahead in order to find the Engine Room. Before you can do that, however, you will need to deal with 2 Elites. Use your Power Ammo if you have some of it left before pushing forward. In the next room, you will see Mithrax dealing with some Shadow Legion on his own. Leave him to his devices and push forward to pick up a Favor from Mara Sov.
Destroying Cooling Fans
The Favor that Mara Sov offers us is not something that we have had in Season of Defiance as of yet. After picking it up, shoot the large door in front of you to destroy it. Remember that her Favor will keep on spawning indefinitely so there is no need to sweat it if you ever run out of time.
In the Engine Room, you will need to destroy Cooling Fans, 2 on each side of the room. However, you will not be able to destroy these as they are grated. To be able to destroy these, you will need to shoot the red cylinders scattered in the room. In addition to this, you will also need to deal with Scorpion Turrets in the room and a bunch of adds. Weapons like Trinity Ghoul, Osteo Striga, Riskrunner, LMGs, etc. are really good for this room.
Kill the Engineers
After destroying the cooling fans, you will need to deal with a couple of Cabal Engineers in the room. These are yellow-bar enemies that are not tough to defeat. Use your Supers, Heavy Ammo, etc. since this is the last combat sequence of the mission.
After you have dealt with the Cabal Engineers, you will need to use the Favors from Queen Mara Sov to destroy the Engine. After that, you simply need to open the portal back to The Farm where you will need to speak with Crow via the Holoprojection to complete the mission. Fun fact: if you look at the skybox, you will see the smoking remains of the ship you just annihilated. You will receive an Ascendant Shard for your troubles.
