“Head deeper into the Hive nest to stop the Devil Splicers.”
“Descend into the Nest” is an objective in the mission The Wretched Eye in Destiny: Rise of Iron
Walkthrough[edit]
Go through the tunnel where the SIVA Node was. Jump down to the floor below the catwalk you are on. Go forward and through the door. Go through the next room to the entry way. There are a number of Splicers which will head to this area and reinforce the entrance. You will have to either fight through them or just get away from there. It is a number of Splicer Vandals that will be behind the door.
While you are clear the Vandals and then you will have to worry about the SIVA Turret. Clear out the remaining enemies and Ghost will detect more SIVA Nodes that you will need to find.
